14:07:47 <AxelPolleres> ack sandro
14:07:52 <LeeF> (I don't think the RDB group needs a UC&R review from the SPARQL WG)
14:08:13 <SteveH> sandro: rif, today is the last day of the review period

14:09:38 <SteveH> AxelPolleres: update minutes
14:10:15 <SteveH> ... no resolutions, but base URI agreement on how it's addressed, proposed text from chime
14:10:31 <SteveH> ... will add example for when there no BASE in the payload

14:11:16 <SteveH> ... discussion about graph URIs er. ISSE-49
14:11:32 <SteveH> ... not sure what to do about URIs which [sth] when you reference them
14:11:52 <AxelPolleres> http://www.w3.org/2001/tag/issues#httpRange-14
14:12:30 <SteveH> ... want to point out that we dont want to discourage, we expect that some might allow HTTP and other protocol
14:12:30 <bglimm> bglimm has joined #sparql
14:12:56 <SteveH> ... want to say that it might lead to ambiguity, give general warning, point to TAG issue
14:13:03 <SteveH> ... how/can we do that?
14:13:20 <SteveH> ... can we reference a TAG issue in a Rec track document?
14:13:26 <Zakim> + +0186528aacc
14:13:33 <bglimm> Zakim, mute me
14:13:33 <Zakim> sorry, bglimm, I do not know which phone connection belongs to you
14:13:38 <AndyS> q+
14:13:42 <SteveH> ivan: I think the answer is yes, but not sure
14:13:46 <bglimm> Zakim, +0186528aacc is me
14:13:46 <Zakim> +bglimm; got it
14:13:52 <bglimm> Zakim, mute me
14:13:52 <Zakim> bglimm should now be muted
14:14:06 <SteveH> AndyS: the TAG findings aren't recs, what standing do they have
14:14:26 <SteveH> ivan: "TAG findings" - they have no other official standing
14:14:28 <AxelPolleres> Can we give it as an informal reference?
14:14:57 <SteveH> sandro: we can't normatively reference them, but can informatively
14:15:25 <SteveH> ... can't say "to find out how to do this look [at TAG finding]" cos it's not a Rec
14:16:03 <Souri> :-)
14:16:16 <sandro> Basically it's like with Turtle and CURIEs ---- we wanted the concept, but there was no REC, so we had to write it ourselves.
14:16:16 <SteveH> AxelPolleres: either quote text, or reference it informatively
14:16:34 <sandro> Yes, we do.
14:16:36 <AxelPolleres> normative and informative references.
14:17:05 <AxelPolleres> best solution is probably a combination.
14:17:07 <SteveH> AndyS: we take textual forms from Turtle, and include them in the document
14:17:22 <SteveH> AxelPolleres: explain possible ambiguity, and informally reference
14:17:37 <bglimm> But the Wuery spec says: This document uses the http://www.w3.org/TeamSubmission/turtle/ [TURTLE] data format to show each triple explicitly. 
14:17:50 <bglimm> s/Wuery/Query/
14:18:04 <AxelPolleres> ACTION: axel to convey summary to chime:  explain possible ambiguity, and informally reference TAG issue.
14:18:04 <trackbot> Created ACTION-255 - Convey summary to chime:  explain possible ambiguity, and informally reference TAG issue. [on Axel Polleres - due 2010-06-15].
