Technical Requirements

Any organization that has digitized and documented cultural content on an online platform can provide its collections to as long as their content meets some basic specifications.

More specifically:

  • The harvesting of metadata will be done through the OAI-PMH protocol, which is a very popular metadata delivery protocol now supported virtually by all repositories and digital libraries.
  • Metadata should be made available via OAI-PMH as XML, preferably in one of the following formats: ESE standard proposed by the Europeana library or the EDM standard, which is the evolution of ESE.
  • From the Dublin Core fields (basic Metadata Element Set or DCMI Metadata Terms Set), you should at least have the value of the core fields: dc: title, dc: type, dc: subject, dc (dc: description or dcterms: created or dcterms: temporal), and dcterms: spatial, and dc: description or dc: tableOfContents or dcterms: abstract, : creator or dc: contributor)
  • In addition, two (2) URLs should be provided within the ESE or EDM metadata: the web page of the record page (in ese: isShownAt / edm: isShownAt or alternatively in dc: identifier), and the thumbnail image field ese: object / edm: object). It is recommended that you also provide the web address of the original digital file (in ese: isShownBy / edm: isShownBy) in order to be able to directly link to your digital file URL.
  • In ESE or EDM metadata, a license for the use of digital content should be specified in ese: rights (or edm: rights) field: either one of the creative commons licenses ( or "Europeana | Rights Reserved - Free Access "(
  • In ESE or EDM metadata, in ese: type (or edm: type) field, the Europeana type should be entered (TEXT, IMAGE, AUDIO, VIDEO, 3D)

If the OAI-PMH of your repository does not support ESE or EDM, it is also possible to use the default type OAI-DC of the OAI-PMH protocol or one of the Qualified DC (QDC), HEAL, MODS, or DC-DS-XML, subject to agreement and subject to certain conditions being met (thumbnail availability or sourcing them from the record pages, also licensing digital content clearly).
