Getting Feature correct and up to date is important, copying some of the text from Feature into Ref (when the former is better) is fine, but I have found the Feature document to be amazingly useful both in running my research group (where we often need to check real quick as to which feature is used for what as people come up the learning curve - i.e. knowing they want to make a local restriction, they look in feature, discover what to use, and then look in ref or guide for syntax or examples) and in promoting our langauge - especially in non-English speaking countries. During recent trips to Japan, for example, I pointed a number of people at Feature so they could see what our langauge was about, without them having to expend a lot of time and energy understanding it. Several are now using it regularly (including people at several large companies who have now decided to use OWL instead of XML Schema for their representation of vocabularies) and I believe that if they'd had to start with Guide or Ref, they might not have made the effort - Features motivated them to look at the other documents. I see no reason to reconsider the decision by the WG to have such a document, it is useful and augments the other documents. We go to recommendation with a full set of docs, and Features will point people to Ref, whcih has the syntactic details and to the semantic documents, so our recommendation will indeed have the details Jeremy points out we need. Again, we do need to catch features up with the three levels and the various issues we closed, but not to remove it. -JH -- Professor James Hendler hendler@cs.umd.edu Director, Semantic Web and Agent Technologies 301-405-2696 Maryland Information and Network Dynamics Lab. 301-405-6707 (Fax) Univ of Maryland, College Park, MD 20742 240-731-3822 (Cell) http://www.cs.umd.edu/users/hendler
