Is there a Web Service Standard (WS*) for Optimistic Locking / Optimistic Concurrency Control (OCC) designed for interoperability?
There are a number of standards related to pessimistic concurrency control mechanisms, such as WS-AtomicTransaction, but as far as I can tell it doesn't provide functionality for version or timestamp handling related to optimistic locking.
I have found one article on the subject Optimistic locking and WCF, but no mayor standard. Are there such or do you know of other samples or patterns that you would like to recommend?
