Abstract

   This document describes a Uniform Resource Name (URN) namespace for
   the Society of Motion Picture and Television Engineers (SMPTE) for
   naming persistent resources that SMPTE produces or manages.  A
   subnamespace for Universal Labels is specifically described.

1.  Introduction

   SMPTE (the Society of Motion Picture and Television Engineers) is an
   internationally-recognized standards-developing organization.
   Headquartered and incorporated in the United States of America, SMPTE
   has members in over 80 countries on six continents.  SMPTE's
   Engineering Documents, including Standards, Recommended Practices,
   and Engineering Guidelines, are prepared by SMPTE's Technology
   Committees.  Participation in these Committees is open to all with a
   bona fide interest in a committee's work.  SMPTE cooperates closely
   with other standards-developing organizations, including ISO, the
   IEC, and the ITU.  Also, the SMPTE Registration Authority maintains a
   registry of Universal Labels (ULs) used in identifying the type and
   encoding of data within data streams associated with audio-visual
   material.

   SMPTE would like to assign unique, permanent, and location-
   independent names using URNs for resources that SMPTE produces or
   manages.

   This namespace specification is for a formal namespace.

2.  URN Namespace Definition Template

   The following template is provided in accordance with [RFC3406].

      Namespace ID:

         smpte

      Registration Information:

         Version: 2

         Date: 2007-07-08

      Declared registrant of the namespace:

         Registering Organization: Society of Motion Picture and
                                   Television Engineers

RFC 5119                  SMPTE URN Definition             February 2008

      Declaration of structure:

         The Namespace Specific String (NSS) of all URNs that use the
         "smpte" NID shall be conformant to the URN syntax requirements
         defined in [RFC2141].

         URNs for the "urn:smpte" namespace shall follow the structure
         defined in [SMPTE2029].

         SMPTE (or it successor) may add additional subnamespaces
         in the future.  Any system that deals with URNs for the
         "urn:smpte" namespace should be written with the awareness
         that this could occur at any time.

         For informative purposes, the identifier structure described
         using ABNF (according to [RFC4234]) is as follows:

            ;start ABNF notation

            URN = "urn:" NID NSS

            NID = "smpte:"

            NSS = UL-NSS / other-NSS

            UL-NSS = "ul:" UL

            UL = QUADBYTE *(DOT QUADBYTE)

            DOT = %x2E ; period

            QUADBYTE = 4BYTE

            BYTE = 2HEXDIG

            other-NSS = 1*(DIGIT / ALPHA / "-"/":")

            ; other-NSS that conforms with [RFC2141] for future
            expansion
