The engineering of a service-oriented system requires the specication of functions that Web Services (WSs) should provide, before wss are built or selected. Written in a service description language, the service specication instantiates concepts dierent than those used for Requirement Engineering (RE): the former speaks in terms of operations, metrics and bindings, while the latter manipulates, goals, evaluations and domain assumptions. It is, however, clear that functions expected of WSs to select or build will be relevant to the stakeholders if they satisfy the stakeholders' requirements. As a result, there is a gap between the two specications which must be bridged in order to ensure that the WS system is adequate w.r.t. requirements. This paper proposes mappings between the concepts of requirements ontology and those of service taxonomy induced by the WSDL and the WSLA languages. A working prototype is presented that implements the mappings and is used to translate the instances of RE concepts into instances of WSDL and WSLA concepts. The mappings and the prototype facilitate the engineering of ws systems, as fragments of WS descriptions can be generated from requirements as a rst specication of a service request.
