【 摘 要 】

In order to tackle the entire web service life cycle, it is necessary to face how to model systems based on service functionality and also how to addextra-functional properties to modelled services. In this regard, we propose firstof all to use UML for modelling services based on the Service ComponentArchitecture (SCA) specification, in order to provide a model environment inwhich extra-functional properties are added, also using UML. The implementedmodels based on these profiles will be independent of a final implementationlanguage or platform, thus it is necessary to specify a particular type of modelinto which to convert the independent one in a subsequent step. In order to meetthis requirement a JAX-RPC based specific metamodel is proposed for servicesand a soap tag, an aspect and a policy based ones are proposed as theintermediate step between the independent model and the final code.
