Hi, I'm looking for other parties that would be interested on working on DASL again. With the current status of the spec I have mainly two problems, both of which apply to the basicsearch grammar: 1) The spec is completely silent about how the grammar engine is supposed to know about data types. For instance, I would suspect that property values for getcontentlength are supposed to be compared as numbers, while getlastmodified need a date comparison. 2) The grammar for accessing properties is not really XML-friendly, which has led to inventions like "DAV:iscollection". Indeed, this so-called "synthetic property" only solves one special case and leaves the rest (lockdiscovery, attributes, deltaV computed properties) untreated. I think DASL needs a grammar which can do "arbitrary" queries into the attributes, so something with the power of XPath would need to be used. In addition, I'm not happy with the language in chapter 3 (discovery of grammars). It mixes namespace prefixes with URI schemes, which is only correct in the very special case of "DAV:" (being a URI scheme and also the prefix used there). Julian
