We do just fine minting our URIs at LC, Andy. But we do appreciate your
concern.
The analysis of our MODS URIs misses the point, I'm afraid. Let's forget
the set I cited (bad example) and assume that the schema is replicated at
several locations (geographically dispersed) all of which are planned to
house the specific version permanently. The suggestion to designate one as
cannonical is a good suggestion but it isn't always possible (for various
reasons, possibly political). So I maintain that in this scenario you have
several *location* none of which serves well as an identifier. I'm not
arguing (here) that info is better than http (for this scenario) just that
these are not good identifiers.
