INSTITUTO DE COMPUTAÇÃO UNIVERSIDADE ESTADUAL DE CAMPINAS A UDDI Extension for Web Service-based Business Process Management Systems

The Universal Description Discovery & Integration (UDDI) is a specification for XML registry that enables functionality-based publication and discovery of Web services. This paper presents a UDDI extension to support Quality of Service (QoS) management in the context of Business Process Management Systems (BPMSs). To allow service selection according to functional and nonfunctional requirements, a BPMS architecture should include brokers to match consumer policies with policies stored in UDDI repositories and monitors to update QoS attributes. The main contributions of this approach are the use of the Web Services Policy Framework specification to describe policies for Web services and a UDDI extension to include QoS attributes.
