+# Getting a single entity
+
+This is a guide on how to retrieve detailed information on a single entity using the OpenAIRE Graph API.
+
+## Endpoints
+Currently, the Graph API supports the following entity types:
+
+- Research products - endpoint: `GET /researchProducts/{id}`
+- Organizations - endpoint: `GET /organizations/{id}`
+- Data sources - endpoint: `GET /dataSources/{id}`
+- Projects - endpoint: `GET /projects/{id}`
+
+You can retrieve the data of a single entity by providing the entity's OpenAIRE identifier (id) in the corresponding endpoint.
+The OpenAIRE id is the primary key of an entity in the OpenAIRE Graph.
+
+:::note
+Note that if you want to retrieve multiple entities based on their OpenAIRE ids, you can use the [search endpoints and filter](./searching-entities/filtering-search-results.md#or-operator) by the `id` field using `OR`. 
+:::
+
+## Response
+The response of the Graph API is a [Research product](../../data-model/entities/research-product.md), [Organization](../../data-model/entities/organization.md), [Data Source](../../data-model/entities/data-source.md), or [Project](../../data-model/entities/project.md), depending on the endpoint used.
+
+## Example
+
+In order to retrieve the research product with OpenAIRE id: `doi_dedup___::2b3cb7130c506d1c3a05e9160b2c4108`, 
+you have to perform the following API call:
+
+[https://api-beta.openaire.eu/graph/researchProducts/doi_dedup___::a55b42c0d32a4a24cf99e621623d110e](https://api-beta.openaire.eu/graph/researchProducts/doi_dedup___::a55b42c0d32a4a24cf99e621623d110e)
+
+This will return all the data of the research product with the provided identifier:
+
+```json

+
+
+The OpenAIRE Graph API provides a comprehensive way for developers to explore the [OpenAIRE Graph](https://graph.openaire.eu/), a vast interconnected dataset that aggregates metadata from a wide range of scholarly resources. 
+The Graph API offers endpoints for accessing and querying this interconnected dataset, enabling users to retrieve detailed information on research products, data sources, organizations, and projects. 
+
+## Base URL and Swagger documentation
+
+The base URL of the Graph API is:
+```
+https://api-beta.openaire.eu/graph/
+```
+
+You can access the API Swagger documentation in [https://api-beta.openaire.eu/graph/swagger-ui/index.html#/](https://api-beta.openaire.eu/graph/swagger-ui/index.html#/).
+
+## Notes
+Please note that the Graph API: 
+
+- is intended for data discovery and exploration, hence you are now allowed to navigate the full result set: you are limited to the first 10,000 results of a search query. If you are interested to access the whole graph, we encourage you to download the [OpenAIRE full Graph dataset](../../downloads/full-graph.md).
+
+- adhers to the [terms of use](../terms.md) of the OpenAIRE public APIs - certain (rate limit) restrictions apply.

+# Making requests
+
+This guide provides examples of how to make requests to the OpenAIRE Graph API using different programming languages.
+
+## Using `curl`
+
+```bash
+curl -X GET "https://api-beta.openaire.eu/graph/researchProducts?search=OpenAIRE%20Graph&type=publication&page=1&pageSize=10&sortBy=relevance%20DESC" -H "accept: application/json"
+```
+
+
+## Using Python (with `requests` library)
+
+```python
+import requests
+
+url = "https://api-beta.openaire.eu/graph/researchProducts"
+params = {
+    "search": "OpenAIRE Graph",
+    "type": "publication",
+    "page": 1,
+    "pageSize": 10,
+    "sortBy": "relevance DESC"
+}
+headers = {
+    "accept": "application/json"
+}
+
+response = requests.get(url, headers=headers, params=params)
+
+if response.status_code == 200:
+    data = response.json()
+    print(data)
+else:
+    print(f"Failed to retrieve data: {response.status_code}")
+
+```
+
+:::note
+Note that when using `curl` you should ensure that the URL is properly encoded, especially when using special characters or spaces in the query parameters. On the contrary, the `requests` library in Python takes care of URL encoding automatically.

+# Filtering search results
+
+Filters can be used to narrow down the search results based on specific criteria. 
+Filters are provided as query parameters in the request URL (see [here](./searching-entities.md) for the available search entpoints). 
+
+Multiple filters can be provided in a single request; they should be formatted as follows:
+`param1=value1&param2=value2&...&paramN=valueN`.
+
+:::note
+Filters are combined using the logical `AND` operator.
+If a filter is provided multiple times, its values are combined using the logical `OR` operator.
+For more information on how to use logical operators when searching and filtering, see [Using logical operators](#using-logical-operators).

+## Using logical operators
+
+The API supports the use of logical operators `AND`, `OR`, and `NOT` to refine your search queries. 
+These operators help you combine or exclude one or more values for a specific filter.
+
+
+### `AND` operator
+
+Use the `AND` operator to retrieve results that include all specified values. This narrows your search. 
+
+Examples:
+
+- Get research products that contain both `"climate"` and `"change"`:
+
+  [https://api-beta.openaire.eu/graph/researchProducts?search=climate AND change](https://api-beta.openaire.eu/graph/researchProducts?search=climate%20AND%20change)
+
+- Get research products that are classified with both Fields of Study (FOS) `"03 medical and health sciences"` and `"0502 economics and business"`:
+
+  [https://api-beta.openaire.eu/graph/researchProducts?fos="03 medical and health sciences" AND "0502 economics and business"](https://api-beta.openaire.eu/graph/researchProducts?fos=%2203%20medical%20and%20health%20sciences%22%20AND%20%220502%20economics%20and%20business%22)
+
+:::note
+Note that when multiple tokens denote a single filter value, you should enclose them in double quotes, as in the FOS example above.
+:::
+### `OR` operator
+
+Use the `OR` operator to retrieve results that include any of the specified terms. This broadens your search.
+The same functionality can be achieved by providing multiple times the same query parameter or using a comma to separate the values.
+
+Examples:
+
+- Get research products with the OpenAIRE ids `doi_dedup___::2b3cb7130c506d1c3a05e9160b2c4108` or  `pmid_dedup__::1591ebf0e0698ed4a99455ff2ba4adc0`:
+
+    [https://api-beta.openaire.eu/graph/researchProducts?id=r3730f562f9e::539da48b3796663b17e6166bb966e5b1 OR pmid_dedup__::1591ebf0e0698ed4a99455ff2ba4adc0](https://api-beta.openaire.eu/graph/researchProducts?id=r3730f562f9e::539da48b3796663b17e6166bb966e5b1%20OR%20pmid_dedup__::1591ebf0e0698ed4a99455ff2ba4adc0)
+
+- Get projects that are connected to organizations in the US or Greece:
+
+    [https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US OR GR](https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US%20OR%20GR)
+
+    or by using the same query parameter multiple times: [https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US&relOrganizationCountryCode=GR](https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US&relOrganizationCountryCode=GR)
+
+    or just using comma: [https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US,GR](https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US,GR)
+
+### `NOT` operator
+
+Use the `NOT` operator to exclude specific terms from your search results. This refines your search by filtering out unwanted results. 
+
+Examples:
+
+- Get research products that contain `"semantic"` but not `"web"`:
+    
+    [https://api-beta.openaire.eu/graph/researchProducts?search=semantic NOT web](https://api-beta.openaire.eu/graph/researchProducts?search=semantic%20NOT%20web)
+
+- Get all data sources that are not journals:
+
+    [https://api-beta.openaire.eu/graph/dataSources?dataSourceTypeName=NOT Journal](https://api-beta.openaire.eu/graph/dataSources?dataSourceTypeName=NOT%20Journal)
+
+
+:::note
+All the above operators can be combined, along with parentheses, and quotes to create more complex queries.

