Ben: Maybe irrelevant after Mark's email. We'll look at it next week

mh: Needs resolving for the test cases

<scribe> ACTION: [PENDING] Elias to send email to list with use case from IBM [recorded in http://www.w3.org/2006/12/04-htmltf-minutes.html#action10] [WITHDRAWN]

Test cases

-> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2007Aug/0015.html

mh: We did 29-33 last week, so all is well
... see last week's minutes

Ben: So I haven't caught up with emails yet.

Ben: Steven, please look at the test cases that we approved last week

<scribe> ACTION: Steven to check test cases 29-33 [recorded in http://www.w3.org/2007/08/16-rdfa-minutes.html#action09]

mh: Take a look at the wiki page

Ben: Any other test cases?

mh: All dependent on open issues

<scribe> ACTION: mh to add a test case for @src [recorded in http://www.w3.org/2007/08/16-rdfa-minutes.html#action10]

Issue 55

Ben: So rather than depending on the CURIE spec the proposal is that we hardwire the CURIE syntax into the RDFa spec

<mhausenblas> blog post on this issue

mh: This was an interesting blog

Mark: This blog convinced me that we need to mention CURIEs explicitely
... the author just talks about a mess, and we should show we have a good solution
... we have updated the CURIEs document with a better syntax so that we can either insert the text or refer to it, however we want
... we will be raising and promoting the document

Steven: There has been a suggestion we should have a CURIE session at the TP

Ben: I agree that this is the right technical solution. The problem is the politics

Mark: I don't think it is as bad as you think, but I don't mind if we don't argue about this one, as long as we don't resolve "we won't use CURIEs"
... especially in the light of SPARQL doing the right thing

Ben: If we include the text now, and come last call hope that people will say "Why aren't you referring to the CURIE spec?"

Mark: Good

Ben: So the question to be asked "Do we use QNames or CURIEs?" is answered at first with "We do not use QNames"

<mhausenblas> +1

Mark: And refer to the SPARQL case
... which uses the exact same entry in the IRI syntax as we do

<benadida> Propose to RESOLVE: RDFa does not use QNames for shortening URIs, as that is technically incorrect. We use the equivalent of CURIEs, exactly as SPARQL. We will include the definition of CURIES inline with the RDFa syntax, though we may eventually choose to refer to the CURIE doc instead.

Ben: So we use the equivalent of CURIEs exactly as SPARQL

Steven: Second

<mhausenblas> +1

Mark: Agree.

RESOLUTION: RDFa does not use QNames for shortening URIs, as that is technically incorrect. We use the equivalent of CURIEs, exactly as SPARQL. We will include the definition of CURIES inline with the RDFa syntax, though we may eventually choose to refer to the CURIE doc instead.

Issue 42

Ben: @src on img element
... We haven't voted; but we're going to try it in implementations
... to see what breaks

<benadida> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2007Jul/0209.html

Ben: The main idea is that @src will behave like @href

mh: With lower priority

Ben: We could decide that later
... So we need a test case, to drive the implementors

<scribe> ACTION: mh to write an img@src test case [recorded in http://www.w3.org/2007/08/16-rdfa-minutes.html#action11]

<scribe> ACTION: Ben to update the bookmarklet to handle img@src [recorded in http://www.w3.org/2007/08/16-rdfa-minutes.html#action12]

rdfa-syntax document

Ben: Status?

Mark: We are working on CURIEs
... next stop is the syntax document

Ben: As soon as possible we should have an editor's draft of the doc

http://www.w3.org/MarkUp/Drafts/#rdfa-syntax

Steven: We have a URL for the editor's draft

<mhausenblas> Michael: In -> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2007Aug/0134.html I asked about @resouce usage

Ben: I have been added to the CVS mails, and that's great

Steven: There are no differences yet to the current document
... it has only been entered into the XHTML2 pub system

Ben: On the primer, there are no massive changes needed, but there are a few
... for instance for @resource
... there is no resolution on instanceof yet, we need to move that one on

@resource/@href

<benadida> Michael's proposal: As per TAG finding httpRange-14 [5] the value of @href MUST be an information resource, and the value of @resource MAY be an information resource. RDFa authors SHALL use a URI that identifies a non-information resources for the value of @resource.

<mhausenblas> Michael: as of -> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2007Aug/0134.html

Ben: I disagree slightly
... it seems to be overstepping our bounds

Mark: I totally agree
... HTML doesn't say what can go in an href, so we shouldn't either

Ben: This seems more like a best practice than a MUST
... and maybe a wiki page on best practice would be a good idea

mh: This was a proposal to make things clear
... like we do with CURIEs
... but I'm happy with what you said

Mark: There is no difference between a resource and a non-resource
... I only wanted to make it possible to make a non-clickable reference to a non-resource

mh: It is an RDF issue, not an RDFa issue

Mark: The difference won't show up in the triples

Ben: I propose a resolution
... that we won't require this proposal, but that we will create a best practices document

<benadida> proposed RESOLUTION: we do not place restrictions on the URIs in @href and @resource, but we will create a wiki page of good practices for certain use cases.

Mark: Let's make sure the examples are in the primer, and not labour the point

<mhausenblas> +1

mh: I second

RESOLUTION: we do not place restrictions on the URIs in @href and @resource, but we will create a wiki page of good practices for certain use cases.

<scribe> ACTION: mh to create best practices wiki page [recorded in http://www.w3.org/2007/08/16-rdfa-minutes.html#action13]

<scribe> ACTION: Ben to work test cases 31 and 32 into primer [recorded in http://www.w3.org/2007/08/16-rdfa-minutes.html#action14]

xml:base

Ben: Mark's email looks like it is about greater context than XHTML 1.1

Mark: I tried to think of things we would want (rel paths, mappings, and lang) that it would be wrong for us to define
... since it should come from the host language
... xml:base comes into that category

Steven: I propose we say that URI processing is defined by the host language

Ben: So in XHTML 1.1 it would be the base element and not xml:base that applies

Mark: We should understand xml:base, but not impose it on langauges

<mhausenblas> Michael: XML Base is clearly defined in -> http://www.w3.org/TR/xmlbase/

Mark: The XHTML2 WG may add an xml:base module for use in other languages
... But we don't know what the application supports
... we have to process it if we find it

Ben: My application outsources the work to the browser
... it does the resolution for me

mh: Then you depend on the browser

Steven: What would Google do if it processed RDFa?

Mark: So in my processor I always process xml:base
... but you are suggesting that if I am not in XML mode, I have to detect what I *am* processing
... I can live with that

<mhausenblas> Michael: -> http://www.w3.org/2006/07/SWD/wiki/RDFaInHTML needs an update

Ben: So in XHTML 1.1 xml:base has no effect (assuming we can detect that it is XHTML 1.1)

<mhausenblas> +1

Ben: So resolved

RESOLUTION: in XHTML 1.1 xml:base has no effect
