<manu> scribenick: manu
Ivan: When does HTML+RDFa get published?
Manu: Today at some point...
RDFa Updates
Manu: Any updates from Mark?
Ivan: We have a book chapter on RDFa that we wrote.
... There is a book that Handler and Fentel and Dom?? which is
published by Stringer
... Handbook for the Semantic Web
... Collects usual technologies and presents them.
... Still being heavily edited, published sometime late 2009
Manu: HTML+RDFa being published later today
... @version and @profile are being fought in HTML WG
Ivan: @version and @profile are not mandatory
Manu: Right, but they're important for the default generation of
XMLLiterals
... We probably don't want to do it in RDFa 1.1
Ivan: That would be an incompatible change on RDFa 1.0
Shane: If there is no versioning mechanism, then we can't make the
change.
Manu: @profile was obsoleted in HTML5, so that creates an issue for
us
... So we have an HTML5 EPB spec for addressing the @version and
@profile issue.
Ivan: So we would be forced to not make backwards-incompatible
changes.
... I also don't like that by default new lines and other formatting
characters are saved.
... What about the xmlns: issue?
Manu: Microsoft seems to be backing it... but no proposal yet.
Discuss and approve Shane's errata text
Manu:Reserved word values and case-sensitivity

Shane: Wait... new feedback from Philip Taylor
... on XMLLiteral issue.
Manu: So, we might need to defer talking about the XMLLiteral issue
based on Philips feedback
Ivan: Ivan is right, it should be Exclusive Canonical XML if we are
going to do this
... Yes, it's a mess right now, so I'll try to explain clearly.
... It should be Exclusive Canonical XML if we are going to require
this.
... in my understanding, if RDFa Processors serialize the triples it
will depend on which serialization they use
... if they serialize into TURTLE, they have to use Exclusive XML
Canonicalization.
... if they serialize to RDF/XML, they don't have to.
... we have to be careful in the examples and the primer, that they
should be in Exclusive Canonical XML.
... there are some tests today that are more permissive than they
should be.
... RDF/XML spec says that XML Literals must produce a canonical
representation of that.
Manu: Do you think RDFa should place this in the spec, to ensure
downstream RDF tools don't have to worry about c14n.
Ivan: I think it places a burden on implementations that only
generate RDF/XML?
Shane: It's necessary because the triples that we generate should be
identical... if they aren't, it affects triple stores.
Ivan: I think it's good advice to give, but don't think it should be
a requirement...
Manu: It causes a problem when RDFa Processors are used to generate
RDF/XML which is then sent to SPARQL processors.
Ivan: I think we need feedback from developers before we make this
requirement.
Mark: I agree with both of Ivan's points.
... At the very least, I think we should look at what this means for
HTML+RDFa vs. XHTML+RDFa
... So, this might only apply to the XHTML version.
... We have to be very careful - because prefixes might not have
come from xmlns:, they might have come from @token.
Ivan: having something in the document that is advisory is a good
idea.
Manu: Would we feel okay with making this a recommendation, but not
a requirement?
Shane: I think it's Philips issue, primarily.
Ivan: How much work would it require to Canonicalize XML in your
implementation, Shane?
Shane: I need to look at the new spec Philip sent out first.
Manu: Ok, so we just need to change the RDFa Test Suite
