One embodiment relates to a system for linking together multiple registries and aggregating data from the multiple registries. The system includes a plurality of local resource or service (resource/service) registries, a distributed index storage and retrieval system, and at least one proxy registry. The proxy registry is configured to receive a search query from a client system, retrieve information from the distributed index storage and retrieval system as to which of the local resource/service registries are relevant to the search query, and obtain pertinent entries from said relevant resource/service registries. Other embodiments are also disclosed.
