Greetings,

I haven't been aware of the following formulation of Ian's problem+solution in the thread so far. Apologies if I've missed it, or if (as I guess) it's deducible from someone's longer post.

vvvv httpRange-14 requires that a URI with a 200 response MUST be an IR; a URI with a 303 MAY be a NIR.

Ian is (effectively) suggesting that a URI with a 200 response MAY be an IR, in the sense that it is defeasibly taken to be an IR, unless this is contradicted by a self-referring statement within the RDF obtained from the URI. ^^^^

Is that about right? That fits in with Harry's remarks about IRW, and the general suspicion of deriving important semantics from the details of the HTTP transaction. Here, the only semantics derivable from the transaction is defeasible. In the absence of RDF, this is equivalent to the httpRange-14 finding, so might require only adjustment, rather than replacement, of httpRange-14.

Very nice. That seems like an accurate and very helpful way of looking at Ian's proposal.

The other way of looking at it, is that the once clear message of:

Don't use /slash URIs for things, use fragments, and if you flat out refuse to do this then at least use the 303 to keep distinct names

has been totally lost.

The advice is not that /slash URIs are okay and use them if you like, it's that they're not ok and you should be using #fragments. Don't dress the TAG finding up in other words to make it seem more favourable than it actually is.

I think this needs to be made clear for all those who don't realise.

missed a bit.. "200-means-web-page", not: 200 might mean, you can think it may mean, may be an IR.
