CRIS interoperability

The capacity of CRIS systems to exchange data with each other and with adjacent systems (repositories, funders, publishers, aggregators) through shared data models, schemas, protocols, and persistent identifiers — most prominently CERIF, OAI-PMH, the OpenAIRE Guidelines, and PID-based joins.

Examples

Worked examples

  • Is an instance

    A Pure deployment exporting CERIF-XML over OAI-PMH for OpenAIRE harvesting.

  • Is an instance

    A national funder's project database joinable to institutional CRIS records via Crossref Funder ID and RAiD.

Counter-examples

Looks similar, but isn't

  • Not an instance

    Manually pasting data between two CRIS systems is not interoperability.

  • Not an instance

    Two separate CRIS installations that share no schema or protocol are not interoperable.

Editorial commentary

CRIS interoperability is the capacity of Current Research Information Systems to exchange data with each other and with adjacent systems — repositories, funders, publishers, aggregators — without manual re-entry. It rests on three pillars, tracked as a coordinated technical and policy programme by euroCRIS and the COAR/euroCRIS CRIS-IR working group: shared models (what entities and relationships are exchanged), shared protocols (how the exchange happens), and shared identifiers (how the entities being exchanged are joined unambiguously across systems).

The three pillars in practice

The model pillar is CERIF (Common European Research Information Format), whose care and custody the European Union handed to euroCRIS; it defines standard entity types (person, organisation unit, project, publication, funding) and the relationships between them. The protocol pillar has historically meant OAI-PMH for CERIF-XML harvesting, with ResourceSync for incremental synchronisation and REST-based APIs (as used by systems like Pure) increasingly supplementing it. The identifier pillar is what actually lets records minted in independent systems be joined without ambiguity: ORCID iD for people, ROR for organisations, DOI for outputs, RAiD for projects, and Crossref Funder ID for funders — see identifier crosswalk for how these get connected when a single record needs more than one.

Where the pillars are operationalised

The OpenAIRE Guidelines for CRIS Managers turn the three pillars into a concrete, versioned CERIF-XML export profile that a CRIS can be tested against — a system’s practical interoperability is usually demonstrated by whether it can produce a valid Guidelines-conformant export via OAI-PMH, not just by claiming CERIF support in principle. The Guidelines are actively maintained by euroCRIS and OpenAIRE and revised periodically; treat any specific version number as a point-in-time fact to re-check against euroCRIS’s own documentation rather than a fixed standard.
