If we move all the versioning stuff into a special content-type that must be processed, versioning updates will be implemented differently from non-versioning updates. This will reduce the ability of versioning to work with legacy authoring environments, and _require_ special work for versioning to be supported at all. I think this violates some of the requirements, unless we remove PUT, define POST as "form-only" and make all updates use a content-type (w/ simple options that allow versioning). I liked the multipart/HTTP you suggested for transactions, but that's a CM and not a versioning issue. I think that we agree that CM support will not work well will legacy software, except insofar as we can support the update of single resources. -- David --------------------------------------------+-------------------------- David Durand dgd@cs.bu.edu | david@dynamicDiagrams.com Boston University Computer Science | Dynamic Diagrams http://www.cs.bu.edu/students/grads/dgd/ | http://dynamicDiagrams.com/
