### coverage
_Type: String • Cardinality: MANY_
### dateofcollection
_Type: String • Cardinality: ONE_
When OpenAIRE collected the record the last time.
```json
"dateofcollection": "2021-06-09T11:37:56.248Z"
```
### description
_Type: String • Cardinality: MANY_
A brief description of the resource and the context in which the resource was created.
```json
"description": [
"Open science partnerships (OSPs) are one mechanism to reverse declining efficiency. OSPs are public-private partnerships that openly share publications, data and materials.",
"There is growing concern that the innovation system's ability to create wealth and attain social benefit is declining in effectiveness. This article explores the reasons for this decline and suggests a structure, the open science partnership, as one mechanism through which to slow down or reverse this decline.",
"The article examines the empirical literature of the last century to document the decline. This literature suggests that the cost of research and innovation is increasing exponentially, that researcher productivity is declining, and, third, that these two phenomena have led to an overall flat or declining level of innovation productivity.",

### embargoenddate
_Type: String • Cardinality: ONE_
Date when the embargo ends and this result turns Open Access.
currently, the following two types of indicators are supported: [impact indicators](/graph-production-workflow/indicators-ingestion/impact-indicators) and [usage statistics indicators](/graph-production-workflow/indicators-ingestion/usage-counts).
Specific materialization or version of the result. For example, you can have one result with three instances: one is the pre-print, one is the post-print, one is the published version.
Persistent identifiers of the result. See also the [OpenAIRE entity identifier and PID mapping policy](../pids-and-identifiers) to learn more.
```json
"pid": [
{
"scheme": "pmc",
"value": "PMC8024784"
},
{
"scheme": "doi",
"value": "10.1016/j.respol.2021.104226"
},
...
]
```
### publicationdate
_Type: String • Cardinality: ONE_
Main date of the research product: typically the publication or issued date. In case of a research result with different versions with different dates, the date of the result 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 result is counted only among the result 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 result 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.
```json
"publicationdate": "2021-03-18"
```
### publisher
_Type: String • Cardinality: ONE_
The name of the entity that holds, archives, publishes prints, distributes, releases, issues, or produces the resource.
```json
"publisher": "Elsevier, North-Holland Pub. Co"
```
### source
_Type: String • Cardinality: MANY_
A related resource from which the described resource is derived. See definition of Dublin Core field [dc:source](https://www.dublincore.org/specifications/dublin-core/dcmi-terms/elements11/source).
Subject, keyword, classification code, or key phrase describing the resource.
```json
"subjects": [
{
"provenance": {
"provenance": "Harvested",
"trust": "0.9"
},
"subject": {
"scheme": "keyword",
"value": "Open science"
}
},
...
