A point release but I haven’t mentioned DataCleaner since before version 2.4. Sorry.
True, DataCleaner doesn’t treat all information structures as subjects, etc., but then you don’t need a topic map for every data handling job.
Opps! I don’t think I was supposed to say that. 😉
Seriously, you need to evaluate every data technology and/or tool on the basis of your requirements.
Topic maps included.
