In addition to automatic sharing of your Calisphere collections with DPLA, you have the option to further share collections in DPLA with Wikimedia Commons. This pipeline is being developed by DPLA, through a pilot program in 2020. The Wikimedia Commons is a large and growing aggregation of freely-available content. Files from Wikimedia Commons can be used across all Wikimedia projects -- including Wikipedia.
The Calisphere-DPLA-Wikimedia Commons Workflow and Requirements
Process-wise, this includes providing some additional information in the metadata for your objects so that they can be made available through Wikimedia Commons:
- A Rights Status using a RightsStatements.org or Creative Commons URI, indicating an open rights/licensing status for the item allowing for any type of re-use, including commercial.
- URL references to source media files, for copying through to Wikimedia Commons. Alternatively, provide a URL reference to a IIIF manifest.
Once the objects are in Calisphere, DPLA will harvest them from Calisphere. DPLA harvests from Calisphere every two months, which is the most frequent harvesting schedule. They re-harvest every January, March, May, July, September, and November -- typically in the middle of those months. This means that the longest your data will be "out of sync" between Calisphere and DPLA (if you make a change) will be two months. Once the objects are in DPLA, they will make them available to Wikimedia Commons on an ongoing basis, on a schedule to be determined.