+# Searching entities
+
+This is a guide on how to search for specific entities using the OpenAIRE Graph API.
+
+## Endpoints
+
+Currently, the Graph API supports the following entity types:
+* Research products - endpoint: [`GET /researchProducts`](https://api-beta.openaire.eu/graph/researchProducts)
+* Organizations - endpoint: [`GET /organizations`](https://api-beta.openaire.eu/graph/organizations)
+* Data sources - endpoint: [`GET /dataSources`](https://api-beta.openaire.eu/graph/dataSources)
+* Projects - endpoint: [`GET /projects`](https://api-beta.openaire.eu/graph/projects)
+
+Each of these endpoints can be used to list all entities of the corresponding type.
+Listing such entities can be more useful when using the [filtering](./filtering-search-results.md), 
+[sorting](./sorting-and-paging.md#sorting), and [paging](./sorting-and-paging.md#paging) capabilities of the Graph API.
+
+## Response
+
+The response of the aforementioned endpoints is an object of the following type: 
+
+```json
+{
+    header: {
+        numFound: 36818386,
+        maxScore: 1,
+        queryTime: 21,
+        page: 1,
+        pageSize: 10
+    },
+    results: [
+        ...
+    ]
+}
+```
+
+It contains a `header` object with the following fields:
+- `numFound`: the total number of entities found
+- `maxScore`: the maximum relevance score of the search results
+- `queryTime`: the time in milliseconds that the search took
+- `page`: the current page of the search results (when using basic pagination)
+- `pageSize`: the number of entities per page
+- `nextCursor`: the next page cursor (when using cursor-based pagination, see: [paging](./sorting-and-paging.md#paging)
+
+Finally, the `results` field contains an array of entities of the corresponding type (i.e., [Research product](../../../data-model/entities/research-product.md), [Organization](../../../data-model/entities/organization.md), [Data Source](../../../data-model/entities/data-source.md), or [Project](../../../data-model/entities/project.md)).

+# Sorting and paging
+
+The OpenAIRE Graph API allows you to sort and page through the results of your search queries. 
+This enables you to retrieve the most relevant results and manage large result sets more effectively.
+
+## Sorting
+Sorting based on specific fields, helps to retrieve data in the preferred order. 
+Sorting is achieved using the `sortBy` parameter, which specifies the field and the direction (ascending or descending) for sorting.
+
+* `sortBy`: Defines the field and the sort direction. The format should be `fieldname sortDirection`, where the `sortDirection` can be either `ASC` for ascending order or `DESC` for descending order.
+
+The field names that can be used for sorting are specific to each entity type and can be found in the `sortBy` field values of the [available paremeters](../searching-entities/filtering-search-results.md#available-parameters).
+
+Note that the default sorting is based on the `relevance` score of the search results.
+
+Examples:
+
+- Get research products published after `2020-01-01` and sort them by the publication date in descending order:
+
+    [https://api-beta.openaire.eu/graph/researchProducts?fromPublicationDate=2020-01-01&sortBy=publicationDate DESC](https://api-beta.openaire.eu/graph/researchProducts?fromPublicationDate=2020-01-01&sortBy=publicationDate%20DESC)
+
+- Get research products with the keyword `"COVID-19"` and sort them by their (citation-based) popularity:
+
+    [https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=popularity DESC](https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=popularity%20DESC)
+
+Note that you can combine multiple sorting conditions by separating them with a comma.
+
+Example: 
+
+- Get research products with the keyword `"COVID-19"` and sort them by their publication date in ascending order and then by their popularity in descending order:
+
+    [https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=publicationDate ASC,popularity DESC](https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=publicationDate%20ASC,popularity%20DESC)
+
+## Paging
+
+The OpenAIRE Graph API supports basic and cursor-based pagination. In basic pagination, `page` and `pageSize` parameters are used, enabling you to specify which part of the result set to retrieve and how many results per page.
+
+### Offset-based paging
+Offset-based paging should be used to retrieve a small dataset only (up to 10000 records).
+* `page`: Specifies the page number of the results you want to retrieve. Page numbering starts from 1.
+
+* `pageSize`: Defines the number of results to be returned per page. This helps limit the amount of data returned in a single request, making it easier to process.
+
+Example: 
+- Get the top 10 most influential research products that contain the phrase "knowledge graphs":
+
+    [https://api-beta.openaire.eu/graph/researchProducts?search="knowledge graphs"&page=1&pageSize=10&sortBy=influence DESC](https://api-beta.openaire.eu/graph/researchProducts?search=%22knowledge%20graphs%22&page=1&pageSize=10&sortBy=influence%20DESC)
+
+response:
+```json
+{
+    header: {
+        numFound: 36818386,
+        maxScore: 1,
+        queryTime: 21,
+        page: 1,
+        pageSize: 10
+    },
+    results: [
+        ...
+    ]
+}
+```
+
+### Cursor-based paging
+Cursor should be used when it is required to retrieve a big dataset (more than 10000 records).
+* `cursor`: Cursor-based pagination. Initial value: `cursor=*`. 
+
+Example:
+-  [https://api-beta.openaire.eu/graph/researchProducts?search="knowledge graphs"&pageSize=10&cursor=*&sortBy=influence DESC](https://api-beta.openaire.eu/graph/researchProducts?search=%22knowledge%20graphs%22&pageSize=10&cursor=*&sortBy=influence%20DESC)
+
+response:
+```json
+{
+    header: {
+        numFound: 36818386,
+        maxScore: 1,
+        queryTime: 21,
+        pageSize: 10,
+        nextCursor: "AoI/D2M2NGU1YjVkNTQ4Nzo6NjlmZTBmNjljYzM4YTY1MjI5YjM3ZDRmZmIyMTU1NDAIP4AAAA=="
+    },
+    results: [
+        ...
+    ]
+}
+```
+Use `nextCursor` value, to get the next page of results.

 For example, a metadata record about a project carries information for the creation of a Project entity and its participants (as Organization entities). It is important, once each piece of information is extracted from such packages and inserted into the OpenAIRE information space as an entity, for such pieces to keep provenance information relative to the originating data source. This is to give visibility to the data source, but also to enable the reconstruction of the very same piece of information if problems arise.

By sustaining the current successful infrastructure, comprised of a human network and robust technical services, it consolidates its achievements while working to shift the momentum among its communities to Open Science, aiming to be a trusted e-Infrastructurewithin the realms of the European Open Science Cloud.In this next phase, OpenAIRE-Advance strives to empower its National Open Access Desks (NOADs) so they become a pivotal part within their own national data infrastructures, positioningOA and open science onto national agendas. The capacity building activities bring together experts ontopical task groups in thematic areas(open policies, RDM, legal issues, TDM), promoting a train the trainer approach, strengthening and expanding the pan-European Helpdesk with support and training toolkits, training resources and workshops.It examines key elements of scholarly communication, i.e., co-operative OA publishing and next generation repositories, to develop essential building blocks of the scholarly commons.On the technical level OpenAIRE-Advance focuses on the operation and maintenance of the OpenAIRE technical TRL8/9 services,and radically improvesthe OpenAIRE services on offer by: a) optimizing their performance and scalability, b) refining their functionality based on end-user feedback, c) repackagingthem into products, taking a professional marketing approach  with well-defined KPIs, d)consolidating the range of services/products into a common e-Infra catalogue to enable a wider uptake.OpenAIRE-Advancesteps up its outreach activities with concrete pilots with three major RIs,citizen science initiatives, and innovators via a rigorous Open Innovation programme. Finally, viaits partnership with COAR, OpenAIRE-Advance consolidatesOpenAIRE’s global roleextending its collaborations with Latin America, US, Japan, Canada, and Africa."

 _Type: String • Cardinality: ONE_
 
 Main date of the research product: typically the publication or issued date. In case of a research product with different versions with different dates, the date of the research product is selected as the most frequent well-formatted date. If not available, then the most recent and complete date among those that are well-formatted. For statistics, the year is extracted and the research product is counted only among the research products of that year. Example: Pre-print date: 2019-02-03, Article date provided by repository: 2020-02, Article date provided by Crossref: 2020, OpenAIRE will set as date 2019-02-03, because it’s the most recent among the complete and well-formed dates. If then the repository updates the metadata and set a complete date (e.g. 2020-02-12), then this will be the new date for the research product because it becomes the most recent most complete date. However, if OpenAIRE then collects the pre-print from another repository with date 2019-02-03, then this will be the “winning date” because it becomes the most frequent well-formatted date.

After collection, metadata are transformed according to the OpenAIRE internal metadata model, which is used to generate the final OpenAIRE Graph, accessible from the [OpenAIRE EXPLORE portal](https://explore.openaire.eu) and the [APIs](https://graph.openaire.eu/develop/).
 
 The transformation process includes the application of cleaning functions whose goal is to ensure that values are harmonised according to a common format (e.g. dates as YYYY-MM-dd) and, whenever applicable, to a common controlled vocabulary. The controlled vocabularies used for cleansing are accessible at [api.openaire.eu/vocabularies](https://api.openaire.eu/vocabularies/). Each vocabulary features a set of controlled terms, each with one code, one label, and a set of synonyms. If a synonym is found as field value, the value is updated with the corresponding term. 
-In addition, the OpenAIRE Graph is extended with other relevant scholarly communication sources that need special handling, either because they do not strictly follow the OpenAIRE Guidelines or due to the vast amount of data of data they offer (e.g. DOIBoost, that merges Crossref, ORCID, Microsoft Academic Graph, and Unpaywall).

