The process by which a URI comes to identify something other than the
stuff you get by resolving it can be mysterious- I've blogged about a
In the case of worldcat or google, it's fame. If you think a URI
can be usable outside your institution for identification purposes,
and your institution can maintain some sort of identification
machinery as long as the OpenURL is expected to be useful, then it's
fine to use it in rft_id. If you intend the uri to connote identity it
only in the context that you're building urls for, then use rft_dat
which is there for exactly that purpose.
