Lessons Learned from Implementing WS-Agreement

WS-Agreement describes a protocol and structure for creating and representing service level agreements. In order to remain domain independent, the authors of the WS-Agreement specification have provided many extension points for domain specific content. This creates high degrees of freedoms for programmers to implement the specification. Many attempts to do this have been made in the past. In this paper, we explain what we have learned from our own and other projects’ attempts of implementing WS-Agreement. The paper presents a set of guidelines how the features of WS-Agreement can be used in a sound way that allows transferring large parts of the WS-Agreement logic into a generic and domain-independent WS-Agreement framework.
