Re: Content negotiation: Why always redirect from non-information resource to information resource?

Dear all,

  thanks for your helpful replies.  I will summarize with a few comments.

Of course the conceptual difference between a non-information resource and an
information resource is clear to me; I was rather concerned about how relevant
this is in an implementation where this difference is not needed.  (OK, I see,
one might initially be tempted to think "we don't need this" but then later
realize that "we should have sticked to good practices", so better introduce
it from the beginning…)

Given the FOAF example by Ross, I then wondered:  If id/me 303-redirects to
id/me.rdf, then id/me.rdf contains triples like <id/me> foaf:name "Ian
Davis".  Now if Ian Davis (not any external user) wanted to attach metadata to
id/me.rdf, e.g. <id/me.rdf> todo:needs "rework" where would _he_ do it?  Is it
advisable to put them into the id/me.rdf file as well, or should he rather put
them somewhere else?  In any case, the Halpin/Presutti paper mentioned by
Pierre-Antoine, of which I am somewhat aware, seems to give a reasonable
answer.

@Pierre-Antoine, your 200 OK / Content-Location solution appeals to me, as it
is actually what I initially asked for.  But given its non-support by browsers
it makes sense to me that it should not be used. 

I may eventually get back to you with more specific (and more philosophical!)
questions, as the domain I am actually mostly dealing with is the management
of mathematical knowledge.  E.g. me taking Fermat's last theorem (having
dc:creator "Fermat") and formalizing it in an appropriate language (e.g.
OMDoc), linking it to a proof and to examples formalized by me (or others) in
the same formal language, finally all having dc:creator <...#me>.  There, the
formalizations (= information resources) tend to be more important than the
non-information resources they originate from.  One would rather not describe
the non-information resource in the same language, but put a link to e.g.
DBpedia.

Cheers, and thanks again,

Christoph
