                   Object Identifier Registry for the
      Long-Term Archive and Notary Services (LTANS) Working Group

Abstract

   When the Long-Term Archive and Notary Services (LTANS) working group
   was chartered, an object identifier arc was set aside for use by that
   working group.  This document describes the object identifiers that
   were assigned, and it establishes IANA allocation policies for any
   future assignments within that arc.

1.  Introduction

   When the Long-Term Archive and Notary Services (LTANS) working group
   was chartered, an object identifier arc was set aside for use by that
   working group.  These object identifiers are primarily used with
   Abstract Syntax Notation One (ASN.1) [ASN1-88] [ASN1-97].

   The LTANS object identifier arc is:

      id-ltans OBJECT IDENTIFIER ::= { iso(1) identified-organization(3)
                                       dod(6) internet(1) security(5)
                                       mechanisms(5) ltans(11) }

   This document describes the object identifiers that were assigned,
   and it establishes IANA allocation policies for any future
   assignments within that arc.

2.  Subordinate Object Identifier Arcs

   Three subordinate object identifier arcs were used.  The first arc,
   id-mod, was used to assign ASN.1 module identifiers.  The second arc,
   id-ct, was used to assign Cryptographic Message Syntax (CMS) content
   types.  The third arc, id-em, was set aside for Evidence Record
   Syntax (ERS) encryption methods.

      id-mod  OBJECT IDENTIFIER ::= { id-ltans 0 }
      id-ct   OBJECT IDENTIFIER ::= { id-ltans 1 }
      id-em   OBJECT IDENTIFIER ::= { id-ltans 2 }

3.  Module Identifiers

   The Evidence Record Syntax (ERS) [RFC4998] includes two ASN.1
   modules.  Both modules define the same syntax, but one module uses
   the 1997 ASN.1 syntax, and the other module uses the 1988 ASN.1
