3. Providing an open metadata
research graph of interlinked
scientific products, with Open
Access information, linked to
funding information and research
communities
The OpenAIRE research graph
Open
Complete
De-duplicated
Transparent
Participatory
Decentralized
Trusted

4. De-duplicated
More information about the de-duplication framework used by OpenAIRE can be found
searching on Zenodo for :
• “De-duplicating the OpenAIRE Scholarly Communication Big Graph” (poster)
• “GDup: De-Duplication of Scholarly Communication Big Graphs”
Metadata records
corresponding to equivalent
objects are merged

6. • Rely on quality scholarly
communication sources of
different kinds
Participatory
• Include solutions and content
from any interested and known
content provider in scholarly
communication
Institutional repositories
Aggregators
Data archives
Software repositories
Research infrastructure sources
Funder grant databases
Authors & Orgs entity registries
Publishers & journals

7. • Metadata in the graph includes provenance when harvested
and reliability indicators when obtained from mining
Transparent

8. • Preservation and ownership beyond OpenAIRE
Exchanged with other graph initiatives
Broker Service: Redistributed via subscription and
notification to contributing data sources
(provide.openaire.eu)
• Openly accessible via APIs
(develop.openaire.eu)
Decentralized

9. • Authors in the loop to enrich their ORCID record
• Validation of end-user ”claims”
Trusted (November 2019)
