Requirements of participation:

  • Active Regular Member or DPLA Affiliate Member contract

  • Willingness to allow metadata to be made accessible under a CC0 license through DPLA (see the TDL DPLA Metadata Guidelines for more information)

  • Staff to work in consultation with TDL staff to ensure appropriate metadata mapping of repository collections to the DPLA MAP.
  • Digital collections that meet the following criteria
    • Collections that meet DPLA's Collection Development Guidelines.

Nor do we encourage the inclusion of serialized content such as newspapers, or of archival finding aids described at the box or folder level).
    • Ability to provide metadata through OAI-PMH (many repository platforms, including DSpace, CONTENTdm, and Islandora meet this requirement.)
    • Availability of items on a publicly-accessible site (i.e., no paywalls, IP restrictions, or required log-ins)
    • Ability to store and provide preview or thumbnail images of the objects in the collection (this is a common feature in most systems)
