Re: [higgins-dev] Change to IDigitalSubject

[Greg Byrd <gbyrd@xxxxxxxx>]

It's just a suggestion.  I'll be happy to hear input from others.

If, however, IResource is meant to encapsulate a resource in the RDF 
sense, then it makes sense to me that IDigitalSubject is a specific type 
of resource.  In other words, a DS will always be a resource in the RDF 
sense.  So if we're exposing the notion of RDF resource through the API, 
then it's consistent to view IDigitalSubject that way.

Just to play Devil's advocate -- if we're exposing RDF notions in the 
API, why not use Jena or some other API instead of inventing our own.  
They already have Resource, Literal, etc.  (The practical answer might 
be that it takes too long to get permission from Eclipse to include 
third-party code...)
