Hi, if I was to knitpick, I would argue that the @id attribute in HTML identifies a fragment of the HTML document, hence not precisely a video ; for example, the video element has exactly one parent element (e.g. an enclosing div or section), which is not true of the video itself (that could be

Here are my 2¢ about the opacity of resources. First, let me point out that, contrary to what is often believed/claimed (and I plead guilty of having done so), URI opacity is *not* a constraint of the REST architectural style, at least as defined by Fielding in his thesis [1]. Then, AFAIK, the

Hi all, This is a cool stuff, indeed. I think an interesting use case would be to dig into a link to use its href URI instead of its text. Because let's face it, the web contains much more links with human-readable labels than plain URIs in the body of a page... I'm affraid my poor knowledge of

Hi Hugh, interesting suggestion; I have also been frustrated with dbpedia URIs in the adress bar, which you have to (or forget to) change when you want to feed them to an RDF agent... However, 406 seems to be the most appropriate answer to give. Falling back to 301 in too many different

Hi Simon, basically, I agree with you: having a single namespace makes the ontology easier to use, even if the terms are described in separate modules. More generally, there is not reason why the physical splitting into modules should necessarily result in a logical splitting into different
