Choose Visibility

In order to be able to change the visibility of the classes and properties in the web interface, KIM uses a visibility mechanism. The new resources have to be defined as visible in
KIM/context/default/kb/visibility.nt . Here is an excerpt:

<http//example.org/ontology/Actor> <http://www.ontotext.com/kim/2006/05/kimso#visibilityLevel1> "" .
<http//example.org/ontology/Artist> <http://www.ontotext.com/kim/2006/05/kimso#visibilityLevel1> "" .
........

Clear the cache of KIM (remove KIM/context/default/populated) and start it again, you should be able to see the additional classes in the ontology view.
