Integrating Semantic Web Services and Matchmaking into ebXML Registry

In: Proceedings of the Fourth International Workshop SMR2 2010 on Service Matchmaking and Resource Retrieval in the Semantic Web; Shanghai, China

Category: Proceedings

Abstract

While the "Universal Description, Discovery and Integration" (UDDI) service registry standard has drawn great attention by the research community, it has not been widely adopted by the software industry. Objections towards UDDI include technical as well as conceptional arguments. Being an official ISO standard and providing a number of features UDDI is missing, "Electronic Business using Extensible Markup Language" (ebXML) Registry could be an adequate alternative for the implementation of service registries and/or repositories. However, little work has been done regarding the integration of Semantic Web Services (SWS) into ebXML Registry. In this paper, we present a solution extending the ebXML Registry by capabilities to handle and provide SWS. This includes a concept for the integration of SWS into ebXML Registry as well as a prototypical implementation using SAWSDL and the open source framework freebXML.

Query Languages for Semantic Web Services

In: Service Science - Neue Perspektiven für die Informatik - Proceedings der Informatik 2010, Lecture Notes in Informatics; Leipzig

Category: Proceedings [Find it]

Abstract

Even though service discovery is one of the vital steps in Web service invocation, service requests are usually expressed by rather simple means. While syntax-based service descriptions are usually addressed using keyword-based queries, Semantic Web Services are queried using ``perfect'' service descriptions. Hence, a service requester is not able to control the outcome of the discovery process in-depth by specifying similarity ranges or to explicitly state which syntax- and semantic-based parts of a service description should be addressed. In this paper, we present an analysis of current approaches to service request formulation and identify requirements a query formalism for Semantic Web Services should fulfill. Furthermore, we give a brief preview on SWS2QL, a SPARQL-based query language for Semantic Web Services.

On distributed SLA monitoring and enforcement in service-oriented systems

In: International Journal On Advances in Systems and Measurements, Vol. 2, No. 1

Category: Publications in scientific journals

Abstract

For the integration of systems across enterprise boundaries, the application of Web service technology and the Service-oriented Architecture (SOA) paradigm have become state of the art. Here, the management of the quality delivered by third party services is crucial. In order to achieve high service quality, requirements therefore need to be initially specified using Service Level Agreements (SLAs), which are later on monitored during runtime. In case of SLA violations, appropriate countermeasures have to be executed. The paper presents an integrated approach for SLA monitoring and enforcement using distributed autonomous monitoring units. Additionally, the paper presents strategies to distribute those units in an existing service-oriented infrastructure based on mixed integer programming techniques. Furthermore, appropriate framework support is given by the AMAS.KOM framework enabling distributed SLA monitoring and enforcement based on the developed distribution strategies. As a foundation for our approach, the WS-Re2Policy language is presented, which allows the specification of both requirements with respect to service quality and the necessary countermeasures at the same time.
