Questions and Things We Need For Final Decision Making

Directionality of Properties

At my previous institution, we had an external triple store that also kept nodes and triples about our resources in Fedora. This allowed us to do face SPARQL queries for interoperable applications and allowed us to use fewer properties. For instance, properties were always placed on the child resource to point at a parent and not vice versa. Currently, the pattern here seems to be to use both properties. In many of my examples, there is little consistency about this as I still need to understand more about the Fedora APIs to make a recommendation. If I remember correctly, many of the ideas in the Fedora 3.8 API were dropped in Fedora 4 (e.g. getRelationships). Because of this, we need to think more about directionality and the API before we determine the relationship between properties and instance of classes.

Existing Fedora Content

We have a lot of content already modelled in Fedora. My instinct is to keep that stuff modelled as is and instead build logic to look for new models whether than readjusting. Can we do that?

Omitting Valid Properties and Classes

PCDM is designed not to express a specific method that must be followed to create a certain concept. Instead, PCDM allows for flexibility and room for institutions to approach problems differently for their own use cases.

In this document, certain valid properties and classes have been intentionally omitted to keep things as simple as possible. While doing this is valid, it may cause problems for other institutions that try to adopt any software we write or try to write with the community. As a result, we need to decide whether we should add more complex components or simply try to account for other approaches in third party tooling we write.

Should Canvases be an Instance of pcdmuse:IntermediateFile or pcdmuse:ServiceFile

Depending on what we ultimately decide to store and serve, we need to choose one of the two options and reflect the decision across all attached documentation.
