(Of course, I've already written one for Dublin Core, but it doesn't quite cover all of DC 1.1 yet). > Also, to give compliance, do we really want to have both level and prose > level?

The purpose of RDF is it's machine readibility (it wasn't meant to be displayed), but it should be able to be readily converted into a display format using XSLT. The RDF language (SubADL) that I published to the list last night wasn't intended to be the default language for WCAG compliance assertions: that is up to this group to develop. Rather, it was an example for Mr. Loughborough to use on his page, and also constitutes a global guideline assertion langauge: adding proselevel might not be useful in asserting WCAG validity, but it might be in some other instances. In summation, it was just a case of me getting bored and hacking up a short RDF example. I only CC'd it to the list because I thought it might help in the development of ADL! The great thing about both RDF and m12n is that they are developers langauges and very easy to write: i.e. anyone (to a point!) should be able to do it, and if not then the languages have failed in their purposes. Of course that also enables groups like ourselves to come up with useful materials conforming to W3C standards *very* quickly indeed... Kindest Regards, Sean B.
