Okay, as far as I get, this is then a On-the-Fly-Property[1], or? I 
catched up the modelling approach of the Property Reification 
Vocabulary[2] made by Toby Inkster and designed it as an Ontology[3]. 
One can create now implications for inferencing. The prv:shortcut 
property should be handled the case of restriction or verification of 
the applied shortcut property.

Although, where is now the difference to RDF-Reification? ;)

Cheers,


Bob
