In my experience, the semantics of "versioning" are so tightly bound to particular applications that it's really hard to find common threads.  You saw that happen here when we were arguing about atom:updated, Asbjørn had a particular vision of versions that seemed obvious to him and unreasonable to others.  When a textbook publisher and a medical-instrument embedded-software maker and a wiki implementor use the word "version", I guarantee you they mean entirely different and wildly incompatible things. Good luck; you'll need it. -Tim I concur with the word of warning (which shouldn't be construed as anything more than an individual offering up their experience for what that's worth).  Check out RFC3253, DeltaV -- in order to get anything published, it had to have a ton of optional features which makes it difficult to write general DeltaV clients that interoperate against multiple servers.  I haven't heard of any such clients yet!
