14:04:14 <AndyS> Query reviews from Birte and Matt
14:04:29 <AndyS> ... in email
14:04:37 <bglimm> no
14:04:40 <bglimm> I did it

14:05:29 <trackbot> ACTION-391 Review Query, particularly Section 18 closed
14:05:35 <AndyS> just waiting for LeeF now :-)
14:05:50 <AndyS> ... and Axel.  Spot the connection.
14:06:34 <bglimm> Zakim, unmute me
14:06:34 <Zakim> bglimm should no longer be muted
14:06:46 <AndyS> AndyS update reviews http://lists.w3.org/Archives/Public/public-rdf-dawg/2011JanMar/0421.html and http://lists.w3.org/Archives/Public/public-rdf-dawg/2011JanMar/0427.html
14:08:09 <LeeF> bglimm: 2 significant issues - no connection between EXISTS/NOT EXISTS and algebra & property paths break entailment extension mechanism
14:08:17 <LeeF> AndyS: re first, that's an omission
14:10:08 <AndyS> ... entailment doc was going to discuss entailment+prop paths -- still some discussion about what's in query doc.
14:10:31 <AndyS> Kendal : his org is not able to review the entailment doc.
14:10:45 <AndyS> LeeF: One view from Oracle (link?)
14:10:52 <bglimm> I can ask Bijan, but I asked in our group here and no volunteers :-(
14:11:18 <AndyS> ... will ask semweb coord group - maybe someone from OWL2.
14:11:47 <bglimm> I can also ask Ian whether he can think of somebody
14:12:01 <AndyS> ... do want 2 (+) reviews before LC 
14:12:06 <MattPerry> Oracle entailment review from Zhe Whu (http://lists.w3.org/Archives/Public/public-rdf-dawg/2011JanMar/0217.html)
14:12:11 <LeeF> ACTION: Lee to ask for pre-last call reviews of entailment doc from SWCG and OWL WG
14:12:12 <trackbot> Created ACTION-411 - Ask for pre-last call reviews of entailment doc from SWCG and OWL WG [on Lee Feigenbaum - due 2011-03-22].

14:14:06 <Zakim> + +33.4.92.38.aabb
14:14:08 <AndyS> Little email discussion after last telecon
14:14:20 <OlivierCorby> zakim, aabb is me
14:14:20 <Zakim> +OlivierCorby; got it
14:14:32 <LeeF> PROPOSED: The SPARQL 1.1 Service Description describes endpoints that implement the SPARQL 1.1 Protocol; it does not describe URIs that respond to the SPARQL 1.1 RDF Dataset HTTP Protocol.
14:14:32 <Zakim> +Sandro
14:14:36 <sandro> (sorry I'm late)
14:14:39 <AndyS> ... proposal is therefore the minimal case that service description covers protocol, not HTTP dataset protocol
14:15:07 <AndyS> ... anyone have concerns about this approach?
14:15:11 <LeeF> <silence>
14:15:19 <kasei> +1
14:15:20 <Zakim> -bglimm
14:15:38 <LeeF> RESOLVED: The SPARQL 1.1 Service Description describes endpoints that implement the SPARQL 1.1 Protocol; it does not describe URIs that respond to the SPARQL 1.1 RDF Dataset HTTP Protocol.

