Web Services Atomic Transaction is a web protocol. This page contains links to a formal TLA+ specification of the protocol written in 2003 and to a paper describing that specification. The TLA+ specificaton was based on an informal specification written by F. Cabrera et al. in 2002 that is apparently no longer available on the Web.

Formal Specification of a Web Services Protocol: This is a paper that was presented at the First International Workshop on Web Services and Formal Methods (WS-FM 2004), held February 23-24, 2004 in Pisa, Italy.