+
+This section describes the procedure used to integrate the contents from [Crossref](https://www.crossref.org) and [Unpaywall](https://unpaywall.org) in the OpenAIRE Graph.
+
+## Data acquisition
+
+The dataset containing all the Crossref records is obtained via a complete data dump on a monthly basis. 
+The Unpaywall dataset is no longer updated anymore but its latest snapshot (Dec 2021) is used to enrich the Crossref contents.
+
+## Process
+
+In the following we describe the process applied to the Crossref & the Unpaywall contents.
+
+### Crossref filtering

+Possible improvements:
+* map `clinical-trial-number` and `alternative-id` in `alternateIdentifiers`?
+* Verify if Crossref has a property for `language`, `country`, `container.issnLinking`, `container.iss`, `container.edition`, `container.conferenceplace` and `container.conferencedate`

+# Microsoft Academic Graph
+
+## Data acquisition
+The Microsoft Academic Graph dataset is generated from the latest released version of the graph, 06-12-2021.
+
+### Changes from the previous version
+
+* New workflow: MAG is no longer created within the DOIBoost process. Now, a new workflow normalizes the various MAG tables into a single table, from which the action set is generated.
+* MAG discontinued: It is important to note that MAG has been finished. Therefore, normalization only occurs once data is imported from a complete dump of MAG.
+
+
+## Process
+
+The Microsoft Academic Graph (MAG) is a heterogeneous graph that contains scientific publication records, citation relationships between those publications, as well as authors, institutions, journals, conferences, and fields of study. The MAG schema is designed to capture the rich and complex relationships between these entities.
+
+The main node types in the MAG schema are:
+
+* `Paper`: Publications represent works of scientific research, such as articles, books, and book chapters.
+* `PaperAbstractsInvertedIndex`: used to map the paper abstracts
+* `Authors`: Authors represent the people who wrote the publications.
+Institutions: Institutions represent the organizations with which the authors are affiliated.
+* `Journals`: Journals represent the periodical series in which the publications are published.
+* `Conferences`: Conferences represent the academic meetings in which the publications are presented.
+
+The main edge types in the MAG schema are:
+
+* `Citation relationships`: Citation relationships connect citing publications to cited publications.
+* `Affiliation relationships`: Affiliation relationships connect authors to the institutions with which they are affiliated.
+
+### Preprocess
+
+In the first phase, a normalized table is defined containing all papers and associated relationships.
+
+### Mapping MAG properties into the OpenAIRE Graph
+
+Properties in OpenAIRE research products are set based on the logic described in the following table:

+# Open Researcher and Contributor ID (ORCID)
+
+ORCID (Open Researcher and Contributor ID) is a non-profit organization that provides a unique identifier for researchers. ORCID iDs are used to connect researchers with their contributions, such as publications, grants, and affiliations.
+
+This document describes how OpenAIRE collects information about the researcher profiles and their works from the ORCID. 
+
+## Data acquisition
+
+The ORCID full dataset can be downloaded publicly from [Figshare](https://orcid.figshare.com/) and are described on the [ORCID website](https://support.orcid.org/hc/en-us/articles/360006897394-How-do-I-get-the-public-data-file).
+These datasets represented the initial import, whereas to keep up with the updates in the data a scheduled process retrieves the delta regularly.
+
+The ORCID dataset consists in different compressed files containing information about researchers in XML format. Once uncompressed, the information extracted from the XML records was used to populate the three tables described below.
+
+ORCID provides an API to get incremental updates, the parsed incremental data can be used to update the three tables with the latest changes.

 The OpenAIRE Graph is populated by aggregating metadata records from distinct data sources whose content typically overlaps. For example, the collection of article metadata records from publisher' archives (e.g. Frontiers, Elsevier, Copernicus) and from pre-print platforms (e.g. ArXiv.org, UKPubMed, BioarXiv.org). In order to support monitoring of science, the OpenAIRE Graph implements record deduplication and merge strategies, in such a way the scientific production can be consistently statistically represented. Such strategies reflect the following intuition behind OpenAIRE monitoring: "Two metadata records are equivalent when they describe the same research product, hence they feature compatible resource types, have the same title, the same authors, or, alternatively, the same PID". Finally, groups of duplicates can be whitelisted or blacklisted, in order to manually refine the quality of this strategy. 
 
-It should be noticed that publication dates do not make a difference, as different versions of the same product can be published at different times; e.g. the pre-print and a published version of a scientific article, which should be counted as one object; abstracts, subjects, and other possible related fields, are not used to strenghten similarity, due to their heterogeneity or absence across different data sources. Moreover, even when two products are indicated as one a new version of the other, the presence of different authors will not bring them into the same group, to avoid unfair distribution of scientific reward.

 ### Candidate identification (clustering)
 
-To match the requirements of limiting the number of comparisons, OpenAIRE clustering for research products works with two functions:
-* *DOI-based function*: the function generates the DOI when this is provided as part of the record properties;
-* *Title-based function*: the function generates a key that depends on (i) number of significant words in the title (normalized, stemming, etc.), (ii) module 10 of the number of characters of such words, and (iii) a string obtained as an alternation of the function prefix(3) and suffix(3) (and vice versa) on the first 3 words (2 words if the title only has 2). For example, the title ``Search for the Standard Model Higgs Boson`` becomes ``search standard model higgs boson`` with two keys key ``5-3-seaardmod`` and ``5-3-rchstadel``.
+To match the requirements of limiting the number of comparisons, OpenAIRE
+clustering for research products works with two different strategies based on
+entity types:
 
-To give an idea, this configuration generates around 77Mi blocks, which we limited to 200 records each (only 15K blocks are affected by the cut), and entails 260Bi matches.
+#### Software
+
+* *Title extraction functions*:
+  two clustering functions are applied to the title (normalized, stemming, etc.)
+    * *stats and suffix prefix of words*: the function generates a key that
+      depends on (i) number of significant words in the title, (ii) module 10 of
+      the number of characters of such words, and (iii) a
+      string
+      obtained as an alternation of the function prefix(3) and suffix(3) (and
+      vice-versa) on the first 3 words (2 words if the title only has 2). For
+      example, the title ``Search for the Standard Model Higgs Boson``
+      becomes the two keys ``5-3-seaardmod`` and ``5-3-rchstadel``
+    * *n-grams*: the function generates ngrams from the
+      title. For example, the
+      title ``Search for the Standard Model Higgs Boson``
+      becomes the keys ``tan``, ``sta``, ``ode``, ``mod``, ``ear``, ``hig``,
+      ``igg``, ``sea``
+* *DOI extraction function*: the function generates the DOI when this is
+  provided as part of the record properties
+* *URL extraction function*: the function generates the hostname part provided
+  by the URL of the software, if any
+
+#### Publication, Dataset and Other Research Product
+
+* *PID extraction function*: the function generates the PIDs when at least one
+  is provided as part of the ``pid`` record properties
+* *Author and Title extraction function*: the function generates a key that
+  depends on (i) the number of authors of the product, with a cap of 21
+  authors (ii) number of significant words in the title (normalized, stemming,
+  etc.), divided by 10, and (iii) a string obtained as an alternation of the
+  function prefix(3) and suffix(3) (and vice versa) on the first 3 words (2
+  words if the title only has 2).
+  <br />
+  For example, a product composed by 197 authors and
+  titled ``Search for the Standard Model Higgs Boson``
+  becomes the two keys ``21-0-seaardmod`` and ``21-0-rchstadel``
 
 ### Duplicates identification (pair-wise comparisons)
 
-Comparisons in a block are performed using a *sliding window* set to 50 records. The records are sorted lexicographically on a normalized version of their titles. The 1st record is compared against all the 50 following ones using the decision tree, then the second, etc. for an NlogN complexity.
-A different decision tree is adopted depending on the type of the entity being processed. 
-Similarity relations drawn in this stage will be consequently used to perform the duplicates grouping.

 The comparison goes through different stages:
-1. *trusted pids check*: comparison of the trusted pid lists (in the `pid` field of the record). If at least 1 pid is equivalent, records match and the similarity relation is drawn.
-2. *instance type check*: comparison of the instance types (indicating the subtype of the record, i.e. presentation, conference object, etc.). If the instance types are not compatible then the records does not match. Otherwise, the comparison proceeds to the next stage
-3. *untrusted pids check*: comparison of all the available pids (in the `pid` and the `alternateid` fields of the record). In every case, no similarity relation is drawn in this stage. If at least one pid is equivalent, the next stage will be a  *soft check*, otherwise the next stage is a *strong check*.
-4. *soft check*: comparison of the record titles with the Levenshtein distance. If the distance measure is above 0.9 then the similarity relation is drawn.
-5. *strong check*: comparison composed by three substages involving the (i) comparison of the author list sizes and the version of the record to determine if they are coherent, (ii) comparison of the record titles with the Levenshtein distance to determine if it is higher than 0.99, (iii) "smart" comparison of the author lists to check if common authors are more than 60%.

