Use of OAI-PMH

OpenAIRE uses the OAI-PMH v2.0 protocol for harvesting dataset metadata.

Metadata Format

OpenAIRE expects metadata to be encoded in the DataCite metadata format (metadataPrefix oai_datacite) . For information on how to use the individual DataCite properties, please refer to Application Profile Overview.


A specific OAI-Set at the local repository should be configured to select records relevant to OpenAIRE for harvesting. The following characteristics of the set are recommended:

setName setSpec
OpenAIRE openaire_data


A harvester only uses the setSpec value to perform selective harvesting. The letters of the setSpec must be in small caps.

Set content

The specific content of the openaire_data set is to be determined at the local repository. OpenAIRE will harvest all datasets from the openaire_data set.
