Absent: Ralph, DanBri
GRDDL Stuff
Ben: I talked with DanC this week about GRDDL
... we would like to add a GRDDLY transform somewhere
<MarkB_> Ben asked if the XHTML schema would live at the namespace URL
address.
<MarkB_> Steven said no decision had been taken yet.
Steven: Maybe
... depends on content negotiation
Ben: we could specify a GRDDL transform in the head of the HTML doc
that lives at the end of the NS URI
Steven: Sounds fine
Proofreading Ben's reply
Ben: Is my usage of RDF:bag OK?
Mark: We changed the inheritance rules, and haven't yet redrafted the
RDF/A document
... the example you gave had nested elements in an about, and I'm not
sure if that was the final version
Steven: I am sure we agreed to inherit the about
Mark: I need to check
... especially check the use cases in the rdf/a document
... IPTC are thinking of adopting rdf/a
... one of the examples that someone from IPTC showed asked how we
were going to do lists
... this was one of the reasons I wanted to put the rdf:bag stuff on
hold
... A new requirement from IPTC is the ability to use qnames in the
object as well as the properties
... and I think we do need to think about the bag/list stuff
... to avoid repetition
... One possibility is to rephrase the example that uses bags
Ben: can we give you an action?
Mark: Yes
<benadida> ACTION: Mark to check edge cases of inheritance in RDF/A
[recorded in
[10]http://www.w3.org/2005/06/21-swbp-minutes.html#action01]
Mark: If those are OK, we can tweak the example
Ben: I would like to resolve it before we reply, if possible
Mark: Part of the requirement from IPTC is to keep the markup short
... and consistency between how you refer to object and subject
... We could use a special character in hrefs, such as "[" to mark
qnames in href, or different attributes for the two cases, such as
href and qref
Ben: This is for brevity?
Mark: Yes, because their use cases adds MASSES of metadata
... and apparently in the WAI area this is also an issue
... One way would be to do something special with meta and link, such
as adding extra attributes, but not generalise those attributes,
allowing them only on those elements.
Ben: I think it would be good if IPTC adopted this, so we should
consider their requirements
<scribe> ACTION: Mark to create an rdf/a wiki [recorded in

Bnodes
Ben: I am convinced, I appreciate your summary

Ben: But would like more feedback from other members of the TF
<benadida> ACTION: Ben to put together the "ACID" test for XHTML2

IPTC
Mark: Another IPTC requirement
... was that they would have many attributes from different namespaces
on one element

/0024.html

http://lists.w3.org/Archives/Public/public-rdf-in-xhtml-tf/2005Jun/0024.html
Mark: we could make any 'foreign' attribute a predicate
... this would then work with other attributes within XHTML2
... such as media type
Ben: This sounds a little worrying
Steven: It might break backwards and forwards compatibility
... since attributes might mean different things between different
versions of XHTML2
Mark: Well, it's only metadata; it shouldn't matter if it gets added
to the triple store, even if it means something else as well
... the problem is working out what the content of the foreign
attribute is
Ben: I won't be able to come to the IPTC coordination meeting in July
... Eric Miller will be there
Mark: I have already talked with Eric about it
Steven: So have I; don't know if I can/will be there
Mark: Not clear for me either
Ben: We should coordinate with Eric
<scribe> ACTION: Ben chat to Eric about IPTC [recorded in
[15]http://www.w3.org/2005/06/21-swbp-minutes.html#action04]
Mark: Their issues are soluble; their higher level issue is whether to
use XHTML2
... instead of their in-house language
Interpreting author meaning

[16] http://www.w3.org/TR/xhtml2/mod-metaAttributes.html#sec_23.2.
Ben: The question is does the wording imply that a rel= implies an rdf
statement
?
Mark: Well, the idea is that you are making RDF statements whether you
like it or not
Steven: Would you like to replace "The metadata attributes can be used
to generate RDF statements." with
... The metadata attributes represent RDF statements.
Ben: Yes, that would be fine. I thought it might just be a wording
issue
... It is basically to do with author intent
... whether they really meant to say what we will extract in rdf
triples
... Are there examples where the author wouldn't be generating rdf?
Steven: Well rel="next" can be used by the user agent to automatically
go to the next document
... and the author may not have been thinking rdf
... but I see no harm in this also representing rdf
Ben: I want to avoid the situation where there could be any ambiguity
in whether the author really meant what is in the markup
<danbri> (vmtf overrunning...)
<benadida> please join us!
Mark: XHTML2 reserves all unprefixed values
Ben: So any prefixed values mean nothing in XHTML2, and can only be
interpreted as RDF
Steven: I think we need to say that there is an equivalence regardless
of prefix
... I don't see why it matters
Mark: I'm trying to think of how to word it without being too
proscriptive (for instance to allow flexibility in the use of
rel="next")
Ben: That brings us to the question of DanBri's schema, and our action
item
Steven: Well, most of the questions just bring up questions in my
mind, so I would rather discuss it
Ben: We will discuss it next week then
... Steven/Mark, would you please send suggested wording for 23.2 to
the mailing list?
Steven: OK
