 Ben: I don't think we have a new draft to give to the WGs yet :(

Next telecon in 2 weeks; 3 Jan

Ben: can we read the latest editor's draft to understand Mark's current thinking?

Shane: we haven't updated the public editor's draft yet, but can do so right now

<ShaneM> There is an updated rdfa-syntax draft at http://www.w3.org/MarkUp/2007/ED-rdfa-syntax-20071220/

Ben: can we review test cases usefully today?

Manu: with Mark's new interpretation, we'll have to review every case

Ben: I don't think Mark is intending to change the interpretation of current cases
... it's just floating @resource that would change
... I think Mark isn't proposing to change the cases with @about

[SWDWG] ACTION: Ben and Michael to address comments by Tom [regarding maintenance of wiki document http://www.w3.org/2006/07/SWD/wiki/RDFa] [recorded in http://www.w3.org/2007/10/08-swd-minutes.html#action05]

[SWDWG] ACTION: Ben to prepare draft implementation report for RDFa (with assistance from Michael) [recorded in http://www.w3.org/2007/10/08-swd-minutes.html#action03]

Ben: I was planning to wait until Last Call to do implementation report

Ralph: We have several implementations already, starting this now would be another way to advertise them.

[SWDWG] ACTION: Ben to update RDFa schedule in wiki http://www.w3.org/2006/07/SWD/wiki/RDFa#RDFa_schedule [recorded in http://www.w3.org/2007/10/08-swd-minutes.html#action04]

Ben: I keep updating it but it keeps getting out of date
... note that several of us will be at WWW2008 the end of April
... that's a good opportunity for publicity

Shane: I had raised a question about adding a value for GRDDL to @rel and @rev namespaces

Ben: GRDDL considered that to be in their namespace, not the HTML namespace
... so I think that's "above" us in the stack

Shane: ok with me

Test Case review

<msporny> Test cases to review for tomorrow

<msporny> RDFa Test Harness

-- test 47; @instanceof with @rel and @resource present, no @about

scribe: @instanceof not applying to @resource

Manu: the N3 comes from Ivan's parser which is not up-to-date, so ignore it for now
... focus on the XHTML and SPARQL

Ben, Manu, Ralph: test 47 looks ok to us

RESOLUTION: test 47 accepted, with a flag to recheck after Mark's latest rules

-- test 48; @instanceof with @about and @rel present, no @resource

<ShaneM> +1

<Ralph> +1

RESOLUTION: test 48 accepted

Ben: we don't expect 48 to change with Mark's rules

-- test 62; @rev in head using reserved, non-prefixed XHTML value

Manu: test 62 is @rev in HEAD

<Ralph>+1

RESOLUTION: test 62 accepted

-- test 52; @instanceof with @resource and nothing else

Ben: 52 is definitely affected by Mark's latest rules

<Ralph>+1 per my expectation

RESOLUTION: test 52 accepted, to be revisited after Mark's proposed changes

-- test 53; @instanceof with @resource and nothing else, with a subelement

Ben: this isn't the kind of markup someone would like write
... but if there were an @rel it would generate the given triples (plus another)
... so it's right

Ralph: I'm ok with 53

RESOLUTION: test 53 accepted, to be revisited after Mark's proposed changes

-- test 66; @about with @instanceof in the head

RESOLUTION: test 66 accepted

test 66 not affected by Mark's changes

-- test 67; @property in the head

<ShaneM> +1

defaulting subject in HEAD

RESOLUTION: test 67 accepted, not affected by Mark's rules

-- test 68; Relative URI in @about

Shane: how would I run these tests locally?

Ben: could add BASE in HEAD

<benadida> ACTION: Manu to check for BASE test cases [recorded in http://www.w3.org/2007/12/20-rdfa-minutes.html#action15]

<benadida> ACTION: Ben to propose a solution for running tests locally [recorded in http://www.w3.org/2007/12/20-rdfa-minutes.html#action16]

Ralph: test 4 is on hold, using xml:base

RESOLUTION: test 68 accepted, not affected by Mark's rules

-- test 69; Relative URI in @href

like test 68 with @rel and @href

Shane: calling these test files ".xhtml" will cause IE to not deal with them the way we want
... I will talk about this off-line with Michael and Manu

Ben: what does @about="" do in this case?
... is it necessary?

Manu: I'm not sure we have a test that defaults @about in the body -- I'll add one

RESOLUTION: test 69 accepted, not affected by Mark's rules

-- test 70; Relative URI in @resource

Manu: like 69 but with @resource

RESOLUTION: test 70 accepted, not affected by Mark's rules

@src

-> Rethinking @src in the context of chaining rules [Ben, 19-Dec ]

Manu: my only concern is that it would be simpler for developers to ignore @src
... but that violates DRY

Ben: I'm proposing that @src behaves just like @about, if both are present then @about supercedes

Manu: are there other HTML elements to which this would apply?

Ben: OBJECT
... but we care mostly about IMG

Manu: we're making a special case for IMG and OBJECT
... that's OK because folks do use IMG heavily
... but I wonder if there are other elements we should look at in the same way?

Shane: in XHTML2, @src works everywhere
... @longdesc might be another special case to consider

Ben: Mark had proposed that @longdesc become a [dc:]description
... which would argue in favor of @src being subject
... also, it's probably a good thing to have a story for inline OBJECTs
