15:06:09 <Zakim> +ShaneM
15:06:11 <manu> Knud: We should have a 5 minute break, halfway through the call.
15:07:49 <manu> Knud: What are we hoping to get through on the call today?
15:08:06 <manu> Manu: Hopefully, everything - next step for all issues should be an official WG response.
15:08:13 <ivan> zakim, dial ivan-voip
15:08:13 <Zakim> ok, ivan; the call is being made
15:08:14 <Zakim> +Ivan
15:09:16 <tinkster> I still can't get on call.  Will keep trying and participate IRC only for now. 
15:09:25 <manu> Topic: ISSUE-71: RDFa Core 1.1 LC comments from Shelley Powers
15:09:33 <tinkster> Could you skip over the issues I was triaging until I can get on?
15:10:11 <manu> Toby: http://www.w3.org/2006/tools/wiki/Zakim-SIP
15:10:24 <markbirbeck> Hi guys. I'm going to have a real problem this afternoon, I'm afraid. We have a release scheduled for tomorrow, and I need to be doing a lot of talking with other people. Would it be possible to keep an eye on IRC, and call in only if needed? That way I can still talk to people here. :)
15:11:06 <markbirbeck> (Yesterday we were ahead of schedule...today we are behind. :( )
15:11:27 <manu> http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Jan/0137.html
15:14:13 <manu> Shane: What about the accessibility issues?
15:14:58 <manu> Manu: We just need to make sure we're not doing anything wrong from an a11y standpoint.
15:21:00 <ivan> http://cmsmcq.com/mib/?p=1113
15:21:32 <manu> Shane: What about linking to triples?
15:22:06 <manu> Manu: It would be nice to forward-link to RDF-specific terms in all sections before section 3.

15:27:41 <manu> Shane: Ok, all looks good.
15:28:03 <manu> Manu: I will write the official response, then.
15:30:09 <manu> Topic: ISSUE-63: Case-insensitive term matching is non-deterministic at times
15:30:15 <manu> http://www.w3.org/2010/02/rdfa/track/issues/63
15:30:45 <manu> Manu: Shane's wording was: 'In the event that multiple terms are defined that differ only in case, it is undefined which term is matched when a reference is made which does NOT match case-sensitively.'
15:31:29 <manu> tinkster, any issue with the wording that shane proposed for ISSUE-63?
15:32:15 <tinkster> fine by me.
15:32:26 <ShaneM> I put this in:  <p class='note' id="C22" about="#C22" resource="http://www.w3.org/2010/02/rdfa/meetings/2011-01-20#ISSUE__2d_63__3a__Case__2d_insensitive_term_matching" rel='bibo:affirmedBy'>In the event that multiple <code>term</code>s are defined that differ only in case (e.g., 'Agent', 'agent', and 'AGENT'), if a reference is made which DOES NOT match case-sensitively (e.g., typeof='AGENt'), the results are UNSPECIFIED.</p>
15:33:42 <manu> Ivan: This is an issue where nobody will be completely happy, the text looks good, lets use it and move on from there.
15:33:56 <manu> Manu: Sounds good to me, let's move on.
15:34:14 <manu> Shane: I put this in the document already.
15:34:18 <manu> Ivan: This issue is DONE!
15:34:55 <manu> Topic: ISSUE-46: Should plain literals that match fully qualified IRIs be automatically converted to IRIs

15:35:46 <manu> Ivan: It came back up when handling Harry Halpin's LC comment: http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Jan/0121.html
15:36:22 <manu> Manu: People wanted to know if they could do this <meta property="foo:bar" content="http://example.org/baz" />

