Scope
This standard specifies the application service definition and protocol specification for information retrieval. The service definition part describes the services for searching and retrieving information in databases within an application; the protocol specification part includes the definition of protocol control information, the rules for exchanging this information, and the conformance requirements to be met for implementing the protocol. This standard is applicable to systems supporting information retrieval services, as well as organizations such as information service institutions, universities, libraries, and union cataloging centers.
