+##DHP-Aggregation
+
+This module defines a set of oozie workflows for the **collection** and **transformation** of metadata records.
+
+Both workflows interact with the Metadata Store Manager (MdSM) to handle the logical transactions required to ensure
+the consistency of the read/write operations on the data as the MdSM in fact keeps track of the logical-physical mapping
+of each MDStore.
+
+It defines [mappings](mappings.md) for transformation of different datasource (See mapping section).

+DHP-Aggregations contains different mappings from original data format into OAF Data Format, 
+which converge in the graph in different ways:

+- Via Action Manager
+- Direct in the MdStore on Hadoop

+#Pubmed Mapping
+This section describes the mapping implemented for [MEDLINE/PubMed](https://pubmed.ncbi.nlm.nih.gov/).
+
+Collection
+---------
+The native data is collected from [ftp baseline](https://ftp.ncbi.nlm.nih.gov/pubmed/baseline/) containing XML with 
+the following [shcema](https://www.nlm.nih.gov/bsd/licensee/elements_descriptions.html) 
+
+
+Parsing
+-------
+The resposible class of parsing is [PMParser](./scaladocs/#eu.dnetlib.dhp.sx.bio.pubmed.PMParser) that generates 
+an intermediate mapping of PubMed Article defined [here](/apidocs/eu/dnetlib/dhp/sx/bio/pubmed/package-summary.html)
+
+
+Mapping
+-------
+
+The table below describes the mapping from the XML Native to the OAF mapping
+
+
+
+
+
+| Xpath Source | Oaf Field  | Notes       |
+| ----------- | ----------- | ----------- |
+| //PMID      | pid         | classid = classname = pmid
+|  | **Instance Mapping** |      |
+|//PublicationType | InstanceType  | If the article contains the typology **Journal Article** then we apply this type else We have to find a terms that match the vocabulary otherwise we discard it
+|//PMID | instance/PID | Map the pmid also in the pid in the instance |
+| //ArticleId[./@IdType="doi"   | instance/alternateIdentifier  |classid = classname = doi
+|//PMID | instance/URL | prepend to the PMId the base url https://pubmed.ncbi.nlm.nih.gov/
+| //PubmedPubDate | instance/Dateofacceptance | apply the function GraphCleaningFunctions.cleanDate before assign it
+|  FOR ALL INSTANCE | CollectedFrom | datasourceName: *Europe PubMed Central* DatasourceId:   
+|  | **Journal Mapping** |      |
+|//Journal/PubDate| Journal/Conferencedate | map the date of the Journal
+|//Journal/Title| Journal/Name | |
+|//Journal/Volume| Journal/Vol | |
+|//Journal/ISSN| Journal/issPrinted | |
+|//Journal/Issue| Journal/Iss | |
+|  | **Publication Mapping** |      |
+| //PubmedPubDate | Dateofacceptance | apply the function GraphCleaningFunctions.cleanDate before assign it
+| //Title | title | with qualifier ModelConstants.MAIN_TITLE_QUALIFIER
+| //AbstractText | Description ||
+|//Language| Language| cleaning vocabulary -> dnet:languages
+|//DescriptorName| Subject | classId, className = keyword
+|  | **Author Mapping** |      |
+|//Author/LastName| author.Surname| |
+|//Author/ForeName| author.Forename| |
+|//Author/FullName| author.Forename| Concatenation of forname + lastName if exist |
+|FOR ALL AUTHOR | author.rank| sequential number starting from 1|
