    Abstract

    Web services advocate loosely coupled systems, although current applications are limited to centrally controlled structures. The reason for this imitation is the lack of a method for deciding collaboration consistency, that is deadlock freeness and boundedness, in a decentralized way. In particular, an intuitive approach classifies collaborations incorrectly being inconsistent due to the loss of information introduced by the decentralization. In the paper loss of message ordering and message parameter value constraints caused by the decentralization are identified to be the reasons for incorrect decision results. The proposed approach to overcome this issue is to explicate these constraints, which cannot represented in common workflow models.
