UDDI (Universal Description, Discovery, and Integration) plays the pivotal role of matchmaking between service provider and service requester. Sophisticated publish and inquiry capabilities allow providers to describe their offerings, and seekers to locate them. The quality and depth of a service description is critical to how easily that service can be found by interested parties. Likewise, result sets from find operations can be unmanageable if search criteria are imprecise. Services can be described in UDDI in terms of contact information (White Pages), classification (Yellow Pages), and invocation details (Green Pages). Support for taxonomic classification of all entities in UDDI helps users find and register Web services in a standard way. Default taxonomies such as NAICS, UNSPSC, and ISO 3166 in UDDI v2-compliant registries enable classifications in broad ter... (more)

UDDI and User-Defined Taxonomies

UDDI allows providers to publish information about their services in a common registry. A key part of this process is to describe services in an accurate and consistent way so potential users can easily find them using UDDI inquiry functions. Classifying services with user-defined taxonomies is an effective way to improve search results. Part 1 of this series, "Create and Test a User-Defined Taxonomy in WebSphere Studio" [WJ, Vol. 3, issue 1], described how you can define and test taxonomies for UDDI in IBM WebSphere Studio's Unit Test environment. This article explains how to d... (more)
