Service-Oriented Computing allows new applications to be developed by using and/or combining services offered by different providers. In several cases a service needs sensitive information from the clients in order to execute. The existence of a trust relationship between the client and the provider determines which restrictions the service has concerning the use of this information by the service. In this paper we present a metamodel for services computing that incorporates the support for trust relationships. The metamodel provides the means for specifying services and service requests including trust requirements and constraints. The proposed metamodel is encompassed in a framework for goal-based service discovery and composition.
