Hi all,

We're using TopBraid Composer Standard to edit an ontology with lots of OWL classes. We'd like to keep track of when classes change (e.g. labels are added or modified, or properties changed).

Is there an easy way to have the editor keep track of metadata such as created and modified timestamps? I'd imagine something like SPIN rules or triggers could be useful for this.

I found this blog posting about change metadata:
http://topquadrantblog.blogspot.fi/2009/09/creating-and-managing-metadata-about.html

It mentions that "TopBraid Composer inserts change statements automatically". But I have not seen such statements in our data. Is this something that has to be enabled somewhere?

Thanks for any help,
Osma
