Metadata Requirements

ESDN harvests and normalizes metadata for contribution to DPLA. We receive metadata in a variety of formats (including Dublin Core and MODS), usually through an OAI-PMH feed. If your institution’s metadata is not shareable via OAI-PMH, we will work with you to determine an alternative solution.

ESDN brings together the contributed metadata from our partner institutions and maps it to a set of MODS elements for passing on to DPLA. Those elements have been mapped to properties in the DPLA Metadata Application Profile, which underpins services provided by the DPLA such as the DPLA API and portal. Please consult DPLA’s An Introduction to the DPLA Metadata Model for additional information.

In order to contribute records to DPLA, your metadata must contain two descriptive fields: Title and Rights. A number of additional descriptive fields are recommended and/or optional. The more complete and accurate your records are, the more likely they are to be discovered and used through DPLA.

In addition to those descriptive fields, ESDN is required to submit with each record a link back to the metadata record in your local context as well as a link to a thumbnail ‘preview’ of the object (where available). A data provider field containing the name of the “owning institution” of each object is also submitted with each record.