15:38:42 <manu> Manu: The people that we've been talking with have said that this is not a big issue for them.
15:39:07 <webr3> I'd assert: "people know what to expect by understanding what the property means" (which is how sem web should be, also)
15:40:16 <ivan> <html prefix="foo: URIFORFBNAMESPACE><head><meta propery="foo:FBPREDICATE".../>
15:40:22 <manu> Ivan: Ok, let's get a few more arguments on the table.
15:42:15 <tinkster> I have looked at a lot of implementations of Open Graph Protocol and they nearly *all* just search for the XPath //head/meta[property="og:foo"] (or its equivalent via DOM crawling)
15:42:44 <webr3> tinkster, likewise, true of almost every "curie" I've ever seen used outside semweb
15:44:07 <ShaneM> toby, are you saying that they are looking for a literal string?
15:44:24 <tinkster> yup
15:44:28 <ShaneM> wow
15:45:09 <webr3> ShaneM, that's v common.. from RDF to atom to opengraph and beyond
15:45:24 <webr3> rss* not rdf lol
15:45:46 <webr3> "dc:title" as a string token, not a qname/curie etc
15:45:55 <manu> Manu: ok, well I'll prepare a response to Harry on ISSUE-46
15:46:07 <manu> ACTION: Manu to prepare official WG response to Harry on ISSUE-46
15:46:07 <trackbot> Created ACTION-50 - Prepare official WG response to Harry on ISSUE-46 [on Manu Sporny - due 2011-02-08].
15:51:46 <manu> Nathan: I have a general concern about how this stuff is used in the field - don't people use IRIs in plain literals?
15:55:43 <tinkster> People do have valid reasons for putting IRIs (and things that look like they might be IRIs but might not be really) in plain literals. I've said before and I'll say it again, that Facebook's <http://ogp.me/ns#url> property takes a literal value quite sensibly.
15:56:32 <webr3> if you have http://example.org/foo in the wild, in @content an element, anywhere, people /expect/ it to be treated as a uri/url/iri
15:58:48 <tinkster> Maybe, but do they expect it to be treated as <http://example.org/foo> or as "http://example.org/foo"^^xsd:anyURI? They're different things - the latter is not just a funny way of saying the former.
15:59:50 <Knud> I think not only were spaces the problem, but also different IRI schemes. Pretty much anything /(.*?):(.*?)/ can be an IRI.
16:00:54 <webr3> "fb:me" matches that
16:01:14 <ShaneM> note that 'shane' is also an IRI
16:01:41 <tinkster> ":-)" matches that.
16:02:32 <ShaneM> heh.  http://www.w3.org/TR/xmlschema-2/#anyURI
16:03:17 <Knud>  there were suggestions to only accept certain IRI schemes, but I think people didn't like that back then.
16:03:34 <ShaneM> knud, you are right. 
16:05:09 <manu> Ivan: I think it was good that this issue was raised again, we cannot determininistically see whether or not something is an IRI - there is no way of doing that.
16:05:27 <manu> Manu: Also, keep in mind that there are other solutions to this problem, such as type coercion.
16:07:44 <manu> PROPOSAL: Response to ISSUE-46 should point out that there is no algorithm to deterministically identify IRIs.

16:14:47 <manu> If there is a deterministic way to determine an IRI, then our argument falls.
16:14:54 <tinkster> No, :-) doesn't match IRI - it just matches Knud's expression. (His regular expression, not necessarily his facial one.)
16:14:55 <manu> zakim, who is on the call?
16:14:56 <Zakim> On the phone I see Ivan, manu, ShaneM
16:15:05 <webr3> toby, lol
16:15:12 <manu> That may be his current facial expression - hard to know.

16:24:54 <manu> PROPOSAL: ISSUE-63 - case-insensitive term matching is non-deterministic.

17:04:53 <manu> RESOLVED: RDFa Core should include a Processor Graph Vocabulary and make Processor Graph support optional.
17:04:56 <tinkster> OKK.
17:04:58 <webr3> +1 (and if processor graph is present, must use grpah vocab)

17:06:59 <Knud> topic: ISSUE-67
17:08:25 <Knud> manu: is there some DOM spec that supresses whitespace?
17:11:19 <manu> http://www.w3.org/TR/xmlschema-1/#d0e1654
17:12:10 <Knud> shane: in XHTML whitespace must be preserved, in XML whitespace collapsing is permissable
17:14:40 <webr3> "white space preservation is defined by the host language"?
17:15:09 <Knud> tinkster: we should point that out in the spec, preferably with a reference (as manu put in)

