The definition of an IR, that it can be totally represented in a message is at odds with WebArch. A resources has a set of representations, there isn't any single representation given special status as "The One". It may exist, and this may be stated somewhere/somehow. (There is also the possibility of media types we haven't yet invented, cf. the hi-fidolity "thing/dog"). >From this I'd suggest it follows that we can't assume that a 200 means we're getting the canonical message. It could perhaps be argued that it's all very conceptual, that the set of representations considered as a whole contains the message. But I don't think this gets us any further in practice. Talking about description-oriented is an improvement in the sense that it gets rid of the need for "The One". But I reckon on the way it loses the notion of a representation. It seems easier to approach it from the other direction and say that a description is an approximation to content. Take a photograph of a traffic cop, It isn't a traffic cop, it's a graphic description of one. But you set that photo at the side of the road and cars will slow down. The description isn't the thing, but both can have the same effect. So I'd suggest a 200 would be legitimate for a description (in addition to what we normally refer to as content), because descriptions can be treated as representations.
