14:02:48 <Zakim> On the phone I see niklasl, Ivan, gkellogg, MacTed (muted), manu1, Steven
14:02:50 <manu1> zakim, who is making noise?
14:03:01 <Zakim> manu1, listening for 10 seconds I heard sound from the following: Ivan (52%), Steven (4%)
14:05:10 <manu1> Agenda: http://lists.w3.org/Archives/Public/public-rdfa-wg/2011Oct/0047.html

14:05:22 <Zakim> MacTed should no longer be muted
14:05:53 <manu1> Topic: ISSUE-108: Refine/deprecate Link relations
14:06:46 <MacTed> manu1: we're trying to figure out what link relations should be in initial context
14:07:17 <MacTed> ... HTML5 spec appears to define a couple of link relations in way incompatible to XHTML
14:07:30 <MacTed> ... depending on who reads
14:08:24 <manu1> +1 - I hate the stylesheet references as well
14:08:27 <MacTed> ivan: as HTML5 author, these relationships are troublesome and distracting, without much (any?) added value
14:09:18 <manu1> q+ to discuss HTML5 and XHTML1 @rel values.
14:09:39 <MacTed> ... HTML5 radically reduces @rel relationship choices vs XHTML1
14:10:14 <manu1> ack manu1
14:10:14 <Zakim> manu1, you wanted to discuss HTML5 and XHTML1 @rel values.
14:11:56 <ivan> q+
14:11:57 <niklasl> q+ to ask about backcompat
14:12:18 <manu1> ack ivan
14:12:23 <MacTed> manu1 sees 2 proposals --  1. create different initial RDFa contexts for HTML5 and for XHTML1; 2. drop all @rel when dealing with HTML5, but retain them when dealing with XHTML1
14:12:38 <MacTed> s/manu1 sees/manu1: sees/
14:13:54 <MacTed> ivan: major confusion likely if we keep all the @rel from XHTML1
14:14:00 <manu1> ack niklas
14:14:00 <Zakim> niklasl, you wanted to ask about backcompat
14:14:22 <niklasl> http://labs.creativecommons.org/2011/ccrel-guide/#License_metadata
14:14:32 <manu1> This is from our new charter, Ivan is correct in that we're allowed to make this change per the charter: "As exceptions to this general goal, some small non-compatible changes with regard to the defaults on XML Literals, as well as whether all reserved @rel/@rev attribute values would automatically generate RDF triples, may be introduced. No radical redefinition of the RDFa language is envisaged."
14:14:48 <MacTed> niklasl: Creative Commons advice...  against dropping all @rel, because they recommend @rel=license; see http://labs.creativecommons.org/2011/ccrel-guide/#License_metadata
14:16:06 <niklasl> http://www.whatwg.org/specs/web-apps/current-work/multipage/links.html#linkTypes
14:16:16 <MacTed> ivan: CC does advise this...  so we should probably keep that one, which is part of the HTML5 set
14:17:08 <MacTed> manu: being too aggressive isn't too big a deal, we can always add stuff back to the initial context document
14:17:20 <niklasl> .. interesting: whatwg also says: " For historical reasons, user agents must also treat the keyword "copyright" like the license keyword."
14:17:54 <manu1> MacTed: I'm concerned about taking everything out and then putting stuff in... if the initial context document is too volatile, it becomes a problem.
14:18:29 <MacTed> ivan: 14 entries in WHATWG's current list -- http://www.whatwg.org/specs/web-apps/current-work/multipage/links.html#linkTypes
14:19:26 <ivan> We should keep: author, license, next, prev, 
14:19:56 <Steven> q+
14:20:02 <ivan> We should drop: alternate, bookmark, help, icon, nofollow, noreferrer prefetch search stylsheet tag
14:20:16 <manu1> ack Steven
14:20:31 <MacTed> ... these definitely have value -- author, license, next, prev
14:20:31 <MacTed> ... these are questionable -- alternate, bookmark, help, icon, nofollow, noreferrer, prefetch, search, stylsheet, tag
14:20:58 <MacTed> Steven: don't see what the win is for making extra limitation
14:22:05 <manu1> q+ to talk about erroneous triples.
14:22:40 <MacTed> [General discussion about stylesheet and other @rel-generated triples - do they provide value? Arguments both ways.]
14:23:30 <manu1> ack manu1
14:23:30 <Zakim> manu1, you wanted to talk about erroneous triples.
14:23:56 <MacTed> manu: one pitfall is putting features in because they /might/ have a use in the future... we shouldn't put stuff in that nobody has used in the past 3 years and we don't think people will use in the future.
14:28:28 <ivan> q+
14:29:22 <MacTed> [Further discussion about value (or lack) of any data tied to these relations]
14:29:52 <ivan> We could just refer to this list: http://www.whatwg.org/specs/web-apps/current-work/multipage/links.html#linkTypes
14:30:09 <niklasl> q+
14:30:14 <manu1> ack ivan
14:30:15 <ivan> ack ivan 
14:30:17 <manu1> ack niklasl
14:30:58 <MacTed> niklasl: does initial context override @vocab?  or vice versa?
14:31:05 <niklasl> .. vocab="http://www.w3.org/1999/xhtml/vocab#”
14:31:11 <MacTed> manu: @vocab overrides the initial context - I don't think defining a default vocabulary is a good idea.
14:32:23 <MacTed> Ivan: I agree, we should not do that.
14:34:55 <niklasl> So, we could use the terms from here? http://www.iana.org/assignments/link-relations/link-relations.xml
14:38:03 <niklasl> q+
14:38:13 <MacTed> [ discussion about IANA registry list -- http://www.iana.org/assignments/link-relations/link-relations.xml ]
14:39:07 <MacTed> ivan: concerned with which URIs are assigned to each term in that registry, and whether the definitions linked from that registry list are correct/current.
14:39:44 <niklasl> http://bblfish.net/work/atom-owl/2006-06-06/AtomOwl.html uses @prefix iana: <http://www.iana.org/assignments/relation/>
14:41:00 <niklasl> .. vocab="http://www.w3.org/ns/link-relations#” - we could do that.
14:41:34 <MacTed> MacTed: +1
14:41:43 <niklasl> q+
14:42:51 <manu1> ACTION: Ivan to contact Mark Nottingham about a permanent URL to the IANA Link Type Registry for use in RDF - need URIs for the relation-names.
14:42:51 <trackbot> Created ACTION-100 - Contact Mark Nottingham about a permanent URL to the IANA Link Type Registry for use in RDF - need URIs for the relation-names. [on Ivan Herman - due 2011-10-27].
14:45:14 <MacTed> niklasl: sees need for some URI centralization 
14:45:42 <MacTed> ivan: for future, after advice from Mark Nottingham per ACTION-100

