ISSUE-27: NULL graphColumn value producing triples in an unnamed graph

unnamed graph?

NULL graphColumn value producing triples in an unnamed graph

State:

CLOSED

Product:

R2RML

Raised by:

Description:

From section 3.3.1 of the editor's draft of the R2RML spec (http://www.w3.org/2001/sw/rdb2rdf/r2rml/#SubjectMapClass_graphColumn_Property), regarding the rr:graphColumn property:

"If for a row, value from the specified column is NULL, then the triples generated from that row will be stored in an unnamed graph."

Is the "unnamed graph" mentioned here intended to be the "default graph"? If "yes", then I suggest clarifying the text to refer to the default graph. If "no", then it is not clear to me what this text means.
