I think it's probably a good thing to use existing vocabs in your overall 
scheme, where they exist and are defined to serve the purpose in the way 
you want.  Modularization of vocabularies seems like a good thing to me.

As you say:

As for assigning URIs, I do that sometimes.  It can be useful to assign 
URIs when you want to mention the same person several times.  Otherwise a 
blank node can do.  In practice, I find they work pretty much the same.  In 
fact, it's one of the areas I find that RDF data is very much more 
convenient than more prescriptive data formats.

 From my experience, I'd say that using Jena ModelDB as a back end is a 
good plan.  I believe it would take very little work to link my stuff to 
Jena in this way (I just haven't got round to doing it).

Something else I haven't properly exploited in my own issue tracking work 
is use of inference rules. E.g. using Cwm to calculate things that can be 
deduced, rather than entering the same information in different ways, which 
is what I do at the moment.  Again, it would be dead easy to do (at least 
for for some of the duplicated information I've noticed), but I just 
haven't got round to doing that yet.
