Contribute to Calisphere

Calisphere is based on a metadata harvesting model, where we can pull in metadata and thumbnails that point to content hosted on your own site or system. Our goal is to make it easy for institutions of all sizes and with varying technical infrastructure to contribute to Calisphere.

Baseline requirements for harvest

A collection must at minimum meet the following requirements in order for us to consider harvesting it:

  • It must be digital (i.e., not metadata-only records)
  • It must be publicly available
  • It must be hosted on a stable system or site

It's a twofer!

All metadata that is aggregated and displayed on Calisphere is also pushed to the Digital Public Library of America (DPLA) website and platform.

Calisphere's harvest works on a collection-by-collection basis. By "collection," we mean a group of digital objects which are hosted in the same source, which can be harvested according to the same protocol, and which you'd like to appear together as a set within the Calisphere interface. Some institutions have a single collection, and some have many. We'll work with you to confirm which collection(s) you'd like to publish in Calisphere and add them to a harvesting queue.

The first step to contribute to Calisphere is to simply let us know you're interested in having your collection(s) harvested. If you have a collection or collections that you'd like to have harvested, and that meet the baseline requirements above, please contact us.
