The issues list says that the issue of allowing blank nodes as
properties is "postponed till a future Version of RDF" [1].  The Test
Cases also show the N-Triples syntax [2] does not allow it.  The final
nail is probably "Arcs are labelled with URI references" in [3].  Of
course these are still working drafts, and the sun could rise in the
west tomorrow.  :-)

Can I ask how this issue has been affecting your development work?
