Here is a summary of the changes, sorry for not providing that before.

- used owl:Class and owl:DatatypeProperty instead of rdfs:Class and 
rdfs:property. That shouldn't change anything.

- introduced owl:ObjectProperty (which lead to your question).

- changed its:domains to have a string data type. Before the data type 
was anyURI. That would not allow a list of domains.

- changed its:localeFilterList to be a string data type, for the same 
reasons.

Best,

Felix
