15:09:26 <davidwood1> ISSUE-64, RFC 3066 or RFC 5646 for language tags?
15:09:26 <davidwood1> Richard's proposal to resolve: http://lists.w3.org/Archives/Public/public-rdf-wg/2011May/0441.html
15:09:26 <trackbot> ISSUE-64 RFC 3066 or RFC 5646 for language tags? notes added
15:09:44 <AlexHall> davidwood: Richard has proposal to resolve language tag issue
15:09:52 <AZ> AZ has joined #rdf-wg
15:10:05 <JeremyCarroll> q+ to express surprise at the current text
15:10:14 <AlexHall> cygri: spec currently refers to obsoleted rfc 3066 for language tags
15:10:31 <AlexHall> ... proposal is to use latest rfc 5646
15:10:38 <davidwood1> Pat's reformulation/explanation: http://lists.w3.org/Archives/Public/public-rdf-wg/2011Jun/0010.html
15:10:56 <davidwood1> Lee F also expressed support: http://lists.w3.org/Archives/Public/public-rdf-wg/2011Jun/0011.html
15:11:10 <AlexHall> ... the new RFC has two notions of validity: well-formedness (grammar only) and validity (lang tag actually exists)
15:11:52 <AlexHall> ... add a note that the previous RFC allowed lang tags that are no longer allowed under the latest version
15:12:01 <ericP> +1 ref'ing 5646, +1 to holding at well-formedness, +1 to explanatory note
15:12:06 <yvesr> +1
15:12:07 <AlexHall> ... adopt the loosest notion of well-formedness
15:12:36 <AlexHall> davidwood: do you agree with pat's latest note on the mailing list?
15:12:49 <AlexHall> cygri: seems to be about a different issue
15:13:13 <AlexHall> davidwood: apologies, it was a different issue
15:14:23 <AlexHall> ???: when i read this note, it prompted me to drill down into original text around lang tags in the spec
15:14:57 <AZ> s/???/JeremyCarroll
15:15:03 <AlexHall> ... at some point there was a phrase to reference RFC 3066 or its successors
15:15:20 <AlexHall> ... not sure what that phrase was dropped, would like to find out why
15:15:39 <FabGandon> FabGandon has joined #rdf-wg
15:15:43 <AZ> s/what/why/
15:16:07 <ericP> refs to unicode serve as a precedent for "or it's successors", but there are contracts which allow forward-thinking parsers to know what could be valid in the next decade or so
15:16:25 <AlexHall> ... richard's point about validity vs. well-formedness was well taken and i support the proposal.
15:16:51 <davidwood1> http://www.w3.org/2011/rdf-wg/track/issues/64
15:17:03 <pfps> OK by me

15:21:10 <davidwood1> q?
15:21:39 <AlexHall> topic: Replacing URIref with IRI
15:21:47 <AlexHall> davidwood: This is Richard's text
15:22:24 <AlexHall> cygri: link is posted in minutes. issue is that we need to replace references to URI Reference in Concepts with references to IRI
15:22:48 <AlexHall> ... fortunately this simplifies things because IRI defines things which were previously defined in RDF
15:23:00 <AlexHall> ... main issue is what to do with the left-over notes in Concepts
15:23:29 <AlexHall> ... there are characters which were allowed in URIrefs which are no longer allowed in IRIs
15:23:37 <davidwood1> q+ to discuss IPv6 in ihost: http://tools.ietf.org/html/rfc3987#page-7
15:23:47 <AlexHall> ... add note to indicate that these are no longer allowed except in %-encoded form
15:24:21 <AlexHall> ... also a note to discourage %-encoded characters in old text, not sure this is a good idea
15:24:34 <AlexHall> q+ to discuss percent-encoding
15:24:51 <davidwood1> ack davidwood
15:24:51 <Zakim> davidwood, you wanted to discuss IPv6 in ihost: http://tools.ietf.org/html/rfc3987#page-7
15:24:59 <AlexHall> ... would like feedback from others who have looked into it
15:25:29 <AndyS> There is %-enc text in RFC => (summary) use % only as necessary and not wildly.
15:25:36 <JeremyCarroll> q+ to suggest editors' draft should be updated with new text and public review sought
15:25:47 <ericP> q?
