+1 RDF is not well supported by browsers or well understood by devs. ARIA is what people use for accessibility.

+1 to Rich & Steve I think RDFA will just add to confusion in the dev community.

RDF is understood / popular in academic circles and of course TBL for the semantic web but I don't think anywhere else such as general web dev community.

We dev is complex enough already - just see recent posts by PPK and Bruce Lawson :)

My experience is that many people simply don't understand RDF. It was a tremendous hurdle getting people to adopt and understand ARIA. Introducing yet another technology would be a significant undertaking.

Liddies proposal was to use RDFa whereever possible inplace of an aria extention
The simplese case would look like
<button type="button" property="http://scehma.org/coga/terms/save">default</button>
in place of

<button type="button" aria-function="undo" >default</button>


There are many ways to write it such as
<body vocab="http://scehma.org/coga/terms ">
<button type="button" property="save">default</button>
this might make it harder for simple user agents to parse and manipulate it.  I also think in some cases it makes it more complex to use.

I do not think  everything will work as RDFa such as aria-importance or aria-numberfree, so we would still be doing an aria extension.


I think we should look at the metadata  and see if there is a more RDF compatible way to write it. However the linked data inline should be only for easyread alternatives.

All the best
