convene
<scribe> Scribe: DanC
AFS: I sent a correction re # of actions...
KC: I think this is the corrected version
<DanC_> [15]minutes 18 Apr
[15] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006AprJun/att-0052/18-dawg-minutes.html
RESOLUTION: to approve minutes 18 Apr
future meeting times
KC: our scheduled time overlaps with RIF. it's not clear how much of
an actual problem that is, but it's at least a potential problem.
... how about an hour earlier?
<AndyS_> I'm happy to move -1 hour.
DC: how about 9:30am Boston time, year round? [or at least over this
summer]
<AndyS_> (14:30 BST(GMTDT) , 13:30 GMT)
hmm... 60, 90, or 120 minutes? weekly, every-other-week, or monthly?
<AndyS_> CET is +1 hour to that.
PatH: I lean toward frequent meetings and make them short if there's
not much to do
<SteveH> as long as the mail goes out I will rememebr to dial in
PROPOSED: to meet Tuesdays 9:30am Boston time for 60 to 90 minutes,
starting 16 May 2006 until further notice
<SteveH> 2nd'd
regrets ericp, afs for 16 May due to XTech
RESOLUTION: to meet Tuesdays 9:30am Boston time for 60 to 90
minutes, starting 30 May 2006 until further notice
EricP to scribe 30 May
post-hoc action added by the scribe and former chair...
<scribe> ACTION: EricP: to notify adminreq of the change in meeting
time [recorded in
[16]http://www.w3.org/2006/05/09-dawg-minutes.html#action01]
JSON results format status
EricP: I expect to get this done tomorrow.
<scribe> ACTION: EricP to publish

punctuationSyntax: bnodes in predicates
KC: I saw mail from Steve today
DanC: looked for records re: disallowing bnodes in predicate
position
... couldn't find any explicit decision to that effect
... As of 11 Nov, bnodes were in
change was made in 1.629 2006/01/30 17:38:14
patH: may have last come up under rdfSemantics issue
<Souri> [19]suggestion from Pat to take it out
[19] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0305.html
hmm... we RESOLVED "that SPARQL QL editor's draft 1.623 section 2.5
addresses issue rdfSemantics and is sufficient to postpone issue
owlDisjunction", and bnodes are out there.
<kendall> SteveH: I remember discussion of this, colleagues suggest
that the restriction is somewhat confusing
<DanC_> I thnk I should edit the issues list to show that the 26 Jan
decision re rdfSemantics also affects punctuationSyntax
<kendall> DanC, I'd be happy for you to do that.
SH: I'm getting feedback that prohibiting bnodes in Verb is
inconvenient
EricP: there's [something involving * that the scribe didn't really
catch]
AndyS: it would change the semantics...
PatH: yes, it might work, but then it wouldn't work with OWL...
... but OWL might change in that direction too.
SH: there are approved tests that are relevant
AndyS: those tests don't test the semantics
<scribe> ACTION: AndyS to find tests with bnodes in predicates and
mark them as syntax errors (and unapproved until we approve them)
[recorded in

[22] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/att-0298/26-dawg-minutes.html
KC: how do we re-sync editors drafts with published TRs?
DC: well, you can ask to do an updated CR, or go back to WD, or ask
for PR
<DanC_> [24], Test/grammar question Geoff Chappell (Thursday, 6
April)
[24] http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2006Apr/0002.html
<DanC_> (I see Andy answered him, though we haven't done the [OK?]
dance. dunno if we need to.)
valueTesting
<kendall> ACTION: Kendall to mark valueTesting as open on issues
list (i.e., to really learn how to handle issues list) [recorded in

test suite maintenance
DC: my action went to Andy in the last meeting.
<AndyS_> ACTION: AndyS: to draft of open-world = tests [CONTINUES]
[recorded in
[27]http://www.w3.org/2006/05/09-dawg-minutes.html#action07]

