These guidelines describe the CERIF-XML profile for CRIS managers to be compatible with OpenAIRE.


The Guidelines provide orientation for CRIS managers to expose their metadata in a way that is compatible with the OpenAIRE infrastructure. By implementing the Guidelines, CRIS managers support the inclusion and therefore the reuse of metadata in their systems within the OpenAIRE infrastructure. For developers of CRIS platforms, the Guidelines provide guidance to add supportive functionalities for CRIS managers and users. Exchange of information between individual CRIS systems and the OpenAIRE infrastructure is an example of point-to-point data exchange between CRIS systems, since the OpenAIRE infrastructure is itself a CRIS system.


CERIF (Common European Research Information Format) is a standard data model for research information and a recommendation by the European Union to Member States. The care and custody of CERIF was handed over by the European Union to euroCRIS (, a non-for-profit organisation dedicated to the interoperability of Research Information Systems (CRISs). In addition to a domain model and a formal data model, CERIF includes a mechanism to construct XML profiles (specialized subsets) for specific information interchange scenarios. The OpenAIRE profile of CERIF supports harvesting and importing metadata from CRIS systems.

Compliance to the FAIR Principles

The compliance of these Guidelines to the FAIR Principles has been studied and is documented in a separate report that will be made available on Zenodo.
