Maybe I am still misunderstanding, but I think that you rare still saying
that a urn/doi approach is compatible with Linked Data, or at least is not
I think differently.
urn/doi is harmful - once it comes into existence, it is very hard to avoid
the problems of people using them, and then you have to start working out
where the server might be.
I am quite happy with people passing round http://foo.com/bar/urn:baz.quex,
as this is resolvable; I just don't want things that don't use http.

I think Bernhard's questions suggest that your comments might have been
misinterpreted by him as I did, that urn: is acceptable as a Linked Data
Were you saying that?

Sorry to be purist, but I can't seem to distinguish between Linked Data and
HTTP based Linked Data - it just isn't Linked Data if it isn't http.