+
+### Duplicates grouping
+
+The aim of the final stage is the creation of records that group all the
+equivalent entities discovered pairwise by the previous step. This is done in
+multiple phases.
+
+#### Transitive closure
+
+As the concluding step of duplicate identification, a transitive closure is
+performed against similarity relations to identify complete groups of duplicated
+records (cliques). If a group exceeds 200 elements, only the first 200 elements
+are included in the group, while the remaining elements are kept ungrouped.
+
+#### Selection of the pivot record
+
+Each group of duplicate records needs to be identified in the final graph with
+an OpenAIRE identifier, derived from a record of the group known as the _pivot
+record_. It is determined after sorting the group of duplicate records by the 
+following criteria:
+
+1. Records with identifiers from a [PID authority](/data-model/pids-and-identifiers#pid-authorities).
+2. Records chosen as pivots in the graph's previous generations.
+3. Publications from CrossRef or datasets from DataCite.
+4. Records with an earlier date of acceptance.
+5. Records with smaller IDs in lexicographical order.
+
+The first sorting criterion is possible because a state table, called "pivot
+history", is maintained across graph generations. It keeps track of which
+records were used as pivot records in what graph, guaranteed to retain data for
+the last 12 months.
+
+#### Creation of representative records
+
+The representative record, also known as the "dedup record", replaces the group
+of deduplicated records in the graph.
+
+##### OpenAIRE identifier of the representative record
+
+The OpenAIRE identifier of the representative record is generated based on the
+identifier of the record chosen as the pivot of the group:
+
+- if the pivot record comes from a "PID authority", the identifier of the
+  representative record is the same, but the "PID Type Prefix" part of the
+  identifier is modified to append ``_dedup``.<br/>
+  For example ```doi_________::d5021b53204e4fdeab6ff5d5bc468032``` will
+  become ```doi_dedup___::d5021b53204e4fdeab6ff5d5bc468032```
+- otherwise the "PID Type Prefix" part will be set to the fixed value
+  ``dedup_wf_002``, and the following hash will be calculated as the MD5 hash of
+  the entire raw id of the pivot record.<br/>
+  For example ``DansKnawCris::0829b5191605bdbea36d6502b8c1ce1g`` will
+  become ``dedup_wf_002::345e5d1b80537b0d0e0a49241ae9e516``
+
+##### Content of the representative record
+
+The representative records inherits properties from the records it merges
+and tracks their provenance. Whenever possible, it preserves all data from the
+merged records, such as the ``instance`` field. In cases where a specific value
+must be chosen, the most representative one is selected. For example, for the
+"dateofacceptance" field, the earliest value is chosen.
+
+##### Merged and singleton representative record
+
+Changes in metadata content or graph construction may lead to cases where
+representative records disappear from the graph:
+
+1. When two or more representative records are merged into one representative
+   record. Put it other terms this happens when a group of duplicated records
+   contains multiple records formerly used as pivot record.
+2. When a record chosen as a pivot record leaves its group and remains alone.
+3. When a record chosen as a pivot record is no longer published by its data
+   source (deletion of the metadata record).
+
+To address these cases, the pivot history table ensures the visibility of
+disappearing representative records for the first two cases. Specifically:
+
+1. In the case of merged representative records, the new representative record
+   and the ones that would be lost are generated and linked as part of the new
+   representative record.
+2. In the case of a record no longer serving as a pivot, a representative record
+   is generated and linked only with that record.
+
+This approach ensures that users can access representative records that would
+otherwise be lost.

+## Algorithmic details of the second method
+
+*Categorization*
+
+The affiliations' strings are imported and undergo cleaning, tokenization, and removal of stopwords. Similar to the “buckets concept”  of the first method, the goal is to split the affiliation strings, as well as the ROR organizations, into coherent groups. To achieve this, data preprocessing has already been conducted on ROR's data, involving the analysis of word frequency ('keywords') within the legal names of ROR's organizations to define specific categories. These categories include universities and institutes, laboratories, hospitals, companies, museums, governments, foundation, and rest organizations. ROR's organizations have subsequently been assigned to these categories based on their legal names. The algorithm employs a similar approach to categorize affiliations into these same groups.
+
+*String Shortening*
+
+The objective is to extract pertinent details from each affiliation string. The algorithm divides the string whenever a comma (,) or semicolon (;) is detected. It then applies specific 'rules' to these segments and retains only those containing relevant keywords. Additionally, it trims down the segments by preserving words in proximity to particular keywords like "university," "institute," "laboratory," or "hospital." As a result, the average string length is reduced from 90 to 35 characters.
+
+*Matching with ROR's Database*
+
+The algorithm checks whether a substring containing a keyword is linked to a legal name or to an alternative name in the organizations listed in the ROR's database. In order to identify the most accurate match, the algorithm employs cosine similarity.. Although alternative methods like Levenshtein Distance or Jaro-Winkler Distance were considered for measuring string similarity, it was concluded that cosine similarity was the most appropriate choice for this specific application.
+
+*Refinement*
+
+If multiple matches are found above the desired similarity thresholds, the algorithm performs another check. It applies cosine similarity between the organizations found in the ROR's database and the original affiliation string. This comparison takes into account additional information present in the original affiliation, such as addresses or city names. The algorithm aims to identify the best fit among the potential matches. Note that the case where two or more different organizations share the same name is also considered.

