Re: Blank nodes as subject maps in R2RML

>From the latest R2RML draft:

* a subject map is a term map,
http://www.w3.org/2001/sw/rdb2rdf/r2rml/#dfn-term-map

* the termType property can be used on term maps,
http://www.w3.org/2001/sw/rdb2rdf/r2rml/#termtype

So "yes", you can use termType on subject maps and this is how you would
produce subjects as blank nodes.
