We have been thinking along similar lines. HiSoftware's interview toy deals with things that require manual checking (as I understand the press info) and defines an XML vocabulary for adding your own questions and appropriate responses. Nadia's MUTAT worked from RDF information. Dan Brickley worked on something similar (or worked with people who did) for more general school exam type stuff. In the early stages of EARL development we talked about whether it should encompass test questions as well. We decided not to do that - as I recall because we didn't know enough about what kind of questions we would be asking at the time. I don't think that is a bad decision - the fact that we settled on RDF means that we can relatively easily integrate a new vocabulary of questions (or even several different ones ;-). It seems to me that there would be some value in having an RDF version of the information available - this would enable you to compare tests you have to tests in other tools, and say "I don't need to ask tis question if there is an existing result for a question in MUTAT that covers it" (or maybe you do... let the user decide if they want to change the defaults). Of course there is no reason why you can't start from an XML schema and transform the information to RDF, or even have an XML schema that matches RDF syntax requirements... (No time to answer this properly here, but I thought I would add my thoughts since I had originally planned to write about this today). cheers Chaals On Mon, 17 Jun 2002, Nick Kew wrote: As you know, Page Valet incorporates a set of tests to evaluate documents against a set of guidelines such as WCAG or US Section 508. Further development using mod_xml now puts me in a position to generalise this. Instead of having hardwired tests, Valet should be able to read a spec from a schema, and so apply a user's own testsuite. The key change that makes this feasible is that mod_xml can precompile and cache a schema, rather than having to parse from scratch every time an evaluation is run (or hardwire it, as in the present Page Valet). Now I'd like to seek your views on how to go about this. Is an RDF schema a good option here, and what should it look like? Or would I be just as well-off with a semantic-free XML schema?
