Zope implementation of topic maps. Gnowledge Networking and Organizing System by nagarjuna on 2002/07/24 [Zope Products] seems to be an implementation of topic maps as a Zope product. Interestingly, it claims to have implemented facets, which an article by Steve Pepper, CEO of Ontopia suggests have been dropped in the XML version of topic maps because "... information resources could also be subjects (and hence topics). This rendered the concept of facets superfluous since metadata properties can now be assigned to a resource as characteristics of the topic that represents the resource." I read that paper the other night, and I need to go through it again because I couldn't work out have many of the different aspects were actually distinct. I'm sure it's because I was knackered, except in the case of facets - the note referenced above unfortunately comes at the end of the section so I only read it after being confused by them for a while.

Book reference bookmarklet. The Weblog Bookwatch has a bookmarklet for posting items about books. I don't have time to work out how to use it with Radio at the moment, but I'll check it out when I get time. It should work with ISBN numbers and Amazon book pages. This is just the sort of thing I'd like to do with the floodrisknet web site, but for journal papers. I figure it should be possible using CrossRef DOIs. I reckon that if people could have a bookmarklet to post publication info on the web site, then at least those who use online journals (getting to be most everyone as libraries cancel print subscriptions to cut costs) might find it easy enough that they will post anything they come across that would be of interest to others.
