Here is my analysis of some discussion in the Semantics Task Force today. The semantics group was discussing what changes need to be made to SPARQL 1.2 Query Language to handle quoted triples. It appears that the normative changes have all been made - the functions on quoted triples are all in and the grammar changes are also in and no changes to BGP mapping need to be done. It turns out that SPARQL BGP matching is insensitive to transparency of IRIs and literals because it matches simple entailment where there are no derivable equalities. Making blank nodes opaque, however, would require changes. There are some informative text that should be added to the document, though So what is needed to get to a state where the fundamental core of our set of documents include quoted triples is to decide on a semantics for quoted triples and update RDF Semantics accordingly. And this depends, in my opinion, on which use cases the working group wants to support. There may also be some more changes required to the surface syntax documents. peter
