I'm Harry Halpin, the Chair of the GRDDL WG [1] which links XML and
XHTML (including "microformats") to the Semantic Web in order to
facilitate the deployment of the Semantic Web.

 In order to prevent a "surprise" Last Call, I'd like for your WG to
know  that we are going to go, barring any final comments or problems,
to  request move to Last Call on or shortly after Feb 15th for the
following three documents:

 1) GRDDL Specification [2]
 2) GRDDL Primer [3]
 3) GRDDL Use Cases [4]
 
 We believe this technology is related to the DIWG WG as a GRDDL can be
considered a possible solution for a Semantic Enrichment for Device
Independence work item, which states that:

"Discussion with various groups, including WAI PF and MMI, has indicated
that there is a likely need for representations that allow authors to
express additional semantics associated with particular
components of a user experience" [5]

In a nutshell, GRDDL allows the use of "link" element in a XHTML header
to express a transformation of the HTML to RDF, which could then in turn
provide needed semantic enrichment. This requires only a minor addition
to the link element or namespace document of the XML vocabulary/XHTML
profile URI and the authoring of a transformation, which can often be
done generically for many XHTML pages.

We believe this is compatible with:

"
it is possible that one outcome might include a small number of markup
extensions that represent usage patterns so common that they should be
supported directly. Another and possibly alternative outcome might be
ways to annotate such usage patterns to indicate additional semantics.
As with other work items, DIWG will focus on using existing W3C
techniques wherever appropriate and will propose extensions only where
necessary. Any extensions proposed will use the modularity of the
underlying W3C technology." [5]


 We are interested in whether or not implementations of GRDDL on mobile
devices may contribute to these work item, and I hope it does.

thanks!
