If we are to use http: based URIs for things which are never meant to be
retrieved (like ontology concepts), then it has to be before the retrieval
process, no?

Yes, we could invent some naming conventions and layer them over the top of
http, at least where http is capable of supporting the requirements; for the
last one, it's isn't.

Well, again, little of LSID is wholly new. In fact, the LSID protocol uses
other, standard protocols.

But inventing a new protocol is precisely what happened when HTTP was
created. Why did we not just reuse ftp? 

I think we are going around in circles here, so I'll leave the conversation
there.
