  • How we’re doing it! The Europeana Search API 19 million + metadata records The Europeana Linked Open Data Pilot 3.5 million metadata records Mash-up with other services and APIs
  • About the API OpenSearch standard Freetext search Freetext index and field specific indices queryable Including semantic enrichments Spatial and time interval queries RSS, JSON and ESE-XML responses!\\ API documentation at http://europeanalabs.eu/wiki/EuropeanaOpenSearchAPI
  • Linked Data Pilot Dereferencable URIs Data dumps 3.5 million records RDF modelled on EDM 3.5 million metadata records
  • The Content 19 million+ metadata records With links to digital objects Books, letters, newspapers, photos, museum artefacts, etc. From 1500+ data providers Libraries, Archives, Museums In all European languages, from all EU countries and more
  • The records ESE-XML format, see the specs in the documentation! Dublin Core + Europeana elements Semantic enrichments: Places, Periods, Persons, Subjects Links to the landing page and sometimes to the digital objects Rights information for the digital objects
  • The records II Data in RDF Otherwise same type of content as the API responses in ESE
  • Any questions? This poster by an unknown artist is courtesy of the Municipal Library of Lyon The work is in the public domain The images in slides 2-5 are taken from the Europeana Strategic Plan
