Hi Rich, thanks for your reply, I think we may be talking at odds here, because I was not specific enough: I don't see a problem with other technologies making use of the information provided via ARIA (for accessibility purposes), for more general purposes, but the addition of ARIA semantics by developers should not be *driven* by use cases other than for adding useful information about the UI to directly aid user interaction. Thus adding ARIA to HTML for Semantic Web purposes is a paradigm that needs to be be actively discouraged. For example use of ARIA semantics to add metadata for RDF processing purposes. -- Regards SteveF HTML 5.1 <http://www.w3.org/html/wg/drafts/html/master/> On 1 May 2015 at 11:50, Richard Schwerdtfeger <schwer@us.ibm.com> wrote: > Where my head is at on this is that people should look at ARIA semantics > to drive the user experience.