17:21:50 <manu> http://w3.org/rdf-profiles/2014-rdfa
17:23:22 <webr3> "the rdfa profile may be updated in the future" ?
17:26:56 <manu> Every time you remove a profile, Shane kills a triple.
17:30:17 <manu> http://w3.org/rdf-profile
17:31:00 <Knud> webr3: The main problem is removing definitions from a profile, regardless of its URI or if we use a new default profile.
17:31:24 <ShaneM> <html profile='datedURIforProfile'>
17:31:32 <ShaneM> that's the only way to be sure
17:31:53 <Knud> … : People in their documents need to reference a stable profile
17:36:50 <manu> Manu: You can't remove or change any prefixes or terms in a profile at a particular URL. Appending is fine. If you have to change a URL, it MUST be backwards-compatible.
17:42:15 <manu> RDFa Core 1.1 => http://w3.org/rdf/profiles/2010
17:42:18 <manu> RDFa Core 1.1 => http://w3.org/rdf/profiles/2011
17:42:40 <ShaneM> youre not missing much
17:42:57 <manu> RDFa Core 1.1 => http://w3.org/rdf/profiles
17:43:15 <manu> RDFa Core 1.1 => http://w3.org/rdf/profiles/2011
17:43:23 <manu> The latest working prefixes/terms => http://w3.org/rdf/profiles
17:43:43 <manu> Nobody would ever use: http://w3.org/rdf/profiles - except for discussion on what the latest prefixes/terms should be.
17:43:54 <manu> RDFa processor implementations would ALWAYS use the dated URI
17:44:15 <manu> Nathan: We could just not define: http://w3.org/rdf/profiles
17:44:23 <ivan> if I understand things right I do not agree. An implementation that is caching would always use a non-dated URI
17:44:49 <ivan> dated uri for a default profile makes only sense if you want to keep to 'history'
17:45:03 <ShaneM> ivan - you are missing too much context 
17:45:09 <ivan> sorry...:-(
17:48:20 <manu> http://w3.org/rdf-default-profile
17:50:20 <manu> lots of discussion on approaches
17:52:21 <webr3> http://prefix.cc/dc
17:55:05 <webr3> I assert that "dc" can't go in the default profile, because it is ambigous
17:55:17 <manu> Why do you think it's ambiguous?
17:55:27 <ivan> webr3: this is something the DCMI people have to tell us
17:55:42 <webr3> -> http://prefix.cc/dc
17:55:59 <webr3> it's not what dcmi say, it's how the web population uses the string "dc"
17:56:04 <Knud> web3: this is based on how the prefix "dc" is actually used
17:56:30 <manu> xmlns:dc 
17:56:58 <Knud> but what do we set it to in the profile?
17:57:10 <webr3> yes, what Knud said
17:57:47 <ivan> this is something that the dcmi community have to tell us
17:58:03 <ivan> dcmi community -> DCMI as a holder of that vocabulary
17:58:21 <webr3> "dc:title"
17:59:35 <Knud> but webr3, if dc is so ambiguous, then we just cannot include it in the default profile at all
17:59:47 <webr3> yes, what Kund said again :)
18:00:06 <webr3> s/kund/Kund (sorry)
18:00:32 <Zakim> -ShaneM
18:01:54 <manu> Nathan: We need a default profile that processors should implement, if people want it to be stable, they must reference it directly.
18:02:04 <Knud> so this is not a technical problem we can solve, it's a social problem?
18:03:03 <webr3> we should encourage people to reference a stable profile if they want stability, and not /rely/ on the default profile
18:03:09 <Knud> what Nathan says sounds as though we should not have a default profile after all
18:03:34 <Knud> then the default profile is useless
18:03:35 <ivan> zakim, dial ivan-voip
18:03:35 <Zakim> ok, ivan; the call is being made
18:03:37 <Zakim> +Ivan
18:03:44 <webr3> as in, the default profile we provide for peopel to reference, not for people to depend on as having unambigous forever meaning (mapping of string to uris, we can't promise that, for social reasons)
18:04:53 <webr3> should I write it all up in a mail to the list?
18:05:54 <Knud> bye!
