Today, HTTP and FTP (for example), interoperate. When the HTTP portion supports WebDAV versioning, there is now an interop problem. Although this is outside of the scope of this effort, I think we will avoid lots of questions and problems down the road if specify an interop story. The one I proposed seems simple and not burdensome on the server. IMHO that is... :-) Chris -----Original Message----- From: Tim_Ellison@oti.com [mailto:Tim_Ellison@oti.com] Sent: Thursday, October 07, 1999 7:00 AM To: ietf-dav-versioning@w3.org Subject: FW: A question on Versioning-unaware cl <chris> It seems to me, that if a server supports multiple protocols, then a "PUT" via a non-versioning-aware client/protocol, should be treated "always" as automatic versioning. </chris> At least for my benefit, could you clarify/restate the problem. We're defining a protocol extension to HTTP for versioning. If a server supports multiple protocols (ftp, gopher, etc) then clearly there will be issues for such servers to maintain data integrity across protocols, but why would it affect DAV? I appreciate it is different for 'down-level' clients (i.e. HTTP without DAV extensions). Tim
