Report on W3C Presentation

Ben: I presented a version of my Semantic Technologies talk to the W3C Staff last week. This version had more demos and technical detail. There was a lot of interest in seeing how this would work as an XHTML 1.1 module; there is interest in deployment issues for existing browsers

Steven: redefining 'rel' became an issue

Ralph: I think redefining 'rel' is a backwards compatibility question

Mark: 'rel' values without prefix are in the XHTML namespace, and there won't be anything at the URI. HTML has been that way (nothing at the URI) for years, so what's the problem? The layered approach is good and should be emphasized

Ben: Mozilla liked the changes to 'rel'

Ralph: a key message in Ben's presentation is the benefit that comes from putting RDF statements in the same document with the hypertext

Mark: someone has posted a suggestion to use RDF/A to markup text values in an RDF/XML OWL document. He noted that he needed to invent a namespace for the RDF/A attributes in order to do this. The specific task was wanting to identify medical terms in the text; see ~November 2005 in SWBPD list

[post-meeting, scribe finds "RE: [RDFA] Use within RDF" relevant to the use case Mark described]

Ben: the mnemonic "DRY" - Don't Repeat Yourself -- was suggested for the goal to not repeat data between RDF and display

XHTML 1.1 Module

-> Mark's draft of module

Mark: I found I had to create more new modules rather than just override existing ones. I tried to resolve all the issues; e.g. CURIEs in href. I am not sure what we should try to release first; perhaps just META and LINK everywhere and QNames in 'rel'. Clicking on a link that contains '[...]' is trickier

<Zakim> benadida, you wanted to talk about next WG

Ben: there is interest in having an XHTML 1.1 module proposal to be input to the proposed SemWeb Deployment WG. In that sense, having a complete proposal is good; can now start looking at how much of it could be deployed

Mark: if there's a good case for implementing the whole thing, I'd much prefer that

Ben: there will be concern for folk who choose not to upgrade their browser for a while

Ralph: is the XHTML 1.1 [modularization] specification being reopened for change to accommodate Mark's draft proposal? I'm a neophyte in XHTML 1.1 stuff.

Steven: don't get confused by the "1.1" numbering of both XHTML and XHTML Modularization

Mark: I'm only saying that the changes needed to META and LINK are so fundamental ... what Modularization expects you to do is create a layer that redefines things in the modularization. E.g. to add 'about' you go to 'common.extra' and simply add your attribute. The architecture is designed to make it easy to add elements and attributes. You're not supposed to need layers unless you want to fundamentally alter the architecture and I decided that such a fundamental change was appropriate

Steven: yes, Modularization does provide an extension mechanism but you cannot, e.g. add 'href' to 'common.extras' because you'll get duplicate href definitions

Mark: I only had to modify existing definitions for A, LINK, and imagemap. I found I had to make more changes to the schemas than I would have preferred to make

Ralph: so everything you needed to do to add RDF/A as an XHTML 1.1 module can be done without a WG in the HTML Activity making changes to existing XHTML specs?

Mark: right, the existing specs are enough to support this work

Steven: we've learned that attributes should not be hardwired to specific elements. Modularization does not allow a local attribute to be generalized; this is the one feature we didn't consider, so this makes href more difficult

Mark: we need to discuss how this moves forward; e.g. 'name' is currently required and needs to be made optional. With that change, a new document might not be conformant to an older schema

<Zakim> RalphS, you wanted to ask how best to keep records of the early modularization work on W3C site

Ralph: Mark, please email snapshots of your pages to TF mailing list or to www-archive@w3.org. We could also use W3C Wiki

<Steven_> url of pages?

Mark: there is a 'print' button that will print all the pages as a single document. Note, too, that comments are enabled on the skimstone site

Proposals on Some Outstanding Issues
