I don't think we're going to put in URL-hacking rules for fractional resources -- and I don't think that we should. Servers can provide whatever resources they want, and those may in fact overlap in terms of the _server's storage model_ -- but this requires no special support in the protocol. It will require a lot of work for the server, but that's it's problem. So essentially, I think Jim's first post is right (and Larry is right) there's no need to mention range locking in the requirements because it's a _result_ of support for resource locking -- for any servers that wish to create resources to represent lockable ranges. So we may have lockable ranges, but I don't think there's any reason that they need to be in the requirements, or the protocol explicitly. They need to be in the documentation for servers that need to provide sub-resources. -- David _________________________________________ David Durand dgd@cs.bu.edu \ david@dynamicDiagrams.com Boston University Computer Science \ Sr. Analyst http://www.cs.bu.edu/students/grads/dgd/ \ Dynamic Diagrams --------------------------------------------\ http://dynamicDiagrams.com/ MAPA: mapping for the WWW \__________________________
