3-Level Service Composition and Cashew: A Model for Orchestration and Choreography in Semantic Web Services

Abstract: Abstract. There are two types of behavioural model in the WSMO semantic description of services: an orchestration and a choreography, together called the interface. While an orchestration defines a service's behaviour as a composition of existing parts, a choreography is intended to document the conversation of messages exchanged with a single client. In this paper we present a three-level model for behavioural descriptions, and how the Cashew workflow model fits into this, building on existing work in, and es… Show more

“…Therefore a workflow-based extension to the WSMO specification has been designed and implemented. The extended process model used within Access eGov is based on the workflow CASheW-s model [17]. The state signature is reused from the WSMO specification and replaces the transition rules with the workflow constructs.…”

“…A related approach to process-based Web Service composition is goal-based orchestration [348] using the WSMO conceptual model. The key idea is that each stage in a process can be represented by a WSMO goal rather than a specific service identifier.…”
