How do the following rules of thumb sound? - If an activity involves only modifying a current state, with no regard for prior history, then it is "distributed authoring", and belongs on w3c-dist-auth. - If an activity involves prior history, such as dealing with a particular revision, or requiring metadata related to a change sequence, it is "versioning" and belongs on www-vers-wg. - If an activity involves querying or metadata that is not directly related to a revision history, then it is "document management" and belongs on www-vers-wg. I'd hope that authoring activities will turn out to be independent of whether one is also doing versioning activities, and that versioning may turn out to be a relatively simple (and hopefully standardizable :-) instance of document management techniques. Note that these categories are independent of the activity involving one or multiple resources, or being accomplished through one or multiple requests. -Dave
