PPC Metadata Guidelines for DPLA Participation
The PPC metadata guidelines include Plains to Peaks Collective (PPC) and Digital Public Library of America (DPLA) requirements, recommendations and best practices for preparing your collection’s metadata for participation in the PPC and the DPLA. These guidelines are not meant to be a comprehensive cataloging guide but rather a guide for sharing data with the PPC. The PPC does not recommend a particular metadata schema, as every institution’s needs are different. However, we do offer crosswalks to MARC, MODS, and Qualified Dublin Core.
PPC Ingest Process
The PPC ingests data from our partners via OAI-PMH, xml files, json files, API and occasionally spreadsheets (though this is most cumbersome for partners). If you are unsure how your system shares don’t hesitate to reach out.
Once you share your data it is then normalized and aggregated into a single output, which in turn is shared with the PPC platform and harvested by the DPLA. All metadata contributed to the PPC and the DPLA will carry a Creative Commons Zero (CC0) Public Domain Dedication (http://creativecommons.org/publicdomain/zero/1.0/). However, the item being described can carry different rights.
The PPC will share digital collection items with the the PPC platform and the DPLA four times a year; late October, January, April and July.
Technology
The PPC uses an aggregation tool to bring together the varied and customized metadata formats of participating cultural heritage institutions throughout the states of Colorado and Wyoming. Once harvested, the metadata is transformed and undergoes analysis before being published to our Veridian-created search platform.
