<p>Openaire XML Schema has been changed! Please <ahref="https://www.openaire.eu/openaire-xml-schema-change-announcement"target="_blank">click here</a> to learn more!</p>
<p>Currently the OAI-PMH publisher is <strong>not</strong> supporting incremental harvesting. <br>
Although the usage of the OAI parameters 'from' and 'until' is handled by the OAI publisher, the datestamps of metadata records are updated about every week.<br>
We apologise for any inconvenience this may cause to harvesters,<br>

<p> OAI-PMH is a standard protocol for metadata publishing and harvesting. For details on the OAI-PMH protocol please refer to the official documentation at <ahref="http://www.openarchives.org/OAI/openarchivesprotocol.html"target="_blank">http://www.openarchives.org/OAI/openarchivesprotocol.html</a></p>
<p> The OpenAIRE OAI-PMH endpoint is <ahref="http://api.openaire.eu/oai_pmh"target="_blank">http://api.openaire.eu/oai_pmh</a><br>
For information about the endpoint check <ahref="http://api.openaire.eu/oai_pmh?verb=Identify"target="_blank">http://api.openaire.eu/oai_pmh?verb=Identify</a><br>
The updated list of OAI sets is always available at <ahref="http://api.openaire.eu/oai_pmh?verb=ListSets"target="_blank">http://api.openaire.eu/oai_pmh?verb=ListSets</a>

For the list of available metadata prefixes, check: <ahref="http://api.openaire.eu/oai_pmh?verb=ListMetadataFormats"target="_blank">http://api.openaire.eu/oai_pmh?verb=ListMetadataFormats</a>. <br>
Note that records will always be available in the OpenAIRE format (schema, documentation). The availability of records in oai_dc and oai_datacite depends on the typology of records.<br>
Publications are avaialble in <code>oai_dc</code> according to the <strong>OpenAIRE3.0 guidelines</strong> for literature repositories. <br>
Datasets are available in <code>oai_datacite</code> according to the <strong>OpenAIRE2.0 guidelines</strong> for data archives. <br>
