Abstract: Improvements are provided in a service registry in SOA and in service propagation, query, and service selection and routing methods during service invocation. The service registry is connected with a local service domain and a remote service registry and comprises: a local service information manager for registering local services in the local service domain; and a local service information repository connected with the local service information manager for storing service metadata of the local services. The service registry further comprises: a remote service information manager connected with the local service information manager and the remote service registry for receiving a remote service index from the remote service registry; and a remote service information repository connected to the remote service information manager for storing the remote service index received from the remote service registry. The service registry makes it easy to realize service control and share among different service registries.
