OK, I was confused and thought an object could serve as it's own lock (Java does something like this). So I need to create a LockItem. Is this class accessible from a DTML Method or should I be looking at an External Method?
An external method. LockItems basically model all of the data required by WebDAV to represent what is expected in a WebDAV "lockdiscovery" property. An object cannot serve as its own lock as there is not a larger locking mechanism in play here - only the WebDAV system. Thus, LockItems are very WebDAV specific - 'exclusive write lock' specific in fact. See also "webdav/davcmds.py", classes Lock and Unlock to see how the locks are created and applied. You might also want to check out the "seatbelt" mechanism in the CMF's Document class as an alternate approach. Jeffrey P Shell, jeffrey@cuemedia.com
