Hmm.  I'm not sure if I'm adding value, but I'll try once more.    (01)

Well, yes, if you download the whole ontology and then ask for a particular 
term.  I'd kinda like to just ask for a particular term and only have that term 
downloaded.    (03)

Umm, you know, like, 'tracking'.  Like revision tracking.  Like change control 
tracking.  Like, keeping track.  I seem to lack the right 
(non-self-referential) words.  How about: Telling me what I had before and what 
I have now and what the difference is.    (05)

And I'm sure Protege and others can difference two ontologies that I've 
downloaded off the web.  What they can't do is tell what what the state of 
ontology X was last week, or last month.  A controlled repository can do that.  
And if it's a particularly nice one, it can do it at the whole ontology level, 
or at the single term level.  This is a service that is not provideable via a 
straight web service.    (06)

Sure, if the only service you want is URL access. Multiple types of interfaces, 
like give me this ontology in some other format, or give me the terms that 
match certain patterns.    (08)

Ah, well, I'd say no, because it introduces a level of indirection, and it 
means downloading big ontologies and then processing them from beginning to 
end, instead of (potentially) indexing to a particular term on the local 
machine.    (010)

But sure, it would work for most features, and it's an interesting model that 
has a number of advantages.    (011)

At this point I think we have to toss the thread over to the requirements 
thread, which is a better home for the types of things I've been describing 
anyway.  I suspect that both implementation approaches can be used for many of 
the requirements.    (012)
