Re: [OWLAPI-developer] Module Extractor

[Thomas S. <sch...@cs...>]

There is now an example showing how to use the module extraction  
feature:

      http://owlapi.sourceforge.net/documentation.html -> "Code  
examples" -> "Module extraction",

which links to

      http://owlapi.svn.sourceforge.net/viewvc/owlapi/v3/trunk/examples/src/main/java/org/coode/owlapi/examples/Example16.java?view=markup

Cheers

Thomas
