Enriching UDDI Information Model with an Integrated Service Profile

Service discovery is one key aspect in the enabling technologies for service-oriented systems including Web Services. Growing attention has been paid to the content of business and service descriptions to allow services to be discovered more flexibly and accurately. This paper presents an information model called an integrated service profile that covers aspects of Web Services, i.e. attribute-based profile and specification-based profiles. Attribute-based profile contains attributes that are described more easily with some values, while specification-based profiles represent attributes whose values are complex and then should be described as specifications. The specifications could describe Web Services in terms of their semantic structure, behaviour and rules, and composition. The paper proposes to represent these specifications by an ontology language, and hence they can be used further to discover Web Services semantically.
