<kendall> minutes approved from last week's meeting
next meeting 12 Apr, DaveB to scribe, risks noted
continued without (much) discussion:
<scribe> ACTION: KendallC to work out remaining details in sparqlx.{rnc,xsd,rng}: expression syntax, order-by stuff continues [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action08]
<scribe> ACTION: [PENDING] KendallC to incorporate EricP's privacy text, salting to taste [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action15]
<scribe> [DONE] ACTION EricP: to propose to close valueTesting (bonus points for test cases, to EricP or others)
-> 11th hour datatype testing proposal
<kendall> some discussion of some of ericp valuetesting tests...
<DaveB> looking at SPARQL-DT-1-alg.sh
<kendall> HowardK been following along a bit on Eric's design
<kendall> (discussion of eric's sparql-dt-0)
<kendall> XQuery makes 42 int and 42 float True (I think? It promotes the int to float, apparently)
<SteveH> I think this test says that xsd:int(42.0) = 42 is true
<kendall> discussion of 11.1.1 of rq23
<DaveB> it's refering to http://www.w3.org/TR/xquery/#mapping
<Zakim> Yoshio, you wanted to ask if a != b is True if no assertion on a being equal to b or not is provided
<Yoshio> re: Eric's design, a != b should be True
<Yoshio> following fron link on "!" leads to XQuery fn:not, which would say so
<Zakim> DanC, you wanted to give the "datatype swamp" speech again
<kendall> danc tries to recruit someone to co-present Eric's design w/ Eric
<kendall> ah, Tuscany...
<scribe> ACTION: DaveB to work with EricP to clarify valueTesting proposal ETA 2 weeks [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action01]
<DaveB> EricP's proposal seems not to refer to http://www.w3.org/TR/xquery/#promotion Type Promotion of numeric types, which seems relevant. and has a typo or two re the 2nd test. [this is for my information]
<scribe> ACTION: HowardK to seek clarification on valueTesting w.r.t. differenced from XQuery [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action02]
<scribe> ACTION: PatH to review sort design [PENDING] [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action10]
not started...
<kendall> iirc, Kowari's itQL has sort
<kendall> Jeen says something about comparing blank nodes and literals (?)
Jeen: SerQL doesn't does offset/limit but not SORT, yet; due to requests, we're starting to have a stab at it
<kendall> er, iTQL, I should say.
<kendall> Versa also has sort.
<kendall> how few is "widespread", I wonder
Jos: ORDER BY doesn't make sense with CONSTRUCT
<DaveB> [['Using ORDER BY on a solution sequence for a result form other than SELECT has no direct effect because only SELECT returns a sequence of results, not an RDF graph]]
<kendall> order by only applies to SELECt -- we think!
"Using ORDER BY on a solution sequence for a result form other than SELECT has no direct effect because only SELECT returns a sequence of results, not an RDF graph. However, in combination with LIMIT and OFFSET, it can be used to return partial results."
<kendall> So, another proposal discussed where the prime designer or proponent isn't here. :>
<kendall> tricky
<SteveH> Yoshio, there isn;t a way to do that currently as far as I know
<bijanp> (Not quite OT, but related, may be helpful, i'm unsure how reliable or good, but: http://www.cs.umd.edu/Library/TRs/CS-TR-4611/CS-TR-4611.ps )
<Yoshio> Hmm, we do need for that function to show users, for example, the total number of documents hit
OPTIONS: 2 questions: 1 prefer to adopt this sort design (or something close) vs prefer to postpone. 2: probably object to postpone / object to this design or something close
pref this sort design: 1 1 1
pref to postpone: 1 1 1 1
oppose postpone: 1
oppose sort: 1
<kendall> KevinW says that some of the complexity in the sort design is linked to complexity in other issues
<Yoshio> in sorting we have an arbitrary ordering for the last resort, though
<kendall> UMD cares more about limit with "next 10" than we do about sort
<kendall> fwiw
<DaveB> ref http://www.w3.org/TR/rdf-dawg-uc/#u2.19
<kendall> fine-grained parsing of use cases that weren't intended to read that way
(limit/offset seems like a protocol thing)
<kendall> (er, that's off the record, I should have said!)
<kendall> (limit & offset were originally in teh protocol, but i removed them at andy's urging, as I recall)
PatH: limit/offset could be done with protocol tokens
<bijan> limit is in the language now, see 10.1
yes, bijan... we're discussing whether that's the design we prefer
<Zakim> Yoshio, you wanted to ask if there is a way (or need for tha way) to get just the number of the solutions and to say a project next to me deals with patent search, where user
<bijan> Ah, ok.
<howardk> for those interested, new version of XQuery WD is available at http://www.w3.org/TR/xquery/
<Yoshio> to ask if "03"^^xsd:integer < "1"^^xsd:integer (lexical form rule 4.1)
<DaveB> I think, yes it says that in the rq23
<Yoshio> Hmm, horrible, confusing at least
<DaveB> actually I can't tell since those rules may/only apply if operator:< can't be used
<kendall> There is reification syntax in rq23
<kendall> SteveH: the value of the current syntax is that it's "like" Turtle; so adding new stuff reduces that value
<DaveB> I'd agree with steve, jos
<scribe> ACTION: DanC to propose to close punctuationSyntax (again) sans <<reifiction shorthand>> [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action03]
<scribe> ACTION: [DONE] EricP to notify the WG of editors draft (or change of plans) [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action13]
poll: PROPOSED: to publish SPARQL QL editor's draft 1.290 as a W3C WD, with editorial and technical TODOs highlighted, with status ala "the WG is preparing for last call; while we do our internal review, the community is welcome to comment too."
<kendall> Yoshio, KevinW, HowardK, PatH, Kendall, DaveB, SteveH -- support pub'ing now
<DaveB> I found 2.4, 2.6 confusing in parts. 5.4, 9 defns baffled me. 2.7 & lots need section nos.
<kendall> Jeen does too
<kendall> JosD does by implication :>
<kendall> no one seems opposed to publishing it, more relevantly
<DaveB> (in typo land; 3.1 uri syntax wrong; 4.1 empty; 6.2 dc namespace urls wrong)
After discussion of if/how to say "we're getting close to last call", DanC is inclined to do another round internally first.
<scribe> ACTION: PatH to internal review of rq23, starting monday [recorded in http://www.w3.org/2005/04/05-dawg-minutes.html#action04]
<DaveB> reviewing just defns? or all?
KendallC offers to copy-edit, noting it will use all his WG time
