               A MIB Textual Convention for Language Tags

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This MIB module defines a textual convention to represent BCP 47
   language tags.  The intent is that this textual convention will be
   imported and used in MIB modules that would otherwise define their
   own representation.

RFC 5131                     LANGTAG TC MIB                December 2007

1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   It defines a textual convention to represent BCP 47 [RFC4646]
   language tags.

   The LangTag TEXTUAL-CONVENTION defined by this RFC replaces the
   similar LanguageTag TEXTUAL-CONVENTION defined by RFC 2932 [RFC2932].

   The old LanguageTag TEXTUAL-CONVENTION is used by some existing MIB
   modules.  New MIB modules should use the LangTag TEXTUAL-CONVENTION,
   which has been created (and is to be preferred) for the following
   reasons:

   o  Its syntax description is current, and is more comprehensive.

   o  It is short enough to use as an index object without subtyping,
      yet is of adequate length to represent any language tag in
      practice.

   o  It is provided in a dedicated MIB module to simplify module
      dependencies.

   It is not possible to apply changes in syntax and length to an
   existing textual convention.  This is why the creation of a new
   textual convention with a new name was necessary.

2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

3.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].