+# Enrichment from ORCID
+
+OpenAIRE enhances publication metadata by incorporating author information from ORCID. This involves adding persistent 
+identifiers to authors and leveraging ORCID data to improve author disambiguation.
+
+## How does the enrichment work?
+
+The following steps outline how ORCID information is integrated into the OpenAIRE Graph:
+
+### Extracting Author and Work Information and creating ORCID-Work pairs
+OpenAIRE extracts the following from ORCID profiles:
+* Author information: ORCID, family name, given name, other names, credit name
+* Work information: Persistent identifiers (DOI, PMC, PMID, arXiv, handle)
+
+For each work identified by a persistent identifier (PID), a pair is created linking the ORCID to the work PID. For
+example, if an ORCID profile (orcid1) has a DOI (doi1) and a PMC (pmc1) associated with it, the following pairs are generated:
+- P1: `<orcid1, doi1>`
+- P2: `<orcid1, pmc1>`
+
+### Grouping by work persistent identifier
+ORCID-Work pairs are grouped by the work's persistent identifier to identify multiple authors contributing to the same work. 
+Two ORCIDs (orcid1 and orcid2) associated with the same DOI (doi1), result in structures like:
+* `<doi1, [orcid1, orcid2]>`
+
+**Note:**
+* The term "orcidx" refers to a structure containing the ORCID identifier along with the author's name information
+(family name, given name, other names, and credit name) as extracted from the ORCID profile. 
+* The term "doix" refer to a structure
+containing the schema and value of the persistent identifier. In case of the example "doix" : <"doi","10....">
+
+### Matching with the Graph result and enriching the author metadata
+For each persistent identifier pair, OpenAIRE searches for a corresponding result in the Graph based on the pair's
+schema and value. Once a match is found, OpenAIRE attempts to identify the corresponding authors within the result by
+comparing them to the authors listed in the ORCID profile. This process employs an Algorithm called *author name disambiguation*
+to establish the correct matches. Successful matches allow OpenAIRE to enrich the result's author information with the
+ORCID identifier from the profile.
+
+### Author name disambiguation algorithm
+The process involves comparing authors from two sets: those extracted from the graph (graph authors) and those derived 
+from ORCID profiles (ORCID authors) that share the same persistent identifier pair.
+For each graph author, the algorithm iterates through the following matching strategies, ordered by decreasing confidence:
+- Exact fullname match: If the full name of a graph author exactly matches the full name (constructed by concatenating the author given name and family name) of one author in the ORCID list, a match is found.
+- Exact reversed fullname match: Similar to the previous strategy, but the ORCID full name is constructed by concatenating family name and given name.
+- Ordered token match: Author names are tokenized into individual words. These tokens are then ordered and compared for matches or abbreviations. This strategy is applied to names with at least two words and such that the name word difference is two or less. This strategy allow for variability in the name. (some examples will be provided in the following)
+- Exact match of ORCID credit name: If the graph author's full name matches an ORCID author's credit name, a match is considered.
+- Exact match of ORCID other names: The graph author's full name is compared to each other name listed in the ORCID profile.
+
+Upon identifying a match, the graph author's information is enriched with the corresponding ORCID data, and the matched 
+ORCID author is removed from the comparison list. This process continues until no further matches can be found.
+
+By applying this multi-faceted approach, OpenAIRE aims to maximize the accuracy of author identification and linking.
+
+#### Author name disambiguation example
+Consider the following author lists
+- Graph List: Robert Stein, Sjoert van Velzen, Marek Kowalski, Anna Franckowiak, James C. A. Miller-Jones, Sara Frederick, Itai Sfaradi, Assaf Horesh, Albert Kong, Ryan Foley
+- Orcid List: Marek Kowalski, Itai Sfaradi, James Carl Miller-Jones, Assaf Horesh, Kong Albert, Ryan Foley
+
+The graph list contains the full names of the authors as found in the metadata. Any potential ambiguities in splitting names into components (like first name and last name) are addressed by the first three steps.
+The ORCID list names are expressed as the concatenation of the given name and the family name as provided in the ORCID profile
+(i.e. "Kong Alber => Kong is given name and Albert is family name in the ORCID profile) For simplicity, other names and credit names are excluded from this list, since the corresponding strategies can be assimilated to an exact match comparison.
+
+Algorithm Application
+
+First of all the *Exact fullname match* strategy is applied.
+Each graph author's full name is compared to every full name in the ORCID list until a match is found. A full name in the
+ORCID list is constructed by concatenating the given name and family name in the order provided.
+If an exact match is found, the ORCID identifier is used to enrich the corresponding graph's author record, and the ORCID author
+is removed from the list for subsequent comparisons.
+By applying this strategy we can find a match for Marek Kowalski, Itai Sfaradi, Assaf Horesh, Ryan Foley
+
+Then the *Exact reverse fullname match* strategy is applied on the graph and orcid list that have not been match in the previous step:
+- Graph List: Robert Stein, Sjoert van Velzen, Anna Franckowiak, James C. A. Miller-Jones, Sara Frederick, Albert Kong
+- Orcid List: James Carl Miller-Jones, Kong Albert
+
+The process is similar to step one, but the ORCID fullname is constructed by reversing the order of given name and family name.
+This step accommodates variation in name formatting. As before if an exact match is found, the ORCID identifier is used to update the metadata of the
+graph author, and the ORCID author is removed from the list for subsequent comparisons. With this strategy we can find a match for
+Albert Kong.
+
+The third step is the application of the *Oredered token match* strategy to the remaining authors to be matched. Before going to see 
+a running example, let us describe how the strategy works.
+
+The tokens from the two lists are pairwise compared. The outcome of each comparison falls into one of three categories:
+- No Match: This occurs when the initial characters of the compared tokens differ, or when the entire words don't match despite sharing the same starting character. A mismatch indicates that the authors are different, and the comparison process terminates.
+- Short Match: A short match happens when both tokens begin with the same character, but one token consists solely of that character.
+- Long Match: Exact correspondence between the two compared words
+
+When a no match is encountered due to different initial characters, the algorithm proceeds
+to compare the next token in the list with the lexicographically lower preceding token. This allows to be tolerant with missing
+words in one of the two names.
+
+A successful match (short or long) moves the comparison of the subsequent tokens in both lists.
+This iterative process continues until either a no match is determined or both token lists have been exhausted.
+
+If both lists have been exhausted, a match is found if:
+- At list one long match exists
+- The sum of short and long matches equals the length of the shorter token list, indicating that all the words
+  in the shorter list have a match in the longer one.
+
+Going back to the example, the authors that remain to find a match for are:
+- Graph List: Robert Stein, Sjoert van Velzen, Anna Franckowiak, James C. A. Miller-Jones, Sara Frederick
+- Orcid List: James Carl Miller-Jones
+
+Let us consider directly the names that can be matched by this strategy:
+graph name = James C. A. Miller-Jones
+orcid name = Carl James Miller-Jones
+
+So the two names are broken down into individual words or token and sorted alphabetically to standardize the comparison process.
+graph = A C James Miller-Jones
+orcid = Carl James Miller-Jones
+
+The comparison process works as follows:
+
+- *A* and *Carl* are compared. No match since the initial characters are different. The graph list will be moved one step ahead for the next comparison
+- *C* and *Carl* are compared. A short match is detected, since both start with the same character and the graph word is only that character. Both the lists will be moved one step ahead for the next comparison
+- *James* and *James* are compared. A long match is detected. Both the lists will be moved one step ahead for the next comparison
+- *Miller-Jones* and *Miller-Jones* are compared. A long match is found. The lists are exhausted and the computation ends.
+
+Since at list one long match exists and the sum of long and short matches equals the length of the shorter list, the match is confirmed and 
+the graph author can be enriched with the ORCID information.
+
+The ORCID list remains empty after the application of the third strategy and the author name disambiguation process ends. 
+
+Note: the application of the remaining two strategies can be remanded to the application of the *Exact name match* strategy.
+Note: Even if the third strategy can subsume the first two, the reason they are applied before the third is for efficiency. 
+In this way, in fact, 
+we can claim a match as soon as the first pair of matching names is found. Applying only the third strategy, all the comparisons should be done and 
+a way to determine the best match should be found before claiming a match.
+Example:
+
+graph = Mario Enrico Rossi, Mario Rossi
+ORCID = Mario Rossi
+
+Applying only the third strategy, we would associate Mario Rossi's ORCID to Mario Fabrizio Rossi if this one was first in the author list.

+# Sustainable Development Goals
+
+## Introduction
+The Sustainable Development Goals (SDGs) are a set of 17 interconnected global goals established by the United 
+Nations in 2015. 
+They serve as a universal call to action to end poverty, protect the planet, and ensure peace and prosperity for 
+all by 2030. 
+The SDGs are designed to be a blueprint for achieving a better and more sustainable future.

+
+## Application in Classification of Research Products
+
+The SDG taxonomy is used to classify research products based on their relevance to the overarching goals. This 
+classification helps in identifying the impact of research on sustainable development and aligning research efforts 
+with global priorities. Here’s how it can be applied:
+
+1. **Mapping Research Outputs**: Research outputs such as publications are be mapped to specific SDGs based on their 
+   objectives, methodologies, and outcomes.
+2. **Evaluating Impact**: The classification allows for the evaluation of the impact of research on achieving the 
+   SDGs, helping to highlight contributions to specific goals.
+3. **Funding and Collaboration**: Aligning research with SDGs can attract funding from organizations focused on 
+   sustainable development and foster collaborations with other researchers and institutions working towards 
+   similar goals.
+4. **Policy and Decision-Making**: Policymakers can use the classification to identify research that supports 
+   sustainable development policies and make informed decisions based on evidence from relevant research.
+
+By integrating the SDG taxonomy into the classification of research products, we can ensure that research efforts 
+are directed towards addressing the most pressing global challenges and contributing to a sustainable future.
+
+## Conclusion
+
+The Sustainable Development Goals provide a comprehensive framework for addressing global challenges. By applying 
+the SDG taxonomy to classify research products, we can better understand and enhance the impact of research on 
+sustainable development, ensuring that scientific advancements contribute to a more equitable and sustainable world.
+
+Check an example of how the SDG classification appears in the OpenAIRE data in the 
+[data model](../../data-model/entities/research-product#subjects) section.

