Re: [Zope-dev] RFC: RelationAware class for relations between obj ects

So the answer of what acts as a reference id for the referred-to object is: "Whatever the best id that your framework provides you is."

If your framework is Zope3, a hubid is what you should use. In Zope2, a path or tuple containing (storagename, oid). In ZODB-sans-Zope, an oid (or a (storagename, oid) tuple with the storagename an empty string).

I wonder if a single framework could adapt to fit the needs of all 3? It seems doable (different plugins to store the IDs, 'traverse' to the objects), I think...

Yes, it would be elegant and I don't think it would be complicated at all. For Zope 2, I think you'd either use a path or a hub ID (assuming the object hub gets backported. ;-) ) Shane
