A few quick comments...

I think taxonomies for classifying libraries for human location are (or
should be) more ephemeral than the universal identifiers of the
libraries themselves.

I wrote some remarks on this a few years ago:

Domain names are great for dividing up the universal namespace nowadays.
Languages like Java and XML use domain names for this purpose, and it's
not a bad choice for Scheme, either.

If "http"-scheme URLs were used for identifying libraries, I'd think
that each URL would actually be a reference to a Web object that could
by retrieved via HTTP to define the referenced library.  If we only
wanted a name for a library, I'd suggest not using URLs.  Is that what
you had in mind?
