RobS recently wrote: [[ With no definition of ordering, a "limit" feature violates many properties which can be desirable for a query language, including a simple desire for deterministic results. ]] -- http://lists.w3.org/Archives/Public/public-rdf-dawg/2004JulSep/0104.html and I have a similar feeling about DESCRIBE. If the results aren't determined by the spec, it feels like a very different beast from SELECT/WHERE. As chair, looking at WG mechanics, the test harness for DESCRIBE looks like it will be very different. EricP told me DESCRIBE gave him that "one of these things is not like the others" feeling when he was implementing it. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
