Overview: In a lookup service, servers can bind a (symbolic) name and/or a set of properties to distributed objects or other distributed resources. The lookup service can lookup these objects by name or by property. Usually it provides the location of the service and other information how to access the service, such as the remote interface or protocols supported. Clients need not know the location of servers but only the location of the lookup service - which can be provided by bootstrapping mechanisms, such as initial references or broadcast messages. All other required location information is retrieved via the lookup service.
