Re: [RDFa] Widgets Schema and an Example in RDFa + HTML

Hi Michael,
Thanks for the feedback. Although your idea is interesting, I have not
seen any widget engines that actually use RDF for the metadata format.
For the widget spec, we are following industry practices and I think
it would be too much a revolutionary step to require a widget engine
to have to process RDF.

Besides, if I had my way, I would do away with XML all together and
just to the manifest/configuration with simple JavaScript Object
Notation. I am not convinced that there is any real advantage in using
XML over other formats.
