at twine.com. It's a link to a pdf about OKKAM, the equivalent of a topic map that lets you look up URIs of things. It makes the same points I have been making about the use of URIs as identifiers (aka "names") for things: there is no central way at present to either control the distribution of URIs (anybody can make them up as needed, thus the potential to have the same entity end up with multiple "names"). OKKAM aims to solve that issue.