15:25:52 <AndyS> IPv6 are legal using []
15:25:56 <AlexHall> davidwood: occurred to me since i'm dealing with IPv6 issues... IRI grammar seems to allow host names and IPv4 addresses but not IPv6
15:26:12 <AlexHall> ... anybody know why this is?
15:26:23 <AZ> AZ has joined #rdf-wg
15:26:26 <davidwood1> IP-literal     = "[" ( IPv6address / IPvFuture  ) "]"
15:26:31 <SteveH> right
15:26:34 <AlexHall> ???: IRI allows IPv6 addresses in square brackets
15:26:36 <SteveH> I've actually used them :)
15:26:46 <davidwood1> ack AlexHall
15:26:46 <Zakim> AlexHall, you wanted to discuss percent-encoding
15:26:50 <AndyS> RFC2732 adds them

15:28:22 <JeremyCarroll> q+ to say last note is too long!
15:30:23 <pchampin> is there any reference that we could refer to regarding this notion of "canonical IRI"?
15:30:27 <davidwood1> ack JeremyCarroll
15:30:27 <Zakim> JeremyCarroll, you wanted to suggest editors' draft should be updated with new text and public review sought and to say last note is too long!
15:30:50 <cygri> q+
15:30:56 <pfps> +1 to Jeremy - it is better to defer than to copy
15:31:34 <cygri> q-
15:31:36 <AlexHall> AlexHall: Intent of the original text with %-encoding seemed to be to avoid interoperability issues, so I agree with the new proposal in this regard.
15:31:48 <pfps> -1 to David - informative lists tend to become too normative
15:32:07 <cygri> q+ to ask jeremy how much is too long
15:32:14 <AlexHall> JeremyCarroll: Would like to simply defer to IRI section 5 for normalization
15:32:31 <AlexHall> ... giving a long list here runs the risk of people thinking this is exhaustive or normative
15:33:06 <AlexHall> davidwood: having the list there is nice as a summary so people don't have to hunt down the list themselves
15:33:26 <AlexHall> cygri: the intent here is that they are informative, not normative, and this will be explicitly noted in the document.
15:34:09 <ericP> q+ to propose adding "While RDF does not require normalization or IRIs, using only normalized IRI forms will improve the chances that non-RDF tools will consume and produce the same IRIs and that other parties will reproduce the exact spelling of these IRIs."
15:34:18 <davidwood1> q?
15:34:22 <cygri> q-
15:34:36 <AlexHall> JeremyCarroll: Historically this section has been note-heavy, would prefer to see this stuff moved into a new section 3.7
15:34:53 <Zakim> -AZ
15:34:54 <AZ> AZ has joined #rdf-wg
15:35:05 <pfps> moving to an informative section would help a lot!
15:35:25 <davidwood1> ack ericP
15:35:25 <Zakim> ericP, you wanted to propose adding "While RDF does not require normalization or IRIs, using only normalized IRI forms will improve the chances that non-RDF tools will consume and
15:35:29 <Zakim> ... produce the same IRIs and that other parties will reproduce the exact spelling of these IRIs."
15:35:38 <Zakim> +AZ
15:35:58 <AlexHall> ericP: seems the root issue is that producing non-normalized IRIs decreases the chance that other tools will produce the same form
15:36:12 <cygri> q+
15:36:15 <AndyS> And other RDF apps.
15:36:20 <JeremyCarroll> with that text we are well on the way to section 3.7
15:36:23 <davidwood1> ack cygri
15:36:36 <AlexHall> ... propose to add some text (quoted in IRC) to explain the motivations for this note.
15:37:08 <AlexHall> cygri: prefer to avoid motivations and give just a concise summary
15:37:34 <AlexHall> davidwood: would like to cater to people who don't want to read through all the specs to get a good understanding
15:38:02 <AlexHall> ... most conerns at this point seem to be editorial in nature
15:38:29 <AlexHall> cygri: as soon as the working draft goes live this content will be added and i encourage further comments
15:38:48 <AlexHall> ... don't think we need a resolution now but want interested people to keep any eye on it.
15:39:03 <AlexHall> Topic: Revisit RDF Postponed Issues
15:39:19 <AlexHall> davidwood: This always seems to get pushed down to the bottom of the agenda

15:49:50 <JeremyCarroll> close it, reject
15:49:54 <AlexHall> davidwood: instead of continuing, we should open it and revisit when we finish the specs
15:50:20 <AndyS> What would a more layered architecture look like?  It's not just change of exposition.

