I have already read the document entitled “Defining N-ary Relations on 
the Semantic Web” which is available on the following link 

I want to define supervisor as a property having domain and range 
person. This property carries data defining where and when this 
relationship (supervisor) was established. In order to infer the inverse 
property, i associate the /OWL:inverseOf/ apprentice to supervisor. I 
want to define the supervisor property as a sub property of a more 
generic relationship called /knows/ as defined in the FOAF schema.

I use the reification method to represent all this information as follow:

The problem that the management of the blank node is very complicated.

My question is there a solution to represent a property as a class in 
such a way that the class keeps the characteristics of the property 
(i.e., transitivity, inverse, symmetry etc) without representing the 
blank node?

Waiting your response,

Beast regards,
