Description:
I noticed the query on the http://ontoworld.org/wiki/Property:Has_category page doesn't return anything, yet there are many instances of this property. I suspect the magic word "category" in the property name "has category" causes problems, as a query for [[Has instance::+]] works fine; or maybe there's a problem retrieving objects of properties in the namespace "Category:".
I tried to reproduce this on my own install, and the query worked with one test relation [[Has category::Germany]] in the wiki but failed with the test relation [[Has test::Category:Germany]] in the wiki.
Feel free to reassign this back to me for more research.