+# Guide for authenticated requests
+
+The OpenAIRE APIs can be accessed over HTTPS both by authenticated and non authenticated requests.
+You can use authenticated requests to increase the rate limit of your requests (please refer [here](./terms#authentication--limits) for the current API rate limits).
+There are 2 main modes that you can use to authenticate API requests: 
+
+* [Personal access tokens](#personal-access-token)
+* [Registered services](#registered-services)
+
+
+In the following, we elaborate on these modes. 
+
+## Personal access token
+
+To access the OpenAIRE APIs with better rate limits you can use your personal access token. To have access to the following functionalities you need to login to OpenAIRE. In case you are not already a member you will need to register first and provide your [Personal information](https://develop.openaire.eu/personal-info).
+
+:::info New!
+The registration process has been updated! In order to visit the Personal Token and Registered Services functionalities you need to fill in the Personal Information form available [here](https://develop.openaire.eu/personal-info). This update will not affect the operation of your existing services. However, if you want to register a new service or access/modify an existing one, you will need to provide your personal information first.
+:::
+
+### How to create your personal access token
+
+To create your personal access token go to [your personal access token page](https://develop.openaire.eu/personal-token) and copy it!
+
+:::info
+Your access token is valid for an hour.
+:::
+
+:::caution
+Do not share your personal access token. Send your personal access token over HTTPS.
+:::
+
+### How to use your personal access token
+
+To access the OpenAIRE APIs send your personal access token using the Authorization header.
+```js
+GET https://api.openaire.eu/{resourceServicePath}
+Authorization: Bearer {ACCESS_TOKEN}
+```
+
+### An hour is not enough? What to do.
+
+To prolong your access to our APIs you can use a **refresh token** that allows you to programmatically issue a new access token.
+
+To get your refresh tokeng go to [your personal access token page](https://develop.openaire.eu/personal-token) and click the **"Get a refresh token"** button to get your refresh token.
+
+OpenAIRE refresh token expires after 1 month.
+
+In case you already have a refresh token a new one will be issued and the old one will no longer be valid.
+
+Please copy your refresh token and store it confidentially. You will not be able to retrieve it. Do not share your refresh token. Send your refresh token over HTTPS.
+
+Since the OpenAIRE refresh token expires after one month, when a client gets a refresh token, this token must be stored securely to keep it from being used by potential attackers. If a refresh token is leaked, it may be used to obtain new access tokens and access protected resources until a new one is issued or it expires.
+
+To get a personal access token using your refresh token you need to make the following request:
+```js
+GET https://services.openaire.eu/uoa-user-management/api/users/getAccessToken?refreshToken={your_refresh_token}
+```
+
+The response has the following format:
+```json
+{ 
+	"access_token": "...",
+	"token_type": "Bearer",
+	"refresh_token": "...",
+	"expires_in": "...",
+	"scope": "...",
+	"id_token": "..."
+}
+```
+
+## Registered services
+
+If you have a service (client) that you want to interact with the OpenAIRE APIs you need to register it.
+
+:::info
+You can register up to 5 services.
+:::
+
+We offer two ways of authenticting your service: the Basic Authentication and the Advanced Authentication.
+
+### Which one is for me?
+
+|     | How | Client Credential Issuer | Authentication Method |
+| --- | --- | --- | --- |
+| **Basic** | Client ID & Client Secret | OpenAIRE AAI server | Client Secret (Basic) |
+| **Advanced** | Private Key signed JWT | Service owner | Private Key JWT Client Authentication |
+
+For the **Basic Authentication** method the OpenAIRE AAI server generates a pair of _Client ID_ and _Client Secret_ credentials for your service upon its registration. The service sends the client id and client secret when authenticating to the OpenAIRE AAI Server to obtain the access token for the OpenAIRE APIs. The OpenAIRE AAI server checks whether the client id and client secret sent is valid. [Continue reading for the Basic Authentication](#basic-service-authentication-and-registration).
+
+For the **Advanced Authentication** method your service does not send a client secret but it uses a _self signed client assertion_ to authenticate to the OpenAIRE AAI server in order to obtain the access token for the OpenAIRE APIs. The client assertion is a JWT that must be signed with RSASSA using SHA-256 hash algorithm. The OpenAIRE AAI server validates the client assertion using the public key that you have provided upon the service registration.  [Continue reading for the Advanced Authentication](#advanced-service-authentication-and-registration).
+
+:::info
+The Advanced Authentication method allows the OpenAIRE AAI server to verify that the client authentication request at the token endpoint was signed by your service and not altered in any way. This is more computation intensive compared to the Basic Authentication but it ensures non-repudiation. On the other hand, the Basic Authentication is more lightweight and easy to deploy but it does not provide signature verification, and there is always a possibility of the Client ID/secret credentials being stolen. Note that tThe Advanced authentication method gives a higher level of security to the process as long as it is used correctly, i.e. when the signed JWT has a short duration. When the duration of the JWT is long, the process is no different from the basic one.
+:::
+
+### Basic service authentication and registration
+
+To have access to the following functionalities you need to login to OpenAIRE. In case you are not already a member you will need to register first and provide your [Personal information](https://develop.openaire.eu/personal-info).
+
+:::info New!
+The registration process has been updated! In order to visit the Personal Token and Registered Services functionalities you need to fill in the Personal Information form available [here](https://develop.openaire.eu/personal-info). This update will not affect the operation of your existing services. However, if you want to register a new service or access/modify an existing one, you will need to provide your personal information first.
+:::
+
+For the **Basic Authentication** method the OpenAIRE AAI server generates a pair of _Client ID_ and _Client Secret_ for your service upon its registration. The service uses the client id and client secret to obtain the access token for the OpenAIRE APIs. The OpenAIRE AAI server checks whether the client id and client secret sent is valid.
+
+#### How to register your service
+
+To register your service you need to:
+
+1.  Go to your [Registered Services](https://develop.openaire.eu/apis) page and click the **\+ New Service** button.
+2.  Provide the mandatory information for your service.
+3.  Select the **Basic** Security level.
+4.  Click the **Create** button.
+
+Once your service is created, the _Client ID_ and _Client Secret_ will appear on your screen. Click "OK" and your new service will be appear in the list of your [Registered Services](https://develop.openaire.eu/apis) page.
+
+#### How to make a request
+
+##### Step 1. Request for an access token
+
+To make an access token request use the _Client ID_ and _Client Secret_ of your service.
+```js
+curl -u {CLIENT_ID}:{CLIENT_SECRET} \
+-X POST 'https://aai.openaire.eu/oidc/token' \
+-d 'grant_type=client_credentials'
+```
+
+where **{CLIENT_ID}** and **{CLIENT_SECRET}** are the _Client ID_ and _Client Secret_ assigned to your service upon registration.
+
+The response is:
+```json
+{
+	"access_token": ...,
+	"token_type": "Bearer",
+	"expires_in": ...
+}
+```
+
+Store the access token confidentially on the service side.
+
+##### Step 2. Make a request
+
+To access the OpenAIRE APIs send the access token returned in **Step 1**.
+```js
+GET https://api.openaire.eu/{resourceServicePath}
+Authorization: Bearer {ACCESS_TOKEN}
+```
+
+### Advanced service authentication and registration
+
+
+To have access to the following functionalities you need to login to OpenAIRE. In case you are not already a member you will need to register first and provide your [Personal information](https://develop.openaire.eu/personal-info).
+
+:::info New! 
+The registration process has been updated! In order to visit the Personal Token and Registered Services functionalities you need to fill in the Personal Information form available [here](https://develop.openaire.eu/personal-info). This update will not affect the operation of your existing services. However, if you want to register a new service or access/modify an existing one, you will need to provide your personal information first.

