The NASA/Science Office of Standards and Technology (NOST) has taken the lead in an ISO/Consultative Committee for Space Data Systems (CCSDS) effort addressing standards for archives and in organizing U.S. participation. The initial task is to develop an archiving reference model to establish common concepts and terminology across disciplines ranging well beyond space-related data. A very well attended and productive U.S. workshop was held October 11-12, 1995, at the University of Maryland during which the draft reference model concepts were validated and extended. These were presented at the first CCSDS archiving session, held at the Rutherford Appleton Laboratory in Didcot, United Kingdom, on October 26-27, 1995, and they were enthusiastically accepted. This process is scheduled to reach a draft international standard (DIS) reference model in May 1998. NOST encourages participation by all interested parties and invites those parties to register their interests and obtain additional information from the U.S. Archiving Standards Web pages at URL http://bolero.gsfc.nasa.gov/nost/isoas/us/overview.html or by sending E-mail to Don Sawyer at firstname.lastname@example.org.
