I personally wouldn't mind having some precedents on how to deal with arbitrary subparts of a resource. There will be many more situations besides locking in which handling subparts will become useful. Two points I would like to stress: a) "Ranges", as in "byte-ranges", are too restrictive and implementation oriented for being really and generally useful. Can't we provide a more fuzzy and evocative term? b) Specifying the management of subparts as one of the requirements that WebDAV needs to discuss does not mean that solutions need to be invented anew. So I believe we should definitely state an agreeable requirement for managing partial resources, and then happily discuss on range URLs or RANGELOCK or whatever. As I have learnt the hard way from Yaron :-), we should keep requirements and implementation separated. We can have as many and as different requirements as we care, and the discussion needs to be on their justifications only. When someone proposes a solution, well, the relevant requirements should have been accepted already. Therefore, if eventually range URLs will be commonplace, we will find out that the requirement of partial locks is already and naturally satisfied by a plain lock on a range URL, and we won't need to deal with it any further. >Pro Range Locking - Steve Carter, Yaron Y. Goland, and Gregory J. >Woodhouse, >Anti Range Locking - Larry Masinter, Mark Day, and Fabio Vitali Er, it's not that I am anti range locking, I am anti locking tout court, as I believe we will have to face problems with *any* kind of locks, although I'll admit that problems with ranges will be more frequent than with other types of locking.
