Validation
This POC would focus on the mechanics of using an extension for the purpose of validation
- Pick a dead simple validation rule (e.g. required cardinality of a property)
- Pick a simple representation (serialization?) for the rule
- Specify responses that result from failed validation (4xx error?)
- Create an extension that filters all requests to Fedora, applying the simple validation rule
- New objects
- Modifications to objects
- Deletion?
- Verify that the extension produces the desired response
