Status of RDFa Syntax/Primer and CURIE spec
Ben: let's not discuss CURIE spec but I'd like a status update
Steven: the TAG asked for an extension of the comment period, which
we've granted
... so the actual deadline is the XHTML2 WG f2f at the Technical
Plenary week
Shane: we do have some editorial changes since the CURIE Last Call
which you'll find reflected in the editor's draft
Ben: anything the XHTML2 WG needs from us?
Steven: the SemWeb Deployment WG agreed to provide a comment as well
Ralph: and Jeremy has that action on behalf of SWD
Ben: RDFa Syntax has been approved to go to PR by both SWD and
XHTML2 WGs
... we're missing a response from AlanR on issue 122
... I neglected to ask the WG to explicitly vote to publish the
Primer
ACTION: Ben ask SWD to approve publication of an updated RDFa Primer
[recorded in
[32]http://www.w3.org/2008/08/28-rdfa-minutes.html#action20]
Ralph: what about NoahM's late comment?
-> [33]Ralph's proposed response to Noah
[33] http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2008Aug/0115.html
<msporny> +1 for clarifying that RDFa applies to XHTML.
Ralph: I propose an editorial change to the Abstract
<Steven> +1
Ben: maybe the point about subsetting the graph is not correct
anyway
... if a parser only produces part of the graph, it may not be doing
the right thing
Manu: we shouldn't say that it's OK to ignore triples
Ben: it would only be implementing half of the parser
Shane: it's easy to separate the philosophical issue from the actual
comment we have received
... the comment suggests that we move the processor conformance
requirements elsewhere
<ShaneM> [34]rdfa-syntax-20080905/#s_conformance
[34] http://www.w3.org/MarkUp/2008/PR-rdfa-syntax-20080905/#s_conformance
Shane: I disagree with this comment
... we have 3 subsections of our conformance requirements
... 4.1 talks about document conformance and is about markup
... 4.2 talks about user agent conformance
... 4.3 talks about processor conformance
... these are all necessary and are all fine as they are
... the philosophical discussion about whether it's ok to subset the
triples would be a 4.4 and we don't need to have that discussion
today
... the sort of processor we've talked about is one that gives you
all the triples
Ralph: I agree with Shane's separation of those issues
... don't engage in the philosophical debate about subsetting now
Steven: I think Noah is thinking about optimizations
... we don't need to say anything about this
... if an application optimizes away something and we can't tell
from the outside, it doesn't matter
... if the application produces the same results as one that did not
optimize, we don't care
... "as long as the output is the same as if the application had
produced the full graph, we don't care"
Ben: we just talk about producing the graph
Shane: technically we just talk about the processor
Ben: so the application is out of our scope
Mark: Noah may not be trying to distinguish between the application
layer and the processor layer
... however, the idea of the default graph runs through both the
language and the processor and I don't see a simple way to separate
these quickly
... I don't think the comment is so much about a distinction between
application layers and processor layers
Ralph: so a combination of Shane's 3 points and the idea that the
default graph is intertwined throughout makes us not wish to do a
major document rearrangement at this time
<Steven> I think in Noah's mail that he meant <prefix:html
xmlns:prefix="[35]http://www.w3.org/1999/xhtml" xml:lang="en">"
[35] http://www.w3.org/1999/xhtml
<ShaneM> New text: A strictly conforming XHTML+RDFa document is a
document that requires only the facilities described as mandatory in
this specification. Such a document satisfies the following
criteria:
ACTION: Ben add Noah's comments to the tracker [recorded in
[36]http://www.w3.org/2008/08/28-rdfa-minutes.html#action21]
Ben: I've already written the transform to produce the CR
Disposition of Comments
Shane: I've already integrated all of the changes proposed in
Ralph's message
HTML5/RDFa discussion
Ben: background on why this discussion is taking place now rather
than later
... Creative Commons has been working on the ccRel specification for
a while
... we decided to submit it to W3C to be published as a Member
Submission
... it got a lot of attention when W3C published it
... and it mentions RDFa
... so that started the discussion
<mhausenblas> [37]my 2c on the ongoing HTML5 discussion :)
[37] http://news.oreilly.com/2008/08/html4ever-or-the-next-logical.html
-> [38]HTML5 discussion
[38] http://lists.w3.org/Archives/Public/www-archive/2008Aug/
Shane: why isn't this discussion on the [39]HTML WG list?
[39] http://lists.w3.org/Archives/Public/public-html/2008Aug/
<ShaneM> been pondering HTML4 and RDFa - some noodling here:
[40]http://www.rdfa.info/wiki/RDFainHTML4
[40] http://www.rdfa.info/wiki/RDFainHTML4
ACTION: Ralph update draft response to Noah [recorded in
[41]http://www.w3.org/2008/08/28-rdfa-minutes.html#action22]
Manu: there's not a lot of understanding of RDF, RDF/XML, and RDFa
and the differences within the HTML WG; we're building an
understanding of the benefits of structured data in markup
Michael: I saw Guus' announcement [42]requesting PR transition
... should I update the implementation report now?
[42] http://lists.w3.org/Archives/Public/public-swd-wg/2008Aug/0086.html
<Steven> If all design was done by paving cow paths, no one would
ever build bridges
Ralph: sure, fine to add to the Implementation Report
... it will be useful to the Director when the PR transition
decision is made (next week)
Microformats.org using RDFa as expression language?
Manu: folk are getting tired of the problem that a new microformats
parser is needed every time a new microformat is created
... the question now being considered within the microformats
community is whether to reuse the RDFa attributes but not put URIs
in them
... what would we think about this?
Mark: I like the sentiment but I take issue with the specifics
... in a previous discussion we'd debated whether attributes ought
to have different meanings in different contexts and decided they
should not
... now we have a fixed list of values recognized in CURIEs when
they appear without a prefix
... it would not be too hard to make that list extensible by others
... e.g. "within this DIV, unprefixed names come from <somewhere
else>"
... would be a bridge between microformats and RDFa
Ben: I second that
... microformats repurpose some HTML attributes
... and the Accessiblity community raised issues with this; e.g.
misuse of @title
... as RDFa explicitly ignores other unprefixed values in CURIEs,
that's an extensibility opportunity
... but [for example] redefining @typeof would be a mistake
... if the goal is to get to a single parser vs. a
parser-per-microformat then our goal is to be sure that the markup
always means the same thing
... so let's work on that together
<Zakim> ShaneM, you wanted to discuss CURIEs and microformats
Shane: our reserved values are interpreted as URIs at the end of the
day
Manu: what microformats really cares about is to be able to write
@rel='title' without having to explain anything else
... their concern is that to have to add a ':' would be difficult to
explain to users
... the underlying implementation is less of a concern; it's about
the actual markup
Shane: we'll need to prioritize where we put our effort next and
this could be it if it gets the microformat community into the fold
more quickly
<markbirbeck> I believe the key to this is to make a really simple
'flip' in CURIEs (wish we'd thought of it before). Instead of
@rel="license" being an 'unprefixed' value, we should see it as
'unsuffixed'.
<markbirbeck> Then all we're concerned about is providing more and
more techniques for defining prefixes.
<markbirbeck> @xmlns was always seen as only one way to define a
prefix.
Manu: as long as there's someone from RDFa advising the microformat
community we should be in good shape
Ben: I appreciate Mark's foresight in pushing for RDFa to ignore
unprefixed values
[adjourned]
Michael: regrets for next week
ACTION: Manu to work with Microformats community to address RDFa as
unified markup for uFs. [recorded in

Ralph: I'm available next week but not the two weeks after that