+For the **Advanced Authentication** method your service does not send a client secret but it uses a _self signed client assertion_ to obtain the access token for the OpenAIRE APIs. The client assertion is a JWT that must be signed with RSASSA using SHA-256 hash algorithm. The OpenAIRE AAI server validates the client assertion using the public key that you have provided upon the service registration.
+
+#### Prepare to register your service
+
+Before you register your service you need to prepare a pair of a private key and a public key on your side.
+
+:::info
+We accept keys signed with RSASSA using SHA-256 hash algorithm.
+:::
+
+To create the key pair you have the following options:
+
+* Use OpenAIRE authorization server built in tool. You can access the service here: [https://aai.openaire.eu/oidc/generate-oidc-keystore](https://aai.openaire.eu/oidc/generate-oidc-keystore).  
+    The response is your **Public and Private Keypair** and has the following format:
+    ```json
+    { 
+    	"p" : ...,
+    	"kty" : "RSA",
+    	"q" : ...,
+    	"d" : ...,
+    	"e" : "AQAB",
+    	"kid" : ...,
+    	"qi" : ..., 
+    	"dp" : ..., 
+    	"alg" : "RS256",
+    	"dq" : ...,
+    	"n" : ....
+    }
+    ```
+
+    Use the public key parameters (kty, e, kid, alg, n) to create your **Public Key** in the following format:
+    ```json
+    {
+    	"kty": "RSA",
+    	"e": "AQAB",
+    	"kid": ...,
+    	"alg": "RS256",
+    	"n": ...
+    }
+    ```
+
+:::info
+Store both the **Public and Private keypair** and the **Public key**. You will need them to register your service.
+:::
+
+:::caution
+Store the **Public and Private keypair** confidentially on the service side.
+:::
+
+* Use openssl and then convert the keys to jwk format using PEM to JWK scripts, such as [https://github.com/danedmunds/pem-to-jwk](https://github.com/danedmunds/pem-to-jwk). Alternatively, the client application can read the key pair in PEM format and then convert them, using JWK libraries. Use the public key parameters (kty, e, kid, alg, n) to the service registration.
+
+:::info
+You can also provide a public key in JWK format that can be accessed using a link.
+:::
+
+#### How to register your service
+
+To register your service you need to:
+
+1.  Go to your [Registered Services](https://develop.openaire.eu/apis) page and click the **\+ New Service** button.
+2.  Provide the mandatory information for your service.
+3.  Select the **Advanced** Security level.
+4.  Use the public key parameters (kty, e, kid, alg, n) you previously produced to declare your **"Public Key"** **"By value"** in the following format:
+    ```json
+    {
+    	"kty": "RSA",
+    	"e": "AQAB",
+    	"kid": ...,
+    	"alg": "RS256",
+    	"n": ...
+    }
+    ```
+    **\- OR -**
+    
+    If your service has a public key in JWK format that can be accessed using a link, you can set **“Public Key”** to **“By URL”**.
+    
+5.  Click the **Create** button.
+
+Once your service is created it will appear in the list of your [Registered Services](https://develop.openaire.eu/apis) page, with the **Service Id** that was automatically assigned to it by the AAI OpenAIRE service.
+
+#### How to make a request
+
+##### Step 1. Create and sign a JWT
+
+Your service must create and sign a JWT and include it in the request to token endpoint as described in the [OpenID Connect Core 1.0, 9. Client Authentication](https://openid.net/specs/openid-connect-core-1_0.html#ClientAuthentication).
+
+To create a JWT you can use [https://mkjose.org/](https://mkjose.org/). To do so you need to create a **payload** that should contain the following claims:
+
+```json
+{
+	"iss": "{SERVICE_ID}",
+	"sub": "{SERVICE_ID}",
+	"aud": "https://aai.openaire.eu/oidc/token",
+	"jti": "{RANDOM_STRING}",
+	"exp": {EXPIRATION_TIME_OF_SIGNED_JWT}                            
+}
+```
+
+* **iss**, _(required)_ the “issuer” claim identifies the principal that issued the JWT. The value is the **Service Id** that was created when you registered your service.
+* **sub**, _(required)_ the “subject” claim identifies the principal that is the subject of the JWT. The value is the **Service Id** that was created when you registered your service.
+* aud, _(required)_ the “audience” claim identifies the recipients that the JWT is intended for. The value is **https://aai.openaire.eu/oidc/token**>.
+* **jti**, _(required)_ The “JWT ID” claim provides a unique identifier for the JWT. The value is a random string.
+* **exp**, _(required)_ the “expiration time” claim identifies the expiration time on or after which the JWT **MUST NOT** be accepted for processing. The value is a timestamp in **epoch format**.
+
+Fill in the payload in the form available at [https://mkjose.org/](https://mkjose.org/), select the Signing Algorithm to be **RS256 using SHA-256** and paste the **Public and Private Keypair** previously created.
+
+To check your JWT you can go to [https://jwt.io/](https://jwt.io/). The **header** should contain the following claims:
+```json
+{
+	"alg": "RS256",
+	"kid": ...
+}
+```
+
+where **kid** is the one of your **Public and Private Keypair** you used to sign the JWT in **Step 1**.
+
+:::caution
+Store the signed key confidentially on the service side. You will need it in Step 2.
+:::
+
+##### Step 2. Request for an access token
+
+To make an access token request use the _signed JWT_ that you created in **Step 1**. The OpenAIRE AAI server will check if the signed JWT is valid using the public key that you declared in the **"How to register your service"** process.
+```js
+	curl -k -X POST "https://aai.openaire.eu/oidc/token" \
+	-d "grant_type=client_credentials" \
+	-d "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer" \
+	-d "client_assertion={signedJWT}"
+```
+where **{signedJWT}** is the signed JWT created in **Step 1**.
+
+The response is:
+```json
+{
+	"access_token": {ACCESS_TOKEN}
+	"token_type":"Bearer",
+	"expires_in": ...,
+	"scope":"openid"
+}
+```
+
+Store the access token confidentially on the service side.
+
+##### Step 3. Make a request
+
+To access the OpenAIRE APIs send the access token returned in **Step 2**.
+```js
+	GET https://test.openaire.eu/{resourceServicePath}
+	Authorization: Bearer {ACCESS_TOKEN}
+```

+# Broker API
+
+
+## Introduction
+
+The Broker Service is available to use via the OpenAIRE Content Provider Dashboard. Thanks to the Broker, repositories, publishers or aggregators can exchange metadata and enrich their local metadata collection by subscribing to notifications of different types. The Broker is able to notify providers when the OpenAIRE Graph contains information that is not available in the original collection of the data source. In particular, the data source manager can subscribe via the [Content Provider Dashboard](https://provide.openaire.eu) and be notified about:
+
+*   Additional PIDs of its publications (e.g. DOIs)
+*   Links to projects
+*   ORCID that can be associated to an author of datasource publications
+*   Links to Open Access versions
+*   Additional classification subjects (e.g. subjects from standard schemes like ACM, JEL and DDC)
+*   Abstracts identified in duplicate publications
+*   Missing publication dates
+
+All Repository managers approaching the Content Provider Dashboard will be offered the possibility to preview a set of enrichments relative to their repository that OpenAIRE can derive from the Graph. More specifically, enrichments will be organized into categories named topics and representing the different types of enrichments OpenAIRE can build. For each topic the preview consists of 100 “enrichment events”, a subset of all the possible enrichments pertinent to a given repository in the OpenAIRE Graph, that the user can explore by applying filters on different criteria and the total number of events that can be potentially built is highlighted in the UI. Repository managers can create subscriptions for specific topics and that include the filtering criteria they used to analyze the enrichments preview, or can subscribe to all the available topics with no restrictions at once. Once the repository manager creates a subscription, the algorithm analyzing the OpenAIRE Graph will produce the full set of enrichments for the manager's repository, possibly far beyond the 100 enrichments available in the preview. The enrichments will be made available as notifications in a dedicated section in the Content Provider Dashboard UI to be further checked as well as through the broker service API for programmatic access. Notifications will be sent to subscribers every time the OpenAIRE Graph will be updated and analyzed to derive the enrichments.
+
+## Usage Example
+
+The following commands indicate how the broker API documented at [api.openaire.eu/broker](https://api.openaire.eu/broker/swagger-ui/index.html) can be used to access the set of enrichments:
+
+1.  Get the list of subscriptions for a given subscriber, e.g.
+    
+    ```js
+    curl -X GET --header 'Accept: application/json' 'https://api.openaire.eu/broker/subscriptions?email=[subscriber_email]'
+    ```
+    
+2.  Extract the subscription ID and use it to access the 1st page of enrichment notification records
+    
+    ```js
+    curl -X GET --header 'Accept: application/json' 'https://api.openaire.eu/broker/scroll/notifications/bySubscriptionId/[sub-1234]'
+    ```
+    
+3.  Extract the scroll ID from the response to request subsequent pages
+    
+    ```js
+    curl -X GET --header 'Accept: application/json' 'https://api.openaire.eu/broker/scroll/notifications/[scroll_id]'
+    ```    
+
+To simplify accessing the enrichment notification records, please check the OpenAIRE broker cmdline client available on [GitHub](https://github.com/openaire/broker-cmdline-client).

+# Response metadata format
+
+In this page, we elaborate on the metadata response format, as well as response headers and errors. 
+
+## Main response
+
+The OpenAIRE Search API supports the following types of response formats: 
+
+* XML
+* JSON
+* CSV
+* TSV 
+
+In the next paragraphs, we elaborate on the respective metadata formats. 
+
+### XML/JSON
+
+The default format of delivered records is oaf (OpenAIRE Format - current version 1.0):
+
+* XML schema: https://www.openaire.eu/schema/1.0/oaf-1.0.xsd
+* Documentation: https://www.openaire.eu/schema/1.0/doc/oaf-1.0.html
+
+For the list of changes [click here](https://www.openaire.eu/openaire-xml-schema-change-announcement).
+
+Note that latest versions of the XML schema and documentation are also available at the following permanent links:
+
+* XML schema: https://www.openaire.eu/schema/latest/oaf.xsd
+* Documentation: https://www.openaire.eu/schema/latest/doc/oaf.html
+
+Older versions:

+
+
+### CSV/TSV
+
+The API returns in comma-separated files (CSV) or tab-separated files (TSV) the following fields:
+
+* Title
+* AUthors
+* Publicatioy year
+* DOI
+* Download from
+* Publication type
+* Journal
+* Funder
+* Project name (GA Number)
+* Access
+
+## Headers
+
+|  Name   |  Description   |
+| --- | --- |
+| x-ratelimit-limit | The maximum number of requests allowed for the client in one time window. |
+| x-ratelimit-used | The number of requests already made by the client in the current time window. |

+# Search API
+
+The Search API allows developers to access metadata records of the OpenAIRE Graph by performing queries over research products (i.e., publications, data, software, other research products), and projects. 
+
+The API is intended for metadata discovery and exploration only, hence it does not provide access to the whole information space: the number of total results returned by one query is limited to 10,000. 
+
+For accessing the whole graph, developers are encouraged to use the [OpenAIRE full Graph dataset](../../downloads/full-graph).

