ok, so this is a wishlist, so I am allowed to just add my "in an ideal  
world"-personal-my-private-little-hat-on favorites :-)

I have the following:

- Turlte has been mentioned exhaustively already... I'd also like to  
have a "Terse RIF syntax": I think a more RDF based
   syntax for RIF is still missing for RIF being picked up by the RDF  
community. If that meant rubbber-stamping N3 and
   nailing down its corresponding RIF fragment, that could be a good  
starting point.

- Annotations for RDF: apart from quads/named graphs, you want to give  
arbitrary annotations to RDF triples
   (time, provenance, trust, etc.). Is reification (without any real  
reification semantics) which is the
   only existing way to support annotations, really the right way to  
solve this?
   I think that would be a good time to taking a step back and looking  
at triple-level annotations with
   fresh eyes once more?

  - closing the XML-RDF gaps: It seems that the XML and RDF languages  
specing goes determined parallel
    paths in W3C with no real visible perspective for convergence.  
Integrated XML+RDF query languages,
    or maybe an XG for XML2RDF/RDF2XML would be cool: GRDDL is a  
starting point, but the current way to
    translate into RDF/XML and then use XML transformation languages  
instead of directly using SPARQL/SPARQL-Update
    seems like an unnecessary detour.

In general, I think a workshop on "RDF what's next" or specific  
workshops to any of the above-mentioned topics would
be necessary/welcome. The easy to solve issues (what anybody a lot of  
people are using, things like Turtle, named graphs)
should probably go right into rec track, for the othe issues XGs might  
be a good instrument.

Nice, so now thatI've written that down I can wait for Chrismtmas and  
see what Santa Sandro will bring ;-)

best,
Axel
