Hyku’s Underlying Metadata

Hyku’s Underlying Metadata

Within Hyku’s stack lies Fedora, which creates a layer of technical metadata that might be useful for you.

One of the reasons to move to Hyrax/Hyku from legacy systems is the underlying RDF-based Fedora-4 layer, so it is important to understand what this means for your metadata and data as a whole. Work at Indiana University has created two great documents to help you understand Fedora’s metadata and a switch from XML to RDF:

So while objects in Hyku have most of their metadata at the generic work level, available to view here, theres still quite a few things that exist at the Fedora level, some of which is shown here.

Below are the fields shown in a sample generic object in Hyku within the Fedora GUI.