+## Versioning
+
+Our versioning policy follows the [Semantic Versioning specification](https://semver.org/).
+In our case, given a version `MAJOR.MINOR.PATCH`, we increment the:
+
+* `MAJOR` version when the data model of the Graph changes
+* `MINOR` version when the pipeline (e.g., different deduplication method, different implementation for an enrichment process) or major data sources change
+* `PATCH` version when the graph data are updated
+
+## Changelog
+
+This section documents all notable changes for each graph version.

+
+#### Added
+
+- The scientific products aggregated increased by ~5Mi records (+1.6%)
+
+#### Changed
+
+- A refined version of the deduplication strategy allowed to catch more duplicates among the scientific products, implying 
+  a decrease of their total number of ~3.2Mi (-1.35%). More details about the deduplication algorithm are available [here](graph-production-workflow/deduplication/research-products).
+- Updated Crossref publications to include contents until November 2023

+# Data model
+
+The OpenAIRE Graph comprises several types of [entities](../category/entities) and [relationships](/category/relationships) among them.
+
+The latest version of the JSON schema can be found on the [Downloads](../downloads/full-graph) section.

+The figure above, presents the graph's data model. 
+Its main entities are described in brief below:
+
+* [Research products](./entities/research-product) represent the outcomes (or products) of research activities.
+* [Data sources](./entities/data-source) are the sources from which the metadata of graph objects are collected. 
+* [Organizations](./entities/organization) correspond to companies or research institutions involved in projects,

+# Communities
+
+Research communities and research initiatives are intended as groups of people with a common research intent and can be of two types: ​research initiatives or ​research communities​:
+
+* Research initiatives are intended to capture a view of the information space that is "research impact"-oriented, i.e. all products generated due to my research initiative;
+* Research communities the latter “research activity” oriented, i.e. all products that may be of interest or related to my research initiative.
+
+For example, the organizations supporting a research infrastructure fall in the first category, while the researchers involved in a discipline fall in the second.

+# Data sources
+
+OpenAIRE entity instances are created out of data collected from various data sources of different kinds, such as publication repositories, dataset archives, CRIS systems, funder databases, etc. Data sources export information packages (e.g., XML records, HTTP responses, RDF data, JSON) that may contain information on one or more of such entities and possibly relationships between them. 
+
+For example, a metadata record about a project carries information for the creation of a Project entity and its participants (as Organization entities). It is important, once each piece of information is extracted from such packages and inserted into the OpenAIRE information space as an entity, for such pieces to keep provenance information relative to the originating data source. This is to give visibility to the data source, but also to enable the reconstruction of the very same piece of information if problems arise.

+Main date of the research product: typically the publication or issued date. In case of a research product with different versions with different dates, the date of the research product is selected as the most frequent well-formatted date. If not available, then the most recent and complete date among those that are well-formatted. For statistics, the year is extracted and the research product is counted only among the research products of that year. Example: Pre-print date: 2019-02-03, Article date provided by repository: 2020-02, Article date provided by Crossref: 2020, OpenAIRE will set as date 2019-02-03, because it’s the most recent among the complete and well-formed dates. If then the repository updates the metadata and set a complete date (e.g. 2020-02-12), then this will be the new date for the research product because it becomes the most recent most complete date. However, if OpenAIRE then collects the pre-print from another repository with date 2019-02-03, then this will be the “winning date” because it becomes the most frequent well-formatted date.

+# PIDs and identifiers
+
+One of the challenges towards the stability of the contents in the OpenAIRE Graph consists of making its identifiers and records stable over time.
+The barriers to this scenario are many, as the Graph keeps a map of data sources that is subject to constant variations: records in repositories vary in content,
+original IDs, and PIDs, may disappear or reappear, and the same holds for the repository or the metadata collection it exposes.
+Not only, but the mappings applied to the original contents may also change and improve over time to catch up with the changes in the input records.
+
+## PID Authorities
+
+One of the fronts regards the attribution of the identity to the objects populating the graph. The basic idea is to build the identifiers of the objects in the graph from the PIDs available in some authoritative sources while considering all the other sources as by definition “unstable”. Examples of authoritative sources are Crossref and DataCite. Examples of non-authoritative ones are institutional repositories, aggregators, etc. PIDs from the authoritative sources would form the stable OpenAIRE ID skeleton of the Graph, precisely because they are immutable by construction.
+
+Such a policy defines a list of data sources that are considered authoritative for a specific type of PID they provide, whose effect is twofold:
+* OpenAIRE IDs depend on persistent IDs when they are provided by the authority responsible to create them;
+* PIDs are included in the graph according to a tight criterion: the PID Types declared in the table below are considered to be mapped as PIDs only when they are collected from the relative PID authority data source.
+
+| PID Type  | Authority                                                                                           |
+|-----------|-----------------------------------------------------------------------------------------------------|
+| doi       | [Crossref](https://www.crossref.org), [Datacite](https://datacite.org)                              |
+| pmc, pmid | [Europe PubMed Central](https://europepmc.org/), [PubMed Central](https://www.ncbi.nlm.nih.gov/pmc) |
+| arXiv     | [arXiv.org e-Print Archive](https://arxiv.org/)                                                     |
+| uniprot   | [Protein Data Bank](http://www.pdb.org/)                                                            |
+| ena       | [Protein Data Bank](http://www.pdb.org/)                                                            |
+| pdb       | [Protein Data Bank](http://www.pdb.org/)                                                            |
+
+
+There is an exception though: Handle(s) are minted by several repositories; as listing them all would not be a viable option, to avoid losing them as PIDs, Handles bypass the PID authority filtering rule.
+In all other cases, PIDs are be included in the graph as alternate Identifiers.
+
+## Delegated authorities
+
+When a record is aggregated from multiple sources considered authoritative for minting specific PIDs, different mappings could be applied to them and, depending on the case,
+this could result in inconsistencies in the attribution of the field values.
+To overcome the issue, the intuition is to include such records only once in the graph. To do so, the concept of "delegated authorities" defines a list of datasources that
+assigns PIDs to their scientific products from a given PID minter.
+
+This "selection" can be performed when the entities in the graph sharing the same identifier are grouped together. The list of the delegated authorities currently includes
+
+| Datasource delegated                 | Datasource delegating            | Pid Type  |
+|--------------------------------------|----------------------------------|-----------|
+| [Zenodo](https://zenodo.org)         | [Datacite](https://datacite.org) | doi       |
+| [RoHub](https://reliance.rohub.org/) | [W3ID](https://w3id.org/)        | w3id      |
+
+
+## Identifiers in the Graph
+
+OpenAIRE assigns internal identifiers for each object it collects.
+By default, the internal identifier is generated as `sourcePrefix::md5(localId)` where:
+
+* `sourcePrefix` is a namespace prefix of 12 chars assigned to the data source at registration time
+* `localΙd` is the identifier assigned to the object by the data source
+
+After years of operation, we can say that:
+
+* `localId` are generally unstable
+* objects can disappear from sources
+* PIDs provided by sources that are not PID agencies (authoritative sources for a specific type of PID) are often wrong (e.g. pre-print with the DOI of the published version, DOIs with typos)
+
+Therefore, when the record is collected from an authoritative source:
+
+* the identity of the record is forged using the PID, like `pidTypePrefix::md5(lowercase(doi))`
+* the PID is added in a `pid` element of the data model
+
+When the record is collected from a source which is not authoritative for any type of PID:
+* the identity of the record is forged as usual using the local identifier
+* the PID, if available, is added as `alternateIdentifier`
+
+Currently, the following data sources are used as "PID authorities":
+
+| PID Type  | Prefix (12 chars)      | Authority                             	 |
+|-----------|------------------------|-------------------------------------------|
+| doi       | `doi_________`      	  | Crossref, Datacite, Zenodo            	 |
+| pmc       | `pmc_________`      	  | Europe PubMed Central, PubMed Central 	 |
+| pmid      | `pmid________`      	  | Europe PubMed Central, PubMed Central 	 |
+| arXiv     | `arXiv_______`      	  | arXiv.org e-Print Archive             	 |
+| handle    | `handle______`      	  | any repository                        	 |
+| ena       | `ena_________`      	  | EMBL-EBI                            	 |
+| pdb       | `pdb_________`      	  | EMBL-EBI                            	 |
+| uniprot   | `uniprot_____`      	  | EMBL-EBI                            	 |
+
+OpenAIRE also perform duplicate identification (see the [dedicated section for details](/graph-production-workflow/deduplication)).
+All duplicates are **merged** together in a **representative record** which must be assigned a dedicated OpenAIRE identifier (i.e. it cannot have the identifier of one of the aggregated record).
