On The Extension and Integration of Existing SAP Enterprise Services in The Context of SOA4All

The SOA4All project aims to provide an user-friendly service delivery platform to a wide range of users consisting of both experts and laymen. This novel platform uses semantic web technology to annotate syntactic based web services and use logical reasoning to discover and mediate a large number of services for easier consumption and efficient delivery to end users. At SAP Research, the integration of existing, currently non-semantic SAP enterprise services into the SOA4All framework is studied. In order to obtain a set of synthesized complex functionalities for a process scenario of business registration at governmental administration which is supported by automated ERP systems using existing enterprise services, we show that using a well-known and proven approach of dynamical basic action theory in the situation calculus to axiomatize the domain can soundly and correctly capture the interaction dynamics, invocation constraints of the component enterprise services so that the constraints and requirements for integration are satisfied. With an in-depth survey of a series of semantic service matching and automatic service composition approaches in the industry and academia, we provide a consolidated, critical view of contemporary intelligent agent based solutions to the service composition problem in the domain of knowledge representation and artificial intelligence. We argue that it can suitably solve the challenging integration problem of existing enterprise services.
