- Higgins.owl: we need to add the full set of DatatypeAttribute subclasses that correspond to the XML Schema types. We currently have only StringDatatypeAttribute, Base64BinaryDatatypeAttribute, NormalizedStringDatatypeAttribute but need to add all the rest.
- At present, other than having an Attribute subclass for each of the std OWL (XML Schema-based) literal datatypes, we have defined no ObjectAttribute subclasses. The question is should we go a bit further and define some very common complex types such as postalAddress? or even tricky singled-stringed values such as zipcode?
- The 'source' metadata property is currently a SubjectRelationship (that points to a Digital Subject that is usually in some other Context). But there are times when we know more; when we know the source Attribute held by the "source" Digital Subject. Maybe we need 'sourceSubject' and 'sourceSubjectAttriubte'?
- We've not resolved how to declare user-defined Classes to be 'closed', that is instances of them should follow the class definition, but not include any other "extra" properties.
