Publishing objects from Nuxeo to Calisphere is handled through a metadata harvesting process. Your Collection Administrator can initiate harvests for collections in Nuxeo that are ready for publication. Below is a summary of steps and considerations.

Metadata Requirements

In order to be harvested, the following metadata must be present in each record. Note that default values for Type, Copyright Status and/or Copyright Statement can optionally be supplied and applied to individual metadata records at the time they are harvested, using the Collection Registry:

  • Main Content File
  • Title
  • Type
  • Copyright Status and/or Copyright Statement

Defining Collections to Harvest from Nuxeo

Harvesting from Nuxeo into Calisphere works on a collection-by-collection basis. By "collection," we mean a group digital objects which are hosted in the same Project Folder in Nuxeo, and which you’d like to appear together as a set within the Calisphere interface.

We'll work with you to confirm which collection(s) you'd like to publish in Calisphere, and establish entries for them in our Collection Registry. This includes basic information about the collection that will be used on Calisphere (such as title and description).

Objects associated with a given collection must be organized within a Project Folder. (The Project Folder can, in turn, have nested Project Folders; in this scenario, all of the objects within the nested Project Folders will also be harvested).

Conducting a Harvest from Nuxeo to Test Calisphere Environment, QA, and Publication

Each time we run a harvest of your collections, we'll first put the records in a test Calisphere environment where you can preview and perform quality assurance (QA) on them.

If everything looks OK in the testing environment, we'll ask for your approval to publish the records in Calisphere.

That's it! Your collections will immediately be available on Calisphere, and they'll appear on the Digital Public Library of America (DPLA) soon thereafter (DPLA harvests from Calisphere on a bimonthly schedule).
