Hi Girish,

This is quite a big topic.  There is quite a lot of research on ontology versioning and evolution and a fair number of tools that support tasks related to these topics.  Here are some things related to Protege 4....

Some recent work, that is very nice, is work by Rafael Gonçalves at the university of Manchester - he looks at analysing changes between different versions of ontologies.  Here's a pointer to various publications on this:

Timothy Redmond and Natasha Noy have also done some recent work in this area and have produced a Protege 4 plugin.  Here's their paper

and here's their plugin

There's also the OWLDiff plugin:

In terms of versioning with SVN, there were some recent posts on the Protege mailing lists about this.  A search through the archives should reveal some interesting posts.

I realize that if I add a class or a property, I do not have to do anything. But otherwise, I will have to do something programmatically. Is there a users manual which explains maintenance of ontologies in general? Also, how does svn fit into these schemes? I prefer to use Eclipse/Windows development platform. Thanks much.
