Oops, pushed the button too early: I think the work on the microdata->RDF mapping should be in the report, too, together with a reference to the current editor's draft. After all, this framed a majority of the discussion in the TF so far...

> The Task Force was put together by W3C in response to the TAG's note [1] about inconsistencies between microdata [2] and HTML+RDFa 1.1 [3]. Our goals are to perform a technical analysis of the relationships between microdata, RDFa and microformats with the goals of:

It may be that there are outstanding bugs when that happens, and it is likely that there will continue to be work to do to keep the guidance relevant if (as is likely) HTML5/microdata/RDFa change past that point. Part of the wrapping up of the Task Force will be recommending the appropriate groups to which to hand off that work.