15:50:51 <AlexHall> pfps: we won't be addressing this in this WG
15:51:15 <AlexHall> ... there was a request for some defined fragment of RDFS that fits nicely into OWL

15:56:28 <ivan> http://www.w3.org/mid/C2088CAC-65A4-4B20-B657-C48A0440DE69@ihmc.us is pat's mail
15:56:48 <davidwood1> Ivan, that URI gives me a 404
15:56:52 <cygri> http://lists.w3.org/Archives/Public/public-rdf-wg/2011May/0430.html
15:56:58 <LeeF> Pat's email just re-expresses Richard's proposal, as far as i can tell.
15:57:02 <cygri> http://www.w3.org/2011/rdf-wg/wiki/StringLiterals/AbolishUntaggedPlain
15:57:03 <AlexHall> cygri: would not like to speak to what pat said, seems to just point out that the last proposal wasn't that complicated
15:57:21 <ivan> sorry

15:57:31 <LeeF> +1 to http://lists.w3.org/Archives/Public/public-rdf-wg/2011May/0430.html
15:57:36 <AndyS> Remaining issue is class vs datatype because DATATYPE("foo"@en) =? rdf:TaggedThing
15:57:37 <AlexHall> ... would like to talk about another proposal that addresses only strings without language tag
15:57:50 <AlexHall> ... seems to be agreement on this aspect of it
15:58:28 <SteveH> q+
15:58:58 <AlexHall> ... the proposal is to unify un-tagged string literals is to abolish the untagged plain literal in the abstract syntax and consider "foo" to be syntactic sugar for "foo"^^xsd:string in the concrete syntax
15:59:29 <AlexHall> s/is to abolish/by abolishing/
15:59:31 <AndyS> To Pat's email - if only class, then DATATYPE() => error still?? Seems unhelpful.
15:59:54 <AlexHall> pfps: like this proposal better than previous ones
16:00:46 <Zakim> -FabGandon
16:01:02 <AlexHall> ... have some compliant about the use of rdf:LangTaggedString, not sure it is needed and will require changes to RDF semantics, OWL, and SPARQL
16:01:22 <AZ> AZ has joined #rdf-wg
16:01:42 <FabGandon> FabGandon has left #rdf-wg
16:01:56 <JeremyCarroll>  rdf:LangTaggedString = rdfs:Literal - union of all typed literals
16:02:01 <AlexHall> ... thinks it's OK to handle rdf:LTS in OWL but need to verify
16:02:17 <davidwood1> ack SteveH
16:02:32 <AlexHall> ... would like to send a note to the OWL WG
16:02:54 <Souri> Question - Will "abc" still be a valid RDF literal? For example, would it be ok for me present the following triple for insertion: <John> rdfs:label "John" , OR am I obliged to present: <John> rdfs:label "John"^^xsd:string ? Also, can SPARQL query return "John" as a value for a variable?
16:03:02 <LeeF> q+
16:03:11 <AlexHall> SteveH: my concern is that we previously resolved to do just the opposite, to turn xsd:string into plain literals
16:03:26 <LeeF> q-
16:03:43 <LeeF> (was going to ask where this is visible, but then Steve answered it)
16:03:47 <Souri> I agree with Steve's concern
16:03:48 <AlexHall> ... this seems to match what users expect, since most string data in the wild is not typed as xsd:string
16:03:59 <AlexHall> ... there is also concern about how this plays with SPARQL
16:04:38 <AndyS> +1 - SPARQL results must return non-DT string for xsd:string for this else massive surprises (= lots of support costs).
16:05:00 <davidwood1> q?
16:05:15 <Souri> s/agree with/share/
16:05:18 <AlexHall> ... SPARQL results will return lots of unexpected xsd:string datatypes
16:05:33 <cygri> q+
16:05:45 <ivan> q+
16:05:51 <davidwood1> ack cygri
16:06:03 <AlexHall> ... seems odd to go to all this trouble to remove plain literals from the abstract syntax and turn around and strip out xsd:string types on the way out of the system.