14:16:04 <AndyS> LeeF: Overview doc needs to point this out. 
14:16:25 <AndyS> Kasei: SD doc does not mention dataset protocol.
14:17:06 <AndyS> LeeF: make clear statement about what is described and leave to overview doc.
14:17:25 <LeeF> ACTION: Lee to make sure overview document is clear about (non-)relationship between service description and rdf dataset http protocol
14:17:25 <trackbot> Created ACTION-412 - Make sure overview document is clear about (non-)relationship between service description and rdf dataset http protocol [on Lee Feigenbaum - due 2011-03-22].
14:18:29 <AndyS> Topic: relationship bewteen URI of a graph store at which they can issue dataset protocol requests? 
14:19:04 <AndyS> LeeF: a bit unclear currently : not an issue in SPARQL 1.0 in practice,
14:19:20 <bglimm> Zakim, mute me
14:19:20 <Zakim> bglimm should now be muted
14:20:09 <AndyS> SteveH: /sparql/dataset and /data/dataset 
14:21:04 <AndyS> AndyS: Fuseki uses /dataset/sparql,  /dataset/update and /dataset/data (and /dataset)
14:22:37 <AndyS> LeeF: SD assumes you have a URI to GET to start process
14:23:56 <AndyS> LeeF: Leave as is for now there being no proposals
14:24:00 <LeeF> http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2011Feb/0013.html
14:24:09 <AndyS> Topic: More operations besides POSTing to a Graph Store 
14:24:22 <LeeF> """
14:24:23 <LeeF> However my comment relates to management of Datasets, not graphs. I
14:24:23 <LeeF> think it would be useful to be able to:
14:24:23 <LeeF> * Add/Remove Datasets
14:24:23 <LeeF> * Add/Remove Graphs from Datasets
14:24:23 <LeeF> The specification already discusses the addition and removal of Graphs.
14:24:25 <LeeF> """
14:25:26 <AndyS> q+ to ask why point 2 isn't always covered
14:25:29 <kasei> I don't understand what the first one means. How would you then use a new dataset if it's not a 'default' dataset?
14:26:03 <kasei> q+ to clarify datasets vs. SD
14:26:06 <AndyS> LeeF: We do not provide a lifecycle for datasets
14:26:09 <LeeF> ack AndyS
14:26:09 <Zakim> AndyS, you wanted to ask why point 2 isn't always covered
14:27:02 <AndyS> Leigh may have a model of a set of graphs that can be assembled in datasets
14:27:23 <LeeF> ack kasei
14:27:23 <Zakim> kasei, you wanted to clarify datasets vs. SD
14:27:54 <AndyS> Who's handling the comment?
14:29:20 <AndyS> Thread for LD-3
14:30:52 <AndyS> leeF: advice to Chime that the request isn't clear
14:31:08 <Zakim> -bglimm
14:31:19 <LeeF> AndyS: work in RDF WG on quads may enable Leigh's request in the future
14:31:21 <AndyS> AndyS: Some work in RDF-WG may impact this.
14:31:38 <Zakim> +??P5
14:31:39 <AndyS> LeeF: will follow up with Chime.
14:31:46 <bglimm> Zakim, ??P5 is me
14:31:46 <Zakim> +bglimm; got it
14:32:00 <AndyS> Topic: D-entailment canonicalization issue
14:32:41 <AndyS> Birte: problem is that there are multiple lexical forms for the same value.
14:33:10 <AndyS> ... no specification as to whether canonicalization should be done.
14:33:36 <AndyS> ... if no canonicalization done, may get multiple answers for same value.
14:34:05 <AndyS> ... and also issue as to which datatypes are supported.
14:34:26 <AndyS> LeeF: What is state of the art?
14:34:30 <SteveH> silence?
14:35:07 <AndyS> Birte: XSD numerical datatypes common 
14:36:11 <LeeF> AndyS: what about overlapping value spaces of decimal and double?
14:36:21 <LeeF> bglimm: XSD says that the value spaces are disjoint
14:36:44 <AndyS> LeeF: What are the options?
14:37:00 <LeeF> http://www.w3.org/2009/sparql/docs/entailment/xmlspec.xml#id0x0fec6340
14:37:40 <LeeF> bglimm: 1) remove D-entailment 2) require canonicalization and identify a set of datatypes
14:37:44 <AndyS> Birte: (1) remove d-entailment (2) require canonicalization + some datatypes (3) no changes to doc
14:37:45 <LeeF> AndyS: a fixed set of datatypes?
14:37:49 <LeeF> bglimm: no could be extended
14:39:16 <MattPerry> I would vote for option 2
14:40:55 <MattPerry> Oracle does it for most xsd types
14:41:23 <MattPerry> numeric, date, boolean, string
14:42:23 <bglimm> OWL 2 doesn't support xsd:date, just xsd:dateTime & xsd:dateTimeStamp
14:42:54 <AndyS> What's dateTimeStamp?
14:43:20 <AndyS> Canoicalization is done by a few systems - they do not claim D-ent
14:43:22 <bglimm> I would have to look it up
14:43:53 <MattPerry> Same at Oracle, we don't say anything about D-entailment
14:44:16 <MattPerry> just canonicalization
14:44:18 <AndyS> AndyS: e.g. <s> <p> 1 . <s> <p> 01 .
14:44:56 <AndyS> Birte: one triple counts for query answers
14:45:27 <bglimm> D-Entailment includes also RDFS Entailment
14:45:55 <AndyS> LeeF; D-ent only of interest to systems that do not canonicalize.
14:46:04 <AndyS> .. any such systems?
14:46:38 <AndyS> ... now understand better.  Take one week to survey and if too few, remove section.
14:46:45 <MattPerry> That's fine
14:46:50 <Zakim> -bglimm
14:47:06 <AndyS> AndyS: Acceptable.

14:47:41 <AndyS> AndyS: tests?
14:48:12 <AndyS> LeeF: some pending - maybe a "tests telecon" - some open actions on checking and extending tests.
14:49:01 <AndyS> LeeF: Repeat for encouragement - checking does not take too long.
14:50:30 <AndyS> LeeF: Semtech June seems a bit late for a F2F
14:50:56 <AndyS> ... could get together for impl report etc as we might be in CR

17:31:24 <LeeF> kasei, i'm (gasp) starting to look at the protocol document... are you around if I have some questions?
17:31:45 <kasei> yeah, mostly
17:31:57 <kasei> I'll try to keep one eye on irc
17:36:54 <LeeF> kasei, thanks. first question -- terminology - is "HTTP operation" accepted terminology for the combination of an HTTP request and response? and is the proper term for the arguments to the operation "parameters" (as in "query string parameters")?
17:37:36 <kasei> i don't know -- I think that's terminology I left in from the previous version.
17:37:48 <LeeF> ah ok. WSDL definitely talks about operations
17:37:49 <kasei> I *believe* that parameters is correct, though.
17:38:06 <LeeF> i'd kind of like to either define it ourselves or move away from it and prefer requests 
17:39:07 <LeeF> there must be a standard term for an HTTP request+response though
17:39:39 <LeeF> eh, i'll use operation and just define what we mean
17:40:57 <LeeF> kasei, do you have a strong preference for "SPARQL Protocol" vs. "The SPARQL Protocol" ?
17:41:04 <kasei> no
17:41:43 <LeeF> ok, i strongly prefer "The" :)
