We provide freely available metadata feeds in various formats and work with intermediaries to optimise dissemination of the collection.
- OAPEN provides daily metadata feeds in various formats (ONIX 3.0, MARC21, MARCXML, CSV) for libraries and their service providers.
- OAPEN works with the main library suppliers, such as ProQuest (Serial Solutions), ExLibris (Primo Central) and EBSCO Discovery Service. The publications are integrated in WorldCat (OCLC) and BASE; OAPEN acts as aggregator for Europeana.
- Libraries and aggregators can also harvest the metadata using the OAI harvesting protocol.
- OAPEN.org is optimised for search engines (using the site map) and is indexed by Google Scholar.