yes, DONE, ACTION: EricP and Jeen to fix OPTIONAL coding
comments on RIF use cases
KC: still interested?
PatH: yes, still interested; no progress yet
... ah... 2 weeks is during WWW2006, so more like 30th
<DanC_> [29]Sven's review of RIF Use Cases
[29] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006AprJun/0039.html
<kendall> ACTION: PatH to review RIF UC&R doc by roughly the 30th
May [recorded in
[30]http://www.w3.org/2006/05/09-dawg-minutes.html#action09]
mime type issues
<scribe> ACTION: EricP to respond to [$1\47]Dirk on MIME type stuff
[DONE] [recorded in
[31]http://www.w3.org/2006/05/09-dawg-minutes.html#action10]
<ericP> [32]http://www.w3.org/mid/20060421165157.GI26709@w3.org
[32] http://www.w3.org/mid/20060421165157.GI26709@w3.org
<scribe> ACTION: EricP to follow up on mime type requests, i.e. to
ask the W3C/IETF liaison to do the registration [CONTINUES]
[recorded in
[33]http://www.w3.org/2006/05/09-dawg-minutes.html#action11]
AFS: there's this stuff of \u escapes... ok, yes, separable from
mime types
punctuationSyntax, \u escapes
<AndyS_> [34]experience with \u escapes
[34] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0443.html
AndyS: when do escape rules apply?
<DanC_> (sounds like punctuationSyntax should get opened again
around \u)
<kendall> slow chair didn't follow much of that... hope someone did
:)
AFS: the layering between, e.g., \u and variable names is tricky;
breaks traditional parser layering
<DanC_> (I suggest you re-open punctuationSyntax to address comments
re \u escapes, KC)
<kendall> yeah, since that way I may figure out what the issue is.
:>
EricP: [something that sounded like a good test case, involving \u
in quoted strings]
<ericP> ASK { ?s ?p "hi \"mom\"" }
<DanC_> >>> hex(ord('"'))
<DanC_> '0x22'
<ericP> ASK { ?s ?p "hi \u0022mom\u0022" }
<kendall> Is that legal by the spec currently?
<DanC_> (regardless of what the answer is, it clearly merits a test
case)
<kendall> yes
AFS: yes, the spec gives an answer here, but one that is hard to
implement
PatH: indeed, I'd prefer that "hi \u0022mom\u0022" were treated as
"hi "mom"" which is not cool
EricP: this makes query generation a bit harder
<AndyS_> Example: ?a\u0020x
<kendall> it's obviously open IMO! :)
KC: ok, punctuationSyntax is open.
(anybody have a pointer to a relevant message from the comments
achive?)
<Souri> Question: Isn't "I said \"Hello World\"" a valid plain
literal?
<AndyS_>
[35]http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0
443.html
[35] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0443.html
<AndyS_> #Is this comment\u0020 legal
<ericP> # \u000d SELECT ...
AFS: consider the case of writing a query with kanji characters in
variable names from a us-ascii keyboard
<ericP> [36]http://www.w3.org/2001/sw/DataAccess/rq23/#escIRI
[36] http://www.w3.org/2001/sw/DataAccess/rq23/#escIRI
A.6 Escape sequences in IRI references, prefixed names and variable
names
<ericP> [[
<ericP> These escape sequences are not included in the grammar
below. Only escape sequences for characters that would be legal at
that point in the grammar may be given. For example, the variable
"?x\u0020y" is not legal (\u0020 is a space and is not permitted in
a variable name).
<ericP> \\
<ericP> oh weak, no close bracket
DanC: note while this \u stuff looks wierd, but it's the result of a
negotiation with the I18N WG
EricP: I'm more worried about backslashes in comments than [missed]
REQUEST FOR TESTCASE [ # \u000d SELECT ... ]
<scribe> ACTION: AndyS write tests for \u details [recorded in
[37]http://www.w3.org/2006/05/09-dawg-minutes.html#action12]
<AndyS_> NB // This is not legal Java \u because the \u is illegal
<AndyS_> NB // This is legal Java \u0020
<SteveH> bye
<kendall> Do the bots need to be dismissed?
not really; they get bored and wander off after a while
<kendall> cool
