A Framework for Efficient Discovery of Web Services Across Heterogeneous Registries

Growth and propagation of the Internet has been a contributing factor for information overload which acts as a deterrent for quick and easy discovery of information. As Web services proliferate, the same dilemma perceived in the discovery of Web pages will become tangible. Currently, the automatic discovery of Web services, an important capability of service- oriented architecture (SOA), is mainly achieved by performing inquiries to business registries such as the UDDI or ebXML. The ability to discover Web services across multiple heterogeneous registries is becoming a challenging task and raises several issues such as performance, reliability, and robustness. In this paper, we introduce the Web Service Repository Builder (WRSB) that serves as an integrated SOA registry and repository for managing the proliferation of Web services and system artifacts. Specifically, the proposed framework actively captures and navigates among multiple service registries and provides a unified environment for the discovery of Web services. The WSRB framework is compatible with, and can be integrated seamlessly into, the existing infrastructure without any modifications to the existing environments.
