Its a pleasure to announce the first release of Metatribble, an attempt to implement some of the concepts of semantic annotation that I talked about in a previous post. Metatribble is currently packaged as a Ubiquity command and right now doesn't do an awful lot except for mark up interesting entities with RDFa, but even just that is kinda cool :-)
If any of you are using NPCL to write your topic map ontologies, you should know that we have just released a new version of the NPCL Schema Editor. Includes MSBuild support, compiling multiple NPCL files into a single file, auto-generated documentation and much much more. Fun for all the family and competitively priced at $0. For more info see the release announcement on the NetworkedPlanet blog.
