Blank Nodes as properties in JSON-LD

Hi,

I just thought I'd send in a comment regarding blank nodes as properties.

My thoughts are that they should stay in. The constructions of 
properties would be somewhat simplified if I did not have to specify an 
"@id" and skolem IRI at runtime.

My particular use case is a simple DL and reasoner with role 
intersection and role union constructors. These minted roles would 
appear as properties in the resulting JSON-LD ontology.
