Aspect-Oriented Techniques for Web Services: a Model-Driven Approach

Abstract

Web Service technologies offer a successful way for interoperability among applications,
but 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 first of all a versatile and simple UML
profile based on the Service Component Architecture specification for modelling services,
in order to provide a model environment in which to add extra-functional properties.
Secondly, a new UML profile is proposed to model and reuse the said extra-functional
properties in service models. The implemented models based on these profiles will be
independent from a final implementation language or platform, thus it is necessary to
specify a particular type of model to convert the independent one into in a subsequent step.
In order to meet this requirement an object, an aspect and a policy based models are
proposed as the intermediate step between the independent model and the final code. We
acknowledge that there are tools available which convert Java models into web services' Java
code, and it is not our aim to build a tool to fulfil this requirement. Regarding
extra-functional properties, aspect-oriented techniques allow them to be easily modularized
and reused; in this respect, properties are implemented as aspects in a totally transparent
way and avoid the need to modify service code in an intrusive manner on adding extra-functional
properties, improving our system maintenance. Furthermore, this way traceability between the
model and the code is perfectly maintained in both directions.
