We are in the process of setting up a workable harvesting mechanism for the technical staff at the Digital Public Library of America to use to harvest metadata from the Mountain West Digital Library for selected collections. Working with DPLA Assistant Content Director Amy Rudersdorf, I have mapped the metadata fields from our Primo normalized XML files to the DPLA Metadata Application Profile, version 3 (MAP V3). I was pleased that we were able to offer most of the suggested fields. You can see the current version of the mapping of MWDL metadata to the DPLA Profile if you like — understand that it is highly likely to keep changing! The DPLA Profile itself may well change in response to the intensive testing that is going on as part of the Digital Hubs Pilot Project.
