I agree with this.
This problem is caused that Linked Data conflates identifiers with
locators - important is that one can get information about a unique
name, by using it as a locator. The issue whether some events in the
process or outcome of the information retrieval somehow should affect
users perception of the name (is it a document or xyz?) is a can of
worms most implementers don't want to tackle and they have a point. I
don't want to maintain all apps I once coded so they support whatever is
the latest HTTP semantics trend is, when there is a widely used standard
for extensible, *evolvable* information representation (RDF) which I am
already expecting to receive about the name I am retrieving info about.
So lets not presume that by dereferencing an URI and getting back a
document, the URI is the documents identifier - it is its locator. It
can be its identifier too, but lets leave that for publishers to decide
- that has been the point of my previous post on the topic (
