How OpenAIRE uses persistent identifiers for discovery, enrichment, and linking of research results
Download as PPTX, PDF1 like718 views
OpenAIRE's e-infrastructure utilizes Persistent Identifiers (PIDs) to enhance the discovery, enrichment, and linking of various research outputs, including publications, datasets, and software. The organization's content acquisition policy accommodates both open and non-open access materials, aiming to ensure interoperability and support FAIR data principles through established standards. OpenAIRE extends existing PID types and maintains links between research products, authors, funders, and related identifiers to facilitate easier access and integration of research information.
How OpenAIRE uses persistent identifiers for discovery, enrichment, and linking of research results
- 1. @openaire_eu How OpenAIRE uses PIDs for discovery, enrichment, and linking of research results
- 3. Aggregation of Research Results by OpenAIRE Publications • Article • Preprint • Report • … Datasets • Dataset • Collection • Clinical Trials • … Software • Research Software • … Other Research Products • Service • Workflow • Interactive Resource • … Institutional/ publication repositories Journals/ publishers Data repositories Other Products repositories Software repositories
- 4. Objectives of OpenAIRE’s Aggregation Policy Content Acquisition Policy released 05-Oct-2018, https://doi.org/10.5281/zenodo.1446408
- 5. OpenAIRE accepts the metadata records of all scientific products whose structure respect the model and semantics as expressed by the OpenAIRE guidelines. This means that both Open Access and non-Open Access material will be included and links to other products will be resolved where this is possible (i.e. the provided PIDs have a resolver). as stated in the Content Acquisition Policy https://www.openaire.eu/data-aquisition-policy

- 8. ● to improve interoperability of metadata information exchange ● to support FAIR Data Principles ● by defining application profiles to describe different kinds of research products ● by re-using existing standards (Dublin Core, DataCite) ● by extending vocabularies when necessary, ○ e.g. for PID types OpenAIRE Guidelines Objectives
- 9. PIDs for the Resource Identifier 9 <datacite:identifier> identifierType="DOI"> https://dx.doi.org/10.17026/dans-zr6-atf9 </datacite:identifier> ● OpenAIRE extends DataCite’s list of PID identifier types: ○ ARK ○ DOI ○ Handle ○ PURL ○ URL ○ URN
- 10. (P)IDs for Alternative Identifiers of the Resource 10 ● other identifier(s) applied to the same resource, incl. local identifiers expressed in alternate Identifier Type: ○ ARK ○ arXiv ○ bibcode ○ DOI ○ EAN13 ○ ISSN ○ IGSN ○ ISTC ○ PMID ○ URN ○ ... <datacite:alternateIdentifier> alternateIdentifierType="URN"> urn:nbn:nl:ui:13-ef0u-oq </datacite:alternateIdentifier>
- 11. (P)IDs for Related Identifiers to the Resource 11 ● identifier(s) that are related to the registered resource, e.g. community-IDs incl. relation type, related metadata scheme & resource type, list of related Identifier Types includes e.g.: ○ ARK ○ arXiv ○ bibcode ○ DOI ○ EAN13 ○ ISSN ○ IGSN ○ ISTC ○ PMID ○ URN ○ ... <datacite:relatedIdentifier> relatedIdentifierType="DOI" relationType="isReferencedBy"> 10.1186/s12910-016-0120-6 </datacite:alternateIdentifier>
- 12. PIDs for Authors & Contributors 12 <datacite:creator> <datacite:creatorName>Wallentin, Carl‐Johan</datacite:creatorName> <datacite:nameIdentifier nameIdentifierScheme="ORCID" schemeURI=“http://orcid.org"> http://orcid.org/0000-0003-1983-9378 </datacite:nameIdentifier> </datacite:creator> ● OpenAIRE follows DataCite’s approach of an open list of name Identifiers, such as: ○ ORCID ○ ISNI
- 13. PIDs for Funders and Project Grants 13 <datacite:fundingReference> <datacite:funderName>European Commission</datacite:funderName> <fundingStream>H2020 Marie Skłodowska-Curie Actions</fundingStream> <datacite:funderIdentifier funderIdentifierType="Crossref Funder ID">10.13039/501100000780 </datacite:funderIdentifier> <datacite:awardNumber awardURI="http://cordis.europa.eu/project/..."> 660668 </datacite:awardNumber> <datacite:awardTitle>ACT against AMR</datacite:awardTitle> </datacite:fundingReference> ● to support linking of research products with related project(s) / funder(s) ● again an open list of funder Identifier types, such as: ○ Crossref Funder ○ ISNI ○ GRID
