Abstract: 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 add extra-functional properties to modelled services. In this regard, we propose the use of UML for modelling services based on a component representation, in order to provide a model environment in which extra-functional properties are added, also using UML. The implemented models will be independent of a final implementation language or platform, thus making it necessary to specify a particular type of model into which to convert the independent one in a subsequent step. In order to meet this requirement a Jax-rpc-based meta-model is proposed for services and a soap tag, aspect- and policy-based ones for properties. The use of aspect-oriented techniques also at code level provides great system modularity and perfect traceability along the model-driven process.
