Implementing Non-Functional Service Descriptions in SOA

Stephan Aier, Philipp Offermann, Marten Schoenherr & Christian Schroepfer

This article describes a framework for extended service descriptions based on OWL-S (Web Ontology Language for Services) focusing on non-functional criteria. Necessary service management tasks will be introduced and extended by corresponding data elements and statements for its automated support. After a short comparative description of several existing approaches to semantic service descriptions the paper addresses the actual extension of OWL-S. Non-functional extensions as service lifecycle elements and Quality of Services (QoS) are added. To extend QoS capabilities, the approach combines the common extension mechanism with UML (Unified Modeling Language) Profile for QoS. A prototype delivers the proof-of-concept for the first part of the extension. The prototype implements SOA-specific authentications and all basic features for a tool-supported service management using extended semantic service descriptions by defining an ontology-based service taxonomy and service annotation.
