Lars, Graham,

N0396 says in 3.1:

"A locator is a string that references one or more information resources"

The note at the end of 3.4.5 says:

"Locators which refer directly to subjects which are not information
resources must be used with caution. They should not be used in the
[subject addresses] property, as this is intended only for references
to information resources. Rather, they should be placed in the
[subject identifiers] property."

The two statements contradict each other.

I strongly advice us NOT to try any 'fixups' towards interoperability
with RDF. I think that topic maps are far better of if they stick to
the idea that "a URI allways refers to the information resource that (might)
be returned by an HTTP GET. There are no locators that refer to abstract
concepts." Anything else is introducing evil, IMHO.