14:48:55 <Zakim> +ShaneM; got it
14:49:01 <MacTed> MacTed: +1
14:49:42 <MacTed> RESOLVED: Adopt IANA Link Type Registry terms ( http://www.iana.org/assignments/link-relations/link-relations.xml ) as terms that will be specified for the following RDFa 1.1 languages XHTML1, HTML5, XHTML5.

14:53:54 <manu1> ack ivan
14:54:06 <MacTed> [discussion of whether we've resolved all outstanding technical issues]
14:54:31 <gkellogg> q+
14:55:15 <MacTed> manu: Let's publish this WD, and tell people that this will be the last chance for changes (preventing a 4th Last Call)
14:55:58 <manu1> ack gkellogg
14:56:12 <ivan> q+
14:56:18 <manu1> ack ivan
14:56:23 <MacTed> ivan: there may be some URI issues due to shifts from profile to context... but mostly about how nice the URLs look, not about functionality, just cosmetic stuff.
14:57:48 <MacTed> TAG has a(nother) thread about what RDFa should say about fragIDs
14:57:48 <MacTed> manu1: We have inserted what they wanted into the spec, they can raise an issue later on if they want to do so.
14:57:48 <MacTed> ShaneM: We need to discuss Henry Thompson's issue, it's the last one.
14:58:32 <manu1> Topic: Support for integration with XML

15:01:11 <Steven> Steven: XHTML+RDFa uses modularization, which says use the xhtml: prefix, and ODF has done this
15:01:38 <MacTed> niklasl: using RDFa in XSLT requires an XML namespace prefix
15:01:56 <ShaneM> If the Host Language uses XML Namespaces [XML-NAMES], the attributes in this specification should be defined in 'no namespace'. (e.g., when the attributes are used on elements in the Host Language's namespace, they can be used with no qualifying prefix: <myml:myElement property="next">).
15:02:15 <manu1> scribenick: manu1
15:02:21 <ShaneM> If the Host Language has its own definition for any attribute defined in this specification, that definition must be such that the processing required by this specification remains possible when the attribute is used in a way consistent with the requirements herein.
15:02:49 <Zakim> -MacTed
15:04:48 <manu1> Shane: This is an issue - if you ran an RDFa processor on an XML document w/ @property, it would process it. How do people integrate RDFa into XML languages that either conflict w/ the RDFa attributes, or want to integrate it using an XML namespace?
15:07:53 <manu1> Manu: Yes, but the issue is - does anyone need this? Who will use XSLT+RDFa?
15:08:24 <manu1> Shane: The spec allows RDFa attributes to be in no namespace, and it allows them to be in the XHTML namespace.
15:08:37 <manu1> Gregg: Should RDFa Core say you should use the XHTML namespace?
15:08:45 <manu1> Steven: it may as well say that, use the same namespace... not ideal, but it's what ODF decided to do and we shouldn't go against that if we don't have to.
15:13:19 <manu1> PROPOSAL: Add text to RDFa Core 1.1 to allow RDFa attributes to be placed into a namespace, where the namespace MUST be the xhtml namespace.