14:18:29 <kasei> Zakim, mute me
14:18:29 <Zakim> kasei should now be muted
14:18:37 <SteveH> AxelPolleres: there's a red box in the document, it's enough to drop it
14:18:38 <Souri> s/chime/Chime/
14:18:49 <SteveH> ... discussion about other terms, and distinctions
14:19:01 <AxelPolleres> unclear "network-manipulable RDF dataset" and distinction from "graph store" and "endpoint" needs clarification
14:19:18 <AndyS> bglimm, that's for the data in examples; not the SPARQL syntax (although that isn't as formal as I'd like)
14:19:21 <SteveH> AxelPolleres: overall doc on good track
14:19:39 <SteveH> Topic: find possible slot for testcases call
14:19:44 <bglimm> Ah, I thought it is for the whole doc including where parts of queries
14:19:49 <AndyS> bglimm, c.f. "4.2 Syntax for Triple  Patterns"
14:20:19 <AxelPolleres> http://www.doodle.com/ctb2a6t3bxup8t4d
14:20:26 <bglimm> AndyS, I see what you mean
14:20:41 <SteveH> AxelPolleres: there are several actions on collecting testcases
14:20:51 <AxelPolleres> http://www.w3.org/2009/sparql/track/actions/191
14:21:11 <SteveH> ... would be helpful to have emails pointing to testcases
14:21:27 <SteveH> ... don't need to be formal, just want to track them
14:21:40 <SteveH> ... people are responsible for collecting them
14:22:11 <SteveH> ... david, Olivier, AxelPolleres have outstanding actions
14:22:26 <SteveH> ... make sure that you fill out the poll
14:23:04 <SteveH> Topic: Function Library
14:23:06 <AxelPolleres> http://lists.w3.org/Archives/Public/public-rdf-dawg/2010AprJun/0309.html
14:23:18 <SteveH> AxelPolleres: AndyS has added several functions
14:23:44 <SteveH> ... main question is what's open
14:23:53 <SteveH> ... put some more links about this
14:24:11 <SteveH> ... one question is what about xquery and xpath F&O, we have initial list proposed by AndyS 
14:24:11 <AxelPolleres> http://lists.w3.org/Archives/Public/public-rdf-dawg/2009JulSep/0244.html
14:24:25 <AxelPolleres> http://www.w3.org/2009/sparql/wiki/Feature:FunctionLibrary#Starting_Points
14:24:29 <SteveH> ... incorporated in wiki doc ^
14:24:38 <SteveH> ... and we have one more doc on the wiki
14:24:41 <AxelPolleres> http://www.w3.org/2009/sparql/wiki/Design:FunctionLibrary
14:24:51 <SteveH> ... also half baked
14:25:15 <SteveH> ... do we reuse URIs in F&O?
14:25:58 <SteveH> ... AFAIR, we have had some discussion about namespaces
14:26:16 <SteveH> ... keywords v's namespaced URIs
14:26:30 <SteveH> AndyS: I don't remember that dicsussion
14:26:39 <Zakim> -Sandro
14:26:41 <SteveH> ... there are some functions that dont exsists elsewhere
14:26:55 <SteveH> ... have to assign URIs
14:27:14 <Zakim> +Sandro
14:27:31 <SteveH> AxelPolleres: do we have a namespace already for the sparql F&O
14:27:44 <SteveH> ivan: I did set one up.
14:28:04 <SteveH> AxelPolleres: could look at initial draft
14:28:10 <ivan> http://www.w3.org/ns/sparql.html
14:28:36 <AxelPolleres> that should be fine...
14:28:53 <AxelPolleres> http://www.w3.org/2009/sparql/docs/query-1.1/rq25.xml#func-coalesce
14:29:10 <SteveH> ivan: it's obvious what you have to do to add more items
14:29:26 <SteveH> AxelPolleres: that would affect all the operators that are new in SPARQL
14:29:34 <SteveH> ivan: yes
14:29:49 <SteveH> AxelPolleres: things in §15.4 need URIs
14:30:10 <SteveH> ivan: I will update doc if you send me changes
14:30:29 <AndyS> For Ivan: http://www.w3.org/2009/sparql/docs/query-1.1/rq25.xml#SparqlOps
14:30:35 <kasei> ivan, might be nice to assert rdf:type sd:Function for the functions in /ns/sparql
14:30:43 <AxelPolleres> 15.4.14 COALESCE
14:31:42 <AxelPolleres> COALESCE, IF, IN, NOT IN, IRI, URI, BNODE, STRDT, STRLANG
14:31:44 <ivan> q+
14:31:57 <AxelPolleres> ack AndyS
14:31:58 <AndyS> ack me
14:32:24 <SteveH> ivan: better decided around a table with beer
14:32:31 <SteveH> ... new ones are all caps, old ones are not
14:32:41 <ivan> if, in
14:32:45 <ivan>  and not IF and IN
14:32:47 <AndyS> SPARQL is case-insenitive keywords (except for "a")
14:32:48 <SteveH> AxelPolleres: it would make sense to keep with what we had
14:32:52 <kasei> they're all case insensitive in the language, though.
