I have no strong opinion on the general issue of "uid" vs. "uri"; was just raising what I think might be an important question. But I do disagree with the above. Ids like isbns and asins are used to refer to abstract concepts (books, and audiovisual works* respectively), so it's rather meaningless to assert that you can grab such a thing from any one location. Yes, a book might be available at Amazon, but it's also available in thousands of other locations. Likewise with dois, which might resolve to different locations depending on various factors. There are some library hackers (Dan Chudnov et al) doing some interesting work with proxies that take standardized uris of this sort and then, depending on the prefixes, grab the associated metadata from the approprirate service (pubmed, Amazon, Flickr, etc.). I believe that this question in part was connected to that sort of work, since Ed is involved in that.
