I agree. Creating the next general-purpose successor to the RDF/XML syntax
is *not* what we're attempting here. We are fortunate with RDF in that
most tools (APIs, databases, query interfaces etc) don't care which
syntax was used, so developers and users are -to some extent- protected
from changes at the syntax level. And it might be that the world falls in
love with the XHTML2 RDF/A notation, and that some format derrived
from it becomes widely adopted in the marketplace, in preference to
RDF/XML. That's beyond our control. But also, isn't going to happen soon.
Talk of this taskforce seeking to "obsolete" RDF/XML is both unhelpful and
misleading; Bjoern, please stop it! If you prefer the RDF/A notation, feel
free to evangelise its benefits, contribute tools, test cases,
documentation etc., but don't go around casting FUD on the existing
standard. RDF/XML
is stable, well tested, and gets the job done for many applications.
