Clemm" <geoffrey.clemm@rational.com> To: ietf-dav-versioning@w3.org Subject: Re: Comments on versioning protocol From: "Vasta, John" <jvasta@rational.com> 1.1 "LOCK/UNLOCK requests can be mapped into CHECKOUT/CHECKIN requests" is no longer true, right? Correct. I'll delete this statement. 2.1 Unversioned resources can also be created by MKCOL, COPY, and MOVE. Versioned resources can also be created by MKCOL and COPY. Rather than enumerate all the ways to create resources, I changed this to "e.g. by PUT". Does CHECKOUT really turn a versionable resource into a versioned resource? If so, it cannot create an initial revision which is a copy of the versionable resource, since it is still checked out (there won't be a revision until it is checked in). Fixed this to say that an empty initial revision is created, and that the versionable resource is copied into a new working resource. We had a thread not too long ago about whether we should create a null initial revision, or let you have an initial working resource that is not associated with any revision. I'll go with the "null initial revision" for now, but this is probably still an open issue. 2.7 How can a repository contain workspaces? Can a workspace contain resources from more than one repository? That's a good point ... workspaces and repositories should be orthogonal. I'll just delete the "workspaces" property from the repository resource. 3.4.4 If DAV:auto-version takes the same values as DAV:checkin-policy, then it does not seem possible to enable auto-version without having a non-default checkin-policy, since the only choices are "uncheckout", "overwrite", and "keep-checked-out". Good point. I've added a DAV:new-version value, which is the default. 3.7.2 If an rsr references another workspace, is it expected to always track the rsr of that workspace, or only copy it at the time the rsr is set? Another good point. In the spirit of "RSR simplification", I'll remove the statement that a workspace can be an RSR element. 4.3 Aren't "resource properties" gone now? Yes. I'll move this functionality to a "Property REPORT" which lets you get the properties of all the resources identified by property href's (in a single REPORT). 4.7 When the destination collection of BIND is a versioned collection, the new binding cannot be added to the target of the versioned collection; it must be added to a new revision of the versioned collection. Unless the target of the versioned collection is a working collection. Therefore, the destination must either be a working collection, or auto-versioning must be applicable. Yes. I'll cheat a bit by saying "BIND acts like a PUT on the Destination" (since PUT goes into gory detail about all this). (Should auto-versioning be allowed? Won't only versioning clients issue BIND requests?) BIND's can be issued by non-versioning clients that support the BIND extension. 4.8 Same comments from BIND destination apply to MOVE. (Also, fix copy/paste error: BIND should be MOVE.) Done. 4.X Still need to mention MKCOL. Done. 5.1 Shouldn't a precondition of MKRESOURCE for versioned-resources be that the parent collection is checked out? I'm tempted at the moment to just say that CHECKOUT is *always* used to created versioned resources (and not MKRESOURCE). Does anyone object? 5.6.2 I think the DTD for compare-report should be <!ELEMENT compare-report (added|deleted|changed)*> so that the child elements can appear in any order. (When used to represent the comparison of text files, it will be important to have them in "file order".) Done. 6.1 Why must workspaces have DAV:current-activity or DAV:current-label set? Seems like some simple clients will not want to worry about either activities or labels. Good point (I think Jim Amsden made this point as well). I'll delete this prerequisite. If anyone objects to any of these changes, please let me know (I can always back them out). Cheers, Geoff
