RDF in XHTML Task Force

 

<markbirbeck> Hi everyone. I've just sent my apologies, because I'm going to have to leave the office in about 10 minutes for school parents' evening. :)

<Steven> (and he smiles about ti)

We'll let our imaginations run wild as to what happened at SemTech 2009 :)

Steven, you were there, right?

<Steven> only on irc

<Steven> I'm scribing another call now

<markbirbeck> @msporny: It was everything we could have hoped for...and more. ;)

<scribe> scribenick: msporny

... We need to utilize telecon time better
... So, I'm going to concentrate on focusing more on moving us forward.

Ben: We may want to delay discussion on some things until we have a good proposal on the table
... We could end up discussing something for too long on the call and wasting time doing a group brainstorm
... let's forget the charter for today.
... Do you guys have feedback on the charter?

Manu: No

Shane: No

Ben: Then let's not talk about the RDFa IG charter.
... Looks like our priorities are RDFa IG charter first and creating an HTML+RDFa spec
... Let's look at the issues.

RDFa Signalling Mechanism

Manu: Sam Ruby requested that this be moved way up the list

http://rdfa.info/wiki/rdfa-in-html-issues#RDFa_Task_Force_Discussion_Order

Ben: If there are vendors that disagree with the notion that if something is served with text/html that it be parsed with html5lib?

<ShaneM> did you look at this: http://htmlwg.mn.aptest.com/htmlwg/rdfa-html/#sec_1.1.

<markbirbeck> Sorry I can't be there, but I had an idea on this: <link rel="meta" href="" type="text/html" /> That would allow you to (a) point to some other document as the source of RDFa (which is handy anyway), and (b) point to 'self' as the source of RDFa, which effectively means 'I contain RDFa'. It uses the same mechanism that the Linked Data world uses (@rel="meta"), but instead of the MIME type being RDF/XML, it's HTML.

<markbirbeck> Got to dash...bye.

<ShaneM> bye

Shane: Doesn't this come down to a dialect issue?
... If I use the announcement mechanism for HTML4, then I'm in HTML4.

Ben: The browsers already have to do this.
... So, how can we do anything other than "whatever HTML5 says for triggering HTML5lib"?

Shane: Whatever announcement mechanism you want is fine - RDFa shouldn't get involved in that aspect.

Ben: We should be loose about this - whatever DOM tree you end up with, you pass to the RDFa processor.

Manu: Right.
... I think Sam Ruby et al would be okay with that.

Ben: Mark's proposal is interesting
... Linking to yourself as meta is an extra flag that can make things more efficient for parsers...

Shane: That's not how I took that.
... I took it to mean, if I'm a follow-your-nose parser, I should follow that @rel... I can use it to point to myself.

Manu: I don't think we should have more signaling mechanisms.

<benadida> Manu: I don't think we need any more way to signal presence of RDFa.

<benadida> +1

Shane: More interesting is rel="meta" href="" and type="text/application+xml"
... you can force the RDFa processor to process as xhtml
... I think it's cool, and it would work - not that we should make that a best practice.

Ben: Somebody could put that in today, so we don't really need to say anything about that.
... It's an interesting thing to note, but we probably shouldn't do anything with it.
... Proposed resolution for this issue.
... We can't override what the HTML5 spec will say, so it's out of our hands how the model is built.

Manu: I think that should be good with Sam.

Cutting features for HTML+RDFa

Manu: xmlns: and XMLLiteral are the only two things that may need to be cut, but doing so for both of them is arguable.

Ben: I agree about XMLLiteral, xmlns: has no argument for it to be cut.
... The rules are inconsistent between XHTML and HTML.

Manu: xmlns: is toxic, it's a political issue, not a technical one.

Shane: XMLLiteral might not be an issue - it's in a DOM, therefore it can be serialized as XML.
... It's canonical when you get it into a tree model.

Manu: Agreed.

Ben: +1
... Editing the wiki to note these discussions...
... Meeting every week now, let see if we can make it.
