1.  Introduction

   The Consultative Committee for Space Data Systems (CCSDS) [CCSDS] was
   formed in 1982 by the major space agencies of the world to provide a
   forum for discussion of common problems in the development and
   operation of space data systems.  At the time of publication of this
   document, it is composed of eleven member agencies, twenty-eight
   observer agencies, and over 100 industrial associates.  Since its
   establishment, CCSDS has been actively developing recommendations for
   data- and information-systems standards, intended to promote
   interoperability and cross support among cooperating space agencies.
