WEB SERVICES DISCOVERY

After Web services are created and published in Web services registries such as UDDI or Web Services Inspection Language (WSIL) documents, the service users or consumers need to search Web services manually or automatically. The implementation of UDDI servers and WSIL engines should provide simple search APIs or web-based GUI to help find Web services.

Federated Discovery

However, the current UDDI search mechanism can only focus on a single search criterion, such as business name, business location, business category, or service type by name, business identifier, or discovery URL. In fact, in a business solution, it is very normal to search multiple UDDI registries or WSIL documents and then aggregate the returned result by using filtering and ranking techniques, which are used in Google today. IBM modularized this federated Web services discovery engine in 2001. The released technology from IBM is Business Explorer for Web Services (BE4WS), which was the first released technology to target on federated Web services discovery.
