ANSI/NISO Z39.50-2003 (S2014) Information Retrieval: Application Service Definition & Protocol Specification


This standard defines a client/server based service and protocol for Information Retrieval. It specifies procedures and formats for a client to search a database provided by a server, retrieve database records, and perform related information retrieval functions. The protocol addresses communication between information retrieval applications at the the client and server; it does not address interaction between the client and the end-user.
