Regarding ACTION: DanC find decision record for bnodes in predicate I'm not able to confirm from records that the WG decided to take bnodes out of the predicate slot. As of 11 Oct, we were resolved... "that the grammar in 1.501 addresses issue punctuationSyntax" -- http://lists.w3.org/Archives/Public/public-rdf-dawg/2005OctDec/att-0055/11-dawg-minutes.html#item04 And as of 1.501 the Verb production was VarOrBlankNodeOrIRIref. As far as I can tell, the issue has remained closed since then. http://www.w3.org/2001/sw/DataAccess/issues#punctuationSyntax The change to take BlankNode out of Verb was in... Revision 1.629 2006/01/30 17:38:14 aseaborne - Removed bnodes from triple pattern predciate position Definition and syntax I don't see a relevant decision between 11 Oct and 30 Jan. I could be missing it, but I'm looking pretty hard. The WG approved the CR candidate (1.664 2006/03/21), but as we're discussing, it's inconsistent about whether bnodes are allowed in Verb or not. Perhaps the WG approved a relevant test case? I'm not sure how to search those easily.