16:06:05 <AndyS> q+ to say we can have both : syntax vs semantics
16:06:12 <pchampin> making a difference btw 2 kinds of strings is even more perverse
16:07:01 <AlexHall> cygri: the only syntax that really needs changing is N-Triples
16:07:15 <JeremyCarroll> q+ to suggest predictability also helpful for XML
16:07:40 <AlexHall> ... syntactic sugar in most concrete syntaxes is bad because it reduces predictability
16:08:23 <AlexHall> ... forbidding one datatype in the abstract syntax is even more perverse than forbidding plain literals in one of the concrete syntaxes
16:09:02 <sandro> SteveH, I liked deprecating xs:string until it looked like we could get rid of Plain Literals entirely (via using language-tags-as-datatypes).
16:09:25 <davidwood1> Sandro, right.  Me, too.
16:09:31 <ivan> q-
16:09:32 <davidwood1> ack ivan
16:09:35 <Souri> We could have both "abc" and "abc"^^xsd:string as equivalent (identical when compared), but treat the simple literal form "abc" to be the canonical one.
16:09:35 <AlexHall> davidwood: none of the proposals seems to play nicely with all the various levels (semantics, concepts, RDF document set, implementations)
16:09:37 <sandro> I hope people wont be expected to emit the long form.
16:09:40 <davidwood1> ack AndyS
16:09:40 <Zakim> AndyS, you wanted to say we can have both : syntax vs semantics
16:09:50 <SteveH> sandro, I like lang tag -> datatype
16:10:16 <AlexHall> AndyS: agree with Steve's concerns re. xsd:string in concrete syntaxes, think this could be abolished if we're careful
16:10:17 <AlexHall> ...
16:10:22 <JeremyCarroll> +1 to andy / split surface syntax from abstract syntax
16:10:29 <ericP> +1 to short-forms only in the serializations
16:10:39 <davidwood1> ack JeremyCarroll
16:10:39 <Zakim> JeremyCarroll, you wanted to suggest predictability also hel[ful for XML
16:10:43 <yvesr> +1 to AndyS 
16:10:51 <AlexHall> ... but we can split the abstract and sufrace syntaxes and use different approaches in each
16:11:00 <AZ> AZ has joined #rdf-wg
16:11:18 <AlexHall> Jeremy: If we're making N-Triples, Turtle more predictable then we should also make RDF/XML more predictable.
16:11:57 <AlexHall> davidwood: If we ingest RDF literals, turn them into xsd:string internally, and emit them back as plain literals, is this consistent with what you said:
16:12:13 <AlexHall> AndyS: yes it is, and I can't think of a format where you wouldn't want to do that.
16:12:30 <pfps> NO!
16:12:53 <AlexHall> davidwood: are we re-defining xsd:string?
16:12:57 <AlexHall>  everybody: NO!
16:13:39 <Souri> q+
16:13:41 <AlexHall> ???: we're retroactively declaring that all plain literals without language tags are actually xsd:strings
16:13:47 <sandro> At the RDF APIs will be much simpler, Andy.
16:13:55 <sandro> At LEAST, the APIs....
16:14:48 <AndyS> sandro - not so simple?? - are serializers inside or outside such API?
16:14:48 <AlexHall> davidwood: Volunteers to start a wiki page to collect all the places that are affected by Richard & Pat's ISSUE-12 proposal?
16:15:22 <AndyS> Request for a consolidate text for R+P proposal.
16:15:26 <cygri> http://www.w3.org/2011/rdf-wg/wiki/StringLiterals/AbolishUntaggedPlain
16:16:53 <AndyS> Please rename - if we keep untagged-in-surface syntax, it's a bad name.
16:17:08 <AlexHall> cygri: it's been my understanding that this conversation has been only about string literals without language tags
16:17:34 <AZ> AZ has joined #rdf-wg
16:17:39 <AlexHall> davidwood: can you combine this with the language-tag proposal?
16:18:06 <AlexHall> cygri: point was to keep them separate because there is still disagreement about language tags
16:18:45 <davidwood1> q?
16:18:51 <AlexHall> davidwood: request for somebody to add to the wiki page for this proposal a section that collects all documents which will need to change as a result of it.
16:19:39 <davidwood1> ack Souri
16:19:59 <AndyS> SPARQL query is doable / SPARQL XML results is not being opened this time => trickier
16:20:20 <AlexHall> souri: looking at this proposal, intent seems to be that these two forms are declared equivalent
16:20:45 <AlexHall> ... we should define a canonical form for the surface syntax so we know how to output the value in query results
16:20:59 <AlexHall> davidwood: we are over time