14:33:18 <SteveH> AxelPolleres: it's difficult, for the short names we have camel case
14:33:20 <SteveH> q+
14:33:26 <ivan> ack ivn
14:33:29 <ivan> ack ivan
14:33:40 <kasei> yes. was just pointing it out because we don't have URIs for the old ones yet
14:34:20 <SteveH> ack me
14:34:23 <AxelPolleres> camelCase seems to be the URI candidates, capital used in the definition
14:34:35 <AndyS> Yes - the grammar uses UC for clarity.  Examples use same case as section name (usually)
14:34:35 <SteveH> capital used in grammar/examples
14:34:43 <Zakim> -NickH
14:34:49 <SteveH> AndyS, oh, sorry, thought it was UC in examples
14:34:56 <AndyS> "if" looks silly 
14:35:26 <AxelPolleres> notIn
14:35:36 <SteveH> +1 to ivan 
14:35:49 <SteveH> AxelPolleres: just make it uniform
14:36:01 <AxelPolleres> ACTION: ivan to buy beers in SF
14:36:01 <trackbot> Sorry, amibiguous username (more than one match) - ivan
14:36:01 <trackbot> Try using a different identifier, such as family name or username (eg. ivan, imikhail)
14:36:52 <SteveH> AxelPolleres: take this to mail
14:37:07 <SteveH> AndyS: are we putting the F&O set in this doc, or another, or somewhere else
14:37:26 <SteveH> AxelPolleres: extension to core functions which we endorse should be in Q document
14:37:36 <SteveH> AndyS: who's going to write it
14:37:46 <Souri> 15.4.21 example needs a closing paranthesis: STRDT("123", xsd:integer
14:37:49 <SteveH> ... it will take longer if I do it
14:38:01 <SteveH> AxelPolleres: what new text do we need?
14:38:12 <SteveH> ... do we need to add examples for all these functions
14:38:14 <AndyS> souri - already fixed (in my copy)
14:38:43 <SteveH> AxelPolleres: what's missing is the formulation, and adding examples [?]
14:38:44 <AxelPolleres> http://www.w3.org/2009/sparql/docs/query-1.1/rq25.xml#func-coalesce
14:40:08 <AndyS> http://www.w3.org/2009/sparql/wiki/Design:FunctionLibrary
14:40:21 <SteveH> AxelPolleres: not sure about issues around sequences
14:40:34 <SteveH> AndyS: functions in [uri] are directly relevant to SPARQL, no seuences
14:40:44 <SteveH> ... arguments all values that we grok
14:41:18 <SteveH> ... unclear what the proposed way forwards is about this list, how do we deal with rel. to F&O
14:41:24 <AxelPolleres> 3 options
14:41:25 <SteveH> ... see 3 proposals
14:41:39 <SteveH> ... 1) start from SQL
14:41:45 <LeeF> I think the 2nd of those proposals is the best
14:41:46 <SteveH> ... 2) import a speicific set
14:41:56 <SteveH> ... 3) point to F&O equiv
14:42:32 <SteveH> ... in one there are two URIs
14:43:06 <SteveH> AxelPolleres: LeeF thinks we should import a specific set
14:43:06 <LeeF> Is anyone wanting to advocate taking from SQL instead of XPath/XQuery ?
14:43:24 <SteveH> ... if we import we can change them slightly if needed
14:43:40 <sandro> (I'm wondering about taking from RIF, which took option 3.)
14:43:41 <SteveH> LeeF: not sure how much support there is to import from SQL
14:44:05 <SteveH> AxelPolleres: We have COALESCE and IF from SQL
14:44:12 <LeeF> (i'd be fine with that approach as well, sandro. I don't know that much about the RIF function basis.)
14:44:14 <SteveH> ... strawpoll on 2) vs 3)
14:44:16 <AndyS> Interesting -sandro - why did it do that?
