Hello Harry, 

Thanks for the clarification. It just helps me know whether I need to find a reviewer or not.

Thanks also for pointing out the potential advantages of GRDDL over other approaches to semantic enrichment. You have definitely helped us with our semantic enrichment work item.

Thanks again and good luck with the last call.

Very best wishes

(trying to cc w3c-di-wg@w3.org).

I do not believe a formal review is needed as there is no dependency we believe between DIWG and GRDDL. However, we do believe that GRDDL might be of use to DIWG and we do believe that GRDDL as it stands fulfills our charter, which mentions DIWG [1].

"The Device Independence Working Group
<http://www.w3.org/2001/di/Group/> has a Semantic Enrichment for Device Independence work item <http://www.w3.org/2004/05/di-charter-2004-06.html#author-semantic-enrichment>
etc; the two groups should investigate whether implementations of GRDDL on mobile devices may contribute to these work item"

I think GRDDL is actually both more lightweight, requiring minimal or, and if the namespace document contains the transfomraiton, no change XHTML documents in order to retrieve semantics in the form of RDF from them.

However, HTML layout information is lost in translation to RDF ofcourse.
However, Ben Adida is working on a hGRDDL transform that transforms microformats -> RDFa+XHTML that keeps the HTML in place [2]. Hopefully there will be more progress on that front!
