<msporny> 1) Action Items

<msporny> http://www.w3.org/2008/01/10-rdfa-minutes.html#ActionSummary

<msporny> 2) Chaining completion by @href and @src: what is everyone's take on this?

<msporny> 3) non-prefixed RELs: putting aside the issue of *which spec doc* the

<msporny> reserved words are defined in, for now, it's probably worth voting on

<msporny> Manu's proposal, if there is enough of a quorum:

<msporny> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2008Jan/0152.html

<msporny> I vote yes.

<msporny> 4) Test Cases: any updates we need to cover?

Parsing rules

Manu: Regarding Syntax document
... establishing subject

Mark explains current processing with hanging

Manu: For example @resource vs, @about (feedback from one of the developers)

Mark: One starts learning a new language should start with basic stuff as 'I want triple'
... IMO we have to explain it well rather than removing features (even if verbose)
... we have basically agreed on chaining, so if we are about to remove features
... we would end up with a bunch of exceptions

<Ralph> [apologies for tardiness]

Mark: When preserving legacy values, one has to take care of the whole picture

Ralph: Also author awareness is an issue
... this is a new language, but people familiar with previous languages should not get into too much trouble

Steven reminds on the topic

Manu: Sent out three questions to the list
... so there are two more
... <img />
... @src setting the subject
... and cases where it doesn't

Mark: In my model, every attrib can be subject/object
... so far no distinction between @about, etc.

Manu: One has to understand the processing model to 'get it' what happens

Mark: @src issue does not fundamentally touch my model

Implementation report

-> http://www.w3.org/2006/07/SWD/RDFa/implementation-report/ IR

cf http://www.w3.org/2001/sw/DataAccess/impl-report-ql SPARQL implementation report

Michael: my idea was to run the test cases and report which tests pass and which fail
... is it necessary to have a call where all those listed in the table can participate?

Michael: on hold TC http://www.w3.org/2006/07/SWD/wiki/RDFaTC#head-0b21a2e0fed4fecba83df959548e4a4f7b2bb45c-7

-- tests 2 & 3

Michael: 2 and 3 have meta in the body, which is not allowed in this version of RDFa, so we'll drop those

<mhausenblas> +1

-- test 4

Manu: test 4 -- we've also decided to disallow xml:base, so test 4 should be dropped

RESOLUTION: drop tests 2 and 3

Mark: I'd thought we'd made xml:base optional
... but I'm sure the answer is in the spec

<markbirbeck> "If a language includes @xml:base [XMLBASE], an RDFa parser for that host language must process it, and use its value to set [base]."

-> http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2008Jan/0014.html Re: Test Case #73: @about with relative URL using XHTML @xml:base

Michael: so we could change test 4 to show that no triples are generated

x/the generated triples ignore xml:base/the generated triples ignore xml:base/

Manu: the href needs to change to illustrate this?

Michael: I'll fix test 4 to show what should be generated, with xml:base ignored

-- test 16: Blank node, explicit

Ralph: what was test 16 supposed to test?

Michael: see comment from Elias -- apparently tests @about referring to a bnode
... propose to drop 16

Manu: test 64 tests bnode ref in a more atomic way

RESOLUTION: test 16 dropped