14:44:28 <sandro> q+
14:44:33 <sandro> zakim, unmute me
14:44:33 <Zakim> Sandro should no longer be muted
14:44:44 <SteveH> sandro: story from RIF, having same debate
14:45:01 <SteveH> ... use URIs or make own, decided to make own URIs
14:45:16 <SteveH> ... needed to change semantics in a few places, watned to add a few things, users would like in same namesoace
14:45:24 <SteveH> ... operators don't have URIs anyway
14:45:28 <SteveH> q+
14:45:34 <AndyS> q+
14:45:39 <SteveH> ... should sparql and rif use same URIs
14:45:46 <SteveH> q-
14:46:04 <SteveH> ... sparql and rif could coalesce on common uris, and they're both RDFy
14:46:13 <SteveH> AndyS: where did you have to change the smeantics
14:46:22 <AxelPolleres> q+ to speak chair-hat off
14:46:30 <SteveH> sandro: hoping AxelPolleres would remember, something about sequences
14:46:48 <SteveH> ... sequences have unusual semantics
14:46:51 <AxelPolleres> erorrs, sequences, played a role
14:46:55 <sandro> zakim, mute me
14:46:55 <Zakim> Sandro should now be muted
14:46:58 <AxelPolleres> ack me
14:46:58 <Zakim> AxelPolleres, you wanted to speak chair-hat off
14:46:59 <SteveH> ... outside of that I don't remember the differences
14:47:06 <AndyS> q-
14:47:12 <SteveH> AxelPolleres: we had problems with errors too, no errors in RIF
14:47:30 <SteveH> ... what would we do with errors
14:47:36 <AndyS> SPARQL is F&O evaluation
14:47:43 <sandro> (I think the errors bit is not worth doing a different URI over, personally, but I'm not a formalist.)
14:47:55 <AndyS> ... with errors being an extension point
14:48:32 <SteveH> ... if we use own namespace we dont have to think about which ones are keywords, if it has a URI in sparql namespace it can be used in syntax
14:48:40 <AxelPolleres> q?
14:48:47 <sandro> q-
14:49:20 <SteveH> AxelPolleres: poll: keep F&O namespace, or give own [sparql] namespace
14:49:34 <SteveH> 1 - keep namespace
14:49:39 <SteveH> 2 - sparql ns
14:49:45 <AxelPolleres> 2
14:49:46 <pgearon> 2
14:49:48 <AndyS> Option 2 (reuse namespace + alloc a namespace for operators)
14:49:52 <kasei> 2 (mild preference, would like to see rif+sparql convergence)
14:49:56 <MattPerry> 2
14:49:56 <bglimm> 2
14:49:57 <SteveH> 1
14:50:11 <LeeF> 0
14:50:15 <sandro> 0 unsure.....
14:50:30 <AndyS> Option 1 (reuse namespace + alloc a namespace for operators)
14:50:47 <LeeF> Yeah, I agree with that
14:50:50 <LeeF> too many keywords :)
14:52:54 <SteveH> AxelPolleres: op: ones are things that can be moddled with + etc. [?]
14:53:02 <AxelPolleres>  op :  + -  ! 
14:53:19 <AxelPolleres> http://lists.w3.org/Archives/Public/public-rdf-dawg/2009JulSep/0244.html
14:53:22 <SteveH> "op:" has no namespace officially
14:53:37 <SteveH> AxelPolleres: we dont have a URI for them
14:53:44 <AndyS> yes - but what about writing "op:numeric-add(?X, ?Y)"
14:54:15 <SteveH> AxelPolleres: you have to write the short form in xpath etc.
14:54:50 <SteveH> ... datatypes depenends on how it's delegates
14:55:05 <AxelPolleres> http://www.w3.org/2009/sparql/wiki/Design:FunctionLibrary
14:55:23 <SteveH> ... not complete, but we should have op URI + shortcut
14:55:45 <SteveH> ... then shortcuts come from [sth]
14:56:01 <SteveH> ... should take to email, running out of time
14:56:02 <AndyS> My pref: complete Design:FunctionLibrary as a design then take to WG.
14:56:55 <SteveH> AndyS: I don't have any time in next 2 weeks
