What's happening in the Topic Maps world?
Demonstration Topic Maps aren't always about Opera. BeerTM "is a collaborative project to create a topic map about beer. The idea is to first create an ontology for describing beer, and then allow people to provide their own content using that ontology. The topic maps provided by different people can then be merged together to yield larger data sets." Geir Ove Grønmo has chipped in with his own impressive contribution.
TM4J 0.8.0 adds a new persistent storage model for relational databases. This storage model uses the Hibernate O-R mapping tool and supports a wide range of databases. This back-end has been tested against MySQL, Oracle9i and Oracle 8.
Mary Nishikawa has invited participation in a new Topic Map Constraint Language mailing list. "Graham Moore and I are now preparing to update the requirements document for the Topic Map Constraint Language (TMCL)... Please join http://groups.yahoo.com/group/tmcl-wg/ if you would like to participate or just follow the discussions."
The GooseWorks site has been revised and includes TmTk 0.7 (topic maps toolkit) for download and a demonstration of mod_topicmaps 0.4.
