Abstract

This paper presents a high-level, visual Service Creation Environment (SCE) for web services. The SCE introduces two main concepts: services and composition templates. Composition templates are abstract descriptions of reusable compositions containing several placeholders for services. Services are verified to be compatible with the composition template when a service is mapped onto a composition template. The SCE supports the modularization of crosscutting concerns using both the general-purpose AOP language Padus and several concern-specific languages. Aspects can be visually deployed on a target composition template or service, which automatically triggers the weaving process.
