A Server Side SOA Meta Model for Assigning Aspect Services

Abstract. Service oriented architectures allow heterogeneity in general and hence support the integration of legacy systems. But legacy systems must often be handled as black boxes and they usually lack additional requirements for new environments. The most important is security. Wrapping services and integrating them via enterprise service buses is one way to tackle this problem but it brings about proprietary and heavy weight software suites. Therefore, a lightweight design concept is missing which fosters encapsulating services at a platform independent level. Below, we present how aspect services can be assigned to services and underline how our concept becomes handy during design time. Additionally, we discuss tool support for assigning aspect services to services.
