“…It is worth highlighting the importance of semantics of clauses and validation of the e-contract template. Web services are a major tool to manage the e-contract terms in organizational business systems (Marchione et al, 2009) (Chiu et al, 2003). Regarding the use of contracts in composition of Web Services, a notable work is that one of Milanovic (Milanovic, 2005).…”

Nowadays, most of the approaches for compositions of web services are focused on feasibility of implementation rather than on satisfying business concerns. Meeting business concerns also demands flexible and agile implementations. We present an approach for service composition based on the lifecycle of e-contract. Econtracts have clauses and rules that express business concerns on how services are offered and consumed. We propose an architecture that enables the automation of implementation of composite services. The automation is on the configuration of web service engines. The architectural model supports the publication of contracts that describe how services are offered from different providers in order to develop the composition of services.

The web service technology allows organizations to interact through business processes. However, organizations involved in cooperative business processes have different interests and points of view. A negotiation allows them to discuss their interests and requirements in order to reach an acceptable agreement. We propose an integrated web service negotiation process that takes into account human interaction and the use of different negotiation protocols. It focuses on the application of feature modelling to describe the negotiated services. Our contributions include: (i) the definition of a negotiation process; (ii) the definition of a conceptual model to support the negotiation of web services; (iii) reuse of artefacts generated throughout the negotiation process; (iv) coverage of critical elements in the negotiation of electronic contracts, such as role, properties of electronic services and contract models; and (v) exploration of the process in different application scenarios.
