There, <http://example.com/about#alice> is the name for alice, and that is described along with a lot of other objects in the IR <http://example.com/about>.  As the authors there discuss it, this is better for 'small' sets of names, whereas "the slash URI pattern" as described there is better for larger ones.

Indeed, I think I eluded to this in my email to the "303" thread. The idea is to have smaller more manageable RDF documents on the web, IMHO targeted documents are more interesting than ones which talk about a million and one things. Again, I will try and draw an analogy here; at is stands, sites like the BBC, have one document per story, there is nothing stopping the BBC from having one page will all of its content on it, i.e. with each article having its own #fragment, but it is a lot neater to have a document per story.

Mischa
