Steffen,

Great!

Effects of your tweak:

1. 
http://uriburner.com/describe/?url=http%3A%2F%2Fpurl.org%2Fmuto%2Fcore%23meaningOf&urilookup=1 
-- picked a property from your ontology as a random starting point

2. 
http://uriburner.com/describe/?url=http%3A%2F%2Fpurl.org%2Fmuto%2Fcore%23 -- 
pivot to the main ontology where the system leverages inverse relations 
courtesy of isDefinedBy .

As already highlighted by Richard, adding owl:equivalentClass and 
owl:equivalentProperty relations will lead to more enrichment esp. 
manifestation of instance data. All you have to do is add the relations 
and Linked Data power will handle the rest :-)
