XML-Based Advanced UDDI Search Mechanism for B2B Integration

摘要

Exploring appropriate business applications published as Web Services in UDDI registries is a critical issue. Search for such applications should be effective in terms of time and uniformed in terms of interfaces. In this paper, an XML-based advanced UDDI exploring engine, Business Explorer for Web Services (BE4WS), that provides developers with standard interfaces for efficiently searching business and service information in single or multiple UDDI registries is presented. The engine processes the proposed UDDI Search Markup Language (USML) that specifies a search request comprising multiple queries, UDDI sources, search criteria, and aggregation operator. The core component of BE4WS, Advanced UDDI Search Engine (AUSE), aggregates search results from different UDDI registries based on the USML request and built-in intelligent search facilities with the ability to cross-reference multiple categories. An aggregation example using BE4WS is demonstrated to enable easy B2B integration.
