An apparatus and method is provided to dynamically search for available Web services by persistently searching a distributed multi-level UDDI registry chain, interrogating their published technical specifications and enabling the consumer to find, bind, and invoke the desired Web service in real-time and without intervention by the consumer. The search criteria includes identifying candidate published services that fall within an acceptable margin of error based on information previously published within a consumer service profile. The measure of conformance between the registry semantic map and consumer service profile is parameterized and chosen by the consumer in advance. The service profile includes an XML schema which exposes consumer profile metadata and corresponding information sets used by a rules engine for pattern matching purposes.

A method (and structure) of querying one or more Web-based data sources, includes receiving a compound query statement having at least one first-level query and at least one aggregation operator.

A uniform approach for web service discovery is provided through common auto-discovery logic for cloud-based or enterprise-based deployments for a specific web service. Appropriate credentials may be applied employing a uniform method using an appropriate authentication scheme for on-premise, fully hosted, or partially hosted auto-discovered web services. A common interface may be implemented even if the protocols for discovery differ from service to service or between cloud-based deployment and enterprise-based deployment for the same service. Web service locations auto-discovered through different protocols may be cached for subsequent use.
