The recent development in cloud computing and Web service delivery encouraged companies from different disciplines to offer their services to customers over the Internet. Since different domains use different language of encounter to establish their contracts, a generic negotiation framework that can be tailored to a specific domain is needed. In this paper, we will present a generic domain-independent marketplace architecture that allows user agents to interact with service providers using two simple and yet powerful negotiation protocols. Service providers have different capabilities depending on the domain of interest. Hence, a dynamic message structuring capability is needed. A key solution to support expressive power is to design an ontology that contains specializations between different domains. The Integration of the domain-dependent ontology with the domain-independent marketplace gives the designer a powerful tool in which systems can be tailored based on the operational purpose. We demonstrate a proof of the concept by implementing the negotiation framework using Discrete Event Specification/Service Oriented Architecture (DEVS/SOA) environment.
