[Biojava-dev] Re: Flyweight Ontologies?

[Matthew Pocock]

Oh dear. I can see this being a world of pain. I think ontologies and 
terms and triples should be flyweighted in the same spirit that 
alphabets and symbols are. However, I was going to defer the book 
keeping code untill the reasoner was working so that we could write it 
mainly in the ontology language. Grrr. Perhaps we need stable IDs?
