Chimezie

   We have a new member, Chimezie Ogbuji.

   Chime's intro:
   [30]http://lists.w3.org/Archives/Public/public-rdf-dawg/2007AprJun/002
   1.html

   <AndyS> Hi there!

Leading digits in prefixed names

   <LeeF> [31]Alan Ruttenberg's message

   <iv_an_ru> No problem for me and no preferences, so decide as it

   LeeF: The situation is different from how it appears in the agenda.
   Alan's message in the comments list asks whether digits might be
   allowed immediately to the right of the : in SPARQL qnames.

   <jeen> example: foo:1bar

   LeeF: Concerned about schedule and hesitant and anything that risks
   it. However, have been advised that might be able to pass it without
   requiring a new Last Call.

   <chimezie> Support for syntax beyond QNames towards CURIEs (perhaps)
   seems like a good idea to me (niavely WRT schedule)

   <iv_an_ru> Alan uses Virtuoso so I'm biased and I'll vote for a
   decision that is most convenient for Alan :)

   LeeF: Would like to gauge the technical merit with the WG.

   SimonR:I'd provisionally oppose it because it can't be serialized into
   RDF/XML.

   <chimezie> Doesn't have to depend on CURIEs per se

   <AndyS> Only issue I can see is around "ex:2" which is (now) two
   tokens and becomes one but I think that still only turns illegal
   syntax into legal. I can't find a legal to illegal query
   transformation.

   Chime: URLs that have escape characters that aren't allowed at the end
   of a qname. E.g. %

   <chimezie> % characters

   <chimezie> <urn:foo:bar/Base%20Uri>

   <ericP> <[32]http://example.org/foo.html#xpointer(blahblahblah)>

   <chimezie> assuming base of <urn:foo:bar/Base> what is the QName

   <ericP> i.e. all of xpointer has this problem

   <LeeF> AndyS: We call them "prefixed name" because they are not the
   same as XML QNames

   AndyS: Prefer not to mention XML QNames; we should rather talk of
   "prefixed names" which are not the same thing.

   SimonR: If we have a CONSTRUCT template with one of these, then it
   can't be serialized into RDF/XML

   AndyS: We're already in that situation though

   <chimezie> The workaround (for the query author) of course, is to use
   the expanded form

   <LeeF> Or to use BASE sometimes? :)

   <iv_an_ru> Expanded forms result in too much typos :|

   LeeF: Seems to be enough support to go ahead; will consult Ivan and
   see about getting it on next week's agenda.

   AndyS: EricP, do you have any ideas about the politics around CURIEs?
   EricP: Nope!

   AndyS: Not in favor of mentioning CURIEs; just modify our own
   definitions to be more accommodating.

test suite

   Jeen: The tests we marked approved have been officially marked. Also,
   sent an email:
   [33]http://lists.w3.org/Archives/Public/public-rdf-dawg/2007AprJun/002
   8.html
   ... went through the tests to see what the status was, marked them all
   as either out of date, already moved, or to be moved/examined.
   ... Most interesting ones are the tests regarding sorting, and i18n.
   ... All need to be eyeballed and have judgements made about whether to
   discard, rewrite, etc.

   AndyS: How much coverage do we have over the spec?

   Jeen: In the new suite, nowhere near full coverage yet. Still many of
   the old tests are close to up-to-date; once those are moved, good
   coverage of the inportant features of the language. Most doubtful area
   is RDF semantics, as a result of major editorial changes.

   LeeF: Eric, what is yacker's potential...?

   EricP: Hoping to be able to run yacker, then XQuery to automate much
   of this.

   <ericP> <tests><test name='...'>... xml tree for test </test><test ...

   <LeeF> [34]4 regex tests

   LeeF: We have the 4 regex tests above validated by several sources.
   Any else had a look at these?

   (silence)

   <iv_an_ru> They were running by my automated test suite so they're OK
   for me. But I did not even look at them by eyes.

   <LeeF> PROPOSE to approve the 4 tests in
   [35]http://lists.w3.org/Archives/Public/public-rdf-dawg/2007AprJun/001
   8.html

   <LeeF> ericP: second

   <LeeF> resolved.

   approved with no objections or abstentions.

   <LeeF> ACTION: LeeF to mark the 4 regex tests approved [recorded in
   [36]http://www.w3.org/2007/04/24-dawg-minutes.html#action11]

langMatches

   [37]http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2007A
   pr/0023.html

   LeeF: EricP, would you like to speak about the langMatches issue?

   EricP: Jeremy Carroll points out that originally langMatches was
   presumed to be defined by [38]RFC 3066, now supplanted by [39]RFC
   4647. We forgot to specify which one in the spec. Basic and extended
   language codes make a difference. Do we want to identify basic, but
   also have tests prohibiting extended langMatches?

   AndyS: The differences are quite obscure, related to the script a
   language is in.

   LeeF: Seems like a good thing to test, but we're not obligated to do
   so.

   EricP: Favors testing it.

   LeeF: Invites Eric to write up a test for it. EricP: Okay.

   <LeeF> ACTION: ericP to write a test showing that langMatches doens't
   do extended matching [recorded in
   [40]http://www.w3.org/2007/04/24-dawg-minutes.html#action12]

application/sparql-query

   <EliasT>
   [41]http://lists.w3.org/Archives/Public/public-ws-desc-comments/2007Ap
   r/0001.html

   EliasT: WSDL WG suggested that we propose our own non-XML extension.
   They wanted to know whether we wanted to raise an issue about it; we
   didn't want to hold them up.

   LeeF: Guess we'll probably not pursue this for lack of motivation.

   <scribe> ACTION: EliasT or LeeF to reply to Bjoern w.r.t.
   application/sparql-query [recorded in
   [42]http://www.w3.org/2007/04/24-dawg-minutes.html#action13]

www 2007

   SimonR: I'm definitely not going to be there.

   <iv_an_ru> I'm at www2007 iff I get visa.

   <jeen> not me unfortunately

   <Souri> *not* me

   EliasT won't be.

   <iv_an_ru> Orri Erling is there for sure.

   LeeF, EricP and Orri Erling for certain, Ivan a possibility.

   LeeF: Prefer not to miss a week this close to the finish line, so will
   have a telecon as usual.

LC comments

   <LeeF> [43]last call comment tracking

   LeeF: Shows which threads are closed, waiting, contact points, etc.

   <jeen> nice and short, that overview

   LeeF: Coordination group notes that given the history of this group,
   ought to review comments from previous LC and see whether they should
   be reopened. Awaiting sufficient insomnia to tackle that....

   AndyS: Re P�rez et al's work on SPARQL semantics, thinks it was cited
   in the informative sections of the document.

   <LeeF> ACTION: LeeF to mark the FROM * / FROM NAMED * thread as
   [CLOSED] [recorded in
   [44]http://www.w3.org/2007/04/24-dawg-minutes.html#action14]

   Chime: Satisfied with the response to his LC comment -- LeeF to
   officially reply and close it.

   LeeF: Going forward, resolve the qname thing, seem to have responded
   to all the LC comments. We have a good shot about being ready to
   propose the move to CR next week or two.
   ... Any further issues?

   EricP: [45]RIF Core went to WD1. Anyone want to look at this?

   [46]http://www.w3.org/TR/2007/WD-rif-core-20070330/

   Chime: Might be interested in looking at it if it was clear what the
   relevance was....

   Chime is curious enough to give it a look, but would like guidance on
   what to look for.

   SimonR: The relationship between RIF and DAWG is *probably* similar to
   SPARQL and extended entailment regimes like OWL, etc.
