(not two doc read in) 15:57:03 +1 15:57:03 PROPOSAL: Resolve ISSUE-40 by adding text to RDF Concepts, per the “Updated Proposal” from http://www.w3.org/2011/rdf-wg/wiki/Skolemization#Updated_Proposal 15:57:04 +1 15:57:06 +1 15:57:09 +1 15:57:10 +1 15:57:14 +0 15:57:15 +1 15:57:16 +1 15:57:18 +0 15:57:21 Andy, yes. 15:57:28 +1 15:57:30 +1 15:57:32 +1 15:57:34 +1 15:57:52 Guus: we can close issue-40 now 15:57:55 PatH: so bnode in subgraph shadows bnode in supergraph? 15:58:01 issue-12? 15:58:01 ISSUE-12 -- Reconcile various forms of string literals (time permitting) -- open 15:58:01 http://www.w3.org/2011/rdf-wg/track/issues/12 15:58:10 guus: where to start? 15:58:12 Take this bnode thing offline, guys. 15:58:20 +1 PatH 15:58:28 Yes please 15:58:57 What do we want the type of "foo" to be: plainliteral, xsd:striong, something else, or no type? 15:59:02 http://lists.w3.org/Archives/Public/public-rdf-wg/2011May/0230.html 15:59:48 PatH: looking at all the debates, I think people have different positions on which is the desrible solution 16:00:04 ... we should get it clear and take a binding decision 16:00:11 q+ 16:00:34 guus: I think you are saying that once we are clear on this, the other issues will follow 16:01:06 cygri: kind of agree. we should start to agree on the behavior, and then on the machinary 16:01:20 ... maybe we should go back a bit 16:01:44 ... if we have "" and ""^^xsd:string, are they the same? 16:03:14 I don't think there's a clear message from SPARQL 16:03:29 AZ has joined #rdf-wg 16:03:34 Yes, sparql clearly treats seems to have decided on xsd:string. 16:03:38 No objection to Lee's answer from me 16:03:41 Guus: can we live with that? 16:04:19 PatH: there are reasons for people to tream "jt"@us "jt"@fr as different strings 16:04:28 Currently datatype("foo") = xsd:string datatype("foo"@en) = error [and an extension?] 16:04:42 ... it is odd to see datatype changes when there is a language tag 16:04:59 ...added 16:05:09 mmmm 16:05:35 s/"jt"@us "jt"@fr/"chat"@en and "chat"@fr/ 16:05:37 Hey, err, what about just forcing "" == ""@und? 16:06:18 @gavin: that would make "" != ""^^xsd:string, then 16:06:35 AndyS, does it explicitly say it's an error? http://www.w3.org/TR/rdf-sparql-query/#func-datatype 16:06:41 what about datatypes as used with skos:notation - a little like "language" no? 16:06:41 PatH: plain literal is now neutral in RDF 16:07:03 SteveH - yes - not mentioned in dispatch => no dispatch => error in basic SPARQL 16:07:12 AndyS, ok 16:07:17 PatH: i like strings too 16:07:20 -PatH 16:07:21 But plain literals without language tags are semantically the same as xsd:string. 16:07:52 +PatH 16:08:43 pfps: strings are strings, 01 is syntatically different from 1, I don't care 16:08:48 Could be expressed more clearly but there are lots and lots of such cases. Editorial. 16:08:49 q+ 16:08:51 @pchampin Yeah, I know. But why the heck is ""@en != ""^^xsd:string then? 16:09:11 @gavin, because it has a language tag. Strings don't. 16:09:24 it seems that ""@en is subtype of ""^^xsd:string ... 16:09:41 MacTed: +1 16:09:43 @pchampin Yeah :\ Ugh, hard to explain to programers 16:10:28 +q 16:10:28 in other words, ""@en is ""^^xsd:string plus a lang property 16:10:36 @en - syntactic sugar for ^^englishString 16:10:52 guus: we can take Lee's position for the moment 16:11:15 ack cygri 16:11:55 changing datatypes is NOT aesthetic... 16:12:30 PatH: we can leave the current syntax as is 16:12:45 q+ 16:12:48 The problem with xsd:string is that XSD (*all* of XSD) is RDF's extension mechanism for types. 16:13:04 foo (SPARQL Result format) matters 16:13:34 too revolutionary to suggest that there are no languages, they're just certain string-derived datatypes? 16:14:06 q- 16:14:21 AndY? 16:14:40 PatH: we should decide on which one we like and update the syntax 16:14:50 Languages matter - we see this used for which label to display in apps 16:14:51 strawpoll? 16:15:02 a strawpoll is a good idea 16:16:01 prefer plain literal 16:16:09 prefer rdf:plainLiteral 16:16:09 guus: +1 if you prefer plain literal or xsd:string 16:16:17 Im am unclear what we ar voting on. 16:16:19 prefer plain literal or xsd:string, but not rdf:PlainLiteral 16:16:27 Either no change, or simple literal 16:16:31 still unclear. 16:16:43 IS the question, what should be the type of "foo" ? 16:16:56 Unclear to me, due to the relation of xsd:string to the rest of XSD. 16:16:57 sorry 16:17:04 Straw poll on: in the abstract syntax, if we want to have a single representation for strings (with and without language tag), which would it be? 16:18:26 bye 16:18:28 bye 16:18:29 -yvesr 16:18:30 -cygri 16:18:30 -PatH 16:18:31 by all 16:18:31 -davidwood 16:18:33 -??P18 16:18:33 thanks 16:18:34 -koalie 16:18:34 -AndyS 16:18:34 bye 16:18:35 -MacTed 16:18:36 -pchampin 16:18:38 -Peter_Patel-Schneider 16:18:42 trackbot, end meeting 16:18:42 Zakim, list attendees 16:18:42 -Bjorn_Bringert 16:18:43 RRSAgent, please draft minutes 16:18:43 I have made the request to generate http://www.w3.org/2011/05/18-rdf-wg-minutes.html trackbot 16:18:44 RRSAgent, bye 16:18:44 I see 1 open action item saved in http://www.w3.org/2011/05/18-rdf-wg-actions.rdf : 16:18:44 ACTION: Guus to send a message to the mailing list [1] 16:18:44 recorded in http://www.w3.org/2011/05/18-rdf-wg-irc#T15-40-21 16:18:46 -gavinc 16:18:47 BNods offline conversation at some point would be helpful! 16:22:41 RRSAgent has joined #rdf-wg 16:22:41 logging to http://www.w3.org/2011/05/18-rdf-wg-irc 16:22:45 chair: Guus 16:22:53 RRSAgent, please draft minutes 16:22:53 I have made the request to generate http://www.w3.org/2011/05/18-rdf-wg-minutes.html MacTed 16:23:08 RRSAgent, bye 16:23:16 RRSAgent, make logs public 16:23:19 RRSAgent, bye 16:23:19 I see no action items
