Abstract

   The Simple Nomenclator Query Protocol (SNQP) allows a client to
   communicate with a descriptive name service or other relational-style
   query service.  The protocol is useful to services that search many
   data repositories for query responses.  Clients can pose queries on
   relations, list descriptions of relations, and obtain advice on
   reducing the search time and cost of their queries.  Clients are
   informed of the age of information in caches, and may request more
   recent information.  SNQP provides support for graphical user
   interfaces.  It also supports different types of comparison
   operators, so services can use SNQP with a variety of back-end
   servers, e.g. relational database servers, CCSO servers, and servers
   providing relational views of X.500.

   SNQP is an ASCII protocol in the request-reply style of SMTP.  It was
   specifically designed for use with the Nomenclator name and
   information service, and has been useful elsewhere.

1. Introduction

   The Simple Nomenclator Query Protocol (SNQP) is a protocol for
   querying servers that search collections of data repositories.  Users
   retrieve information from an SNQP server by describing attributes of
   the information.  SNQP servers contact one or many data repositories
   to retrieve the response to a user query.  If the data repositories
