Jeni, - I think the 'typing' issue is still unresolved. I continue to believe that allowing multiple types in microdata, either within itemtype or with a different microdata attribute, would be important, and any other solution (eg, schema.org/type) is just a hack. I realize that there is a stiff opposition to this, but it merits a line in the report. - is it worth referring to RDFa Lite?

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. > > [1] http://lists.w3.org/Archives/Public/public-html/2011Jun/0366.html > [2] http://dev.w3.org/html5/md/ > [3] http://dev.w3.org/html5/rdfa/ > [4] http://lists.w3.org/Archives/Public/public-html-data-tf/ > [5] http://www.w3.org/wiki/Html-data-tf > [6] http://www.w3.org/Bugs/Public/show_bug.cgi?id=14470 > [7] http://www.w3.org/Bugs/Public/show_bug.cgi?id=14114 > [8] http://lists.w3.org/Archives/Public/semantic-web/2011Oct/0113.html > [9] http://lists.w3.org/Archives/Public/public-html-data-tf/2011Nov/0051.html > [10] http://lists.w3.org/Archives/Public/public-vocabs/2011Nov/0022.html > -- > Jeni Tennison > http://www.jenitennison.com > > ---- Ivan Herman, W3C Semantic Web Activity Lead Home: http://www.w3.org/People/Ivan/ mobile: +31-641044153 FOAF: http://www.ivan-herman.net/foaf.rdf
