How should a use term config file look?
Validation: duplicate uses in a FileSet, Files with no use

Minutes

Takeaways:

How to configure pcdm:use options?
- We can use quesitoning_authority gem.
Should we validate cardinality for pcdm:use
- Validating "required" would be much easier than validating cardinality. So let's start with that.
How opinionated should code be about what goes into a FileSet?
- Not too much.
- Ideally, we should encourage implementers to consider a FileSet as a logical unit containing files that are derived from one another.
- A typical scenario would be a FileSet containing one "orginal file", with multiple other files derived from it.
- We want to steer people away from combining Files into FileSets where the Files are not derivatives of each other.
- Instead, we would encourage creating separate works, and then grouping those works together through a common association to another "parent" work.
- This assumes a feature of being able to "nest" works, which doesn't fully exist yet.
- However, there are use cases that introduce some gray area here.
- For instance, media files that have transcripts, i.e. are the transcripts actually derivatives?
- In these in-between cases, we prefer to not be too prescriptive, and allow implementers to choose the model that best suits their needs.
Consider putting diagrams for data modeling use cases on the PCDM wiki.
PCDM Use Validator in Hydra-Works.
- This is just a sketch (in Ruby) I drew up after the meeting, of what one might look like.
- Similar to Hydra PCDM Validators like these: http://www.rubydoc.info/gems/hydra-pcdm/0.9.0/Hydra/PCDM/Validators

Previous Action Items

Esmé Cowles: add a comment to https://github.com/projecthydra-labs/hydra_file_sets_wg/issues/5 outlining some of the examples we have discussed for richer metadata attached to a FileSet.
scossu: draft a use case for multiple Files with the same use value, or no use value, attached to a FileSet. (see Re: 2017-01-05—FileSets WG Meeting)

Action Items

Drew - demonstrate progress on metadata-as-files branch of Hyrax
Stefano - demonstrate using QA to provide options for pcdm:use
