                draft-ietf-mile-enum-reference-format-04

Abstract

   The Incident Object Description Exchange Format [IODEF] provides a
   Reference class used to reference external entities (such as
   enumeration identifiers).  However, the method of external entity
   identification has been left unstructured.  This document describes a
   method to provide structure for referencing external entities for the
   [IODEF] Reference class.

INTERNET DRAFT     IODEF Enumeration Reference Format        May 7, 2014

1  Introduction

   There is an identified need to specify a format to include relevant
   enumeration values in an IODEF document.  It is anticipated that this
   requirement will exist in other standardization efforts within
   several IETF Working Groups, but the scope of this document pertains
   solely to [IODEF].

1.1  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].

2.  Referencing External Enumerations

   The need is to place enumeration identifiers and their references in
   [IODEF]'s Reference class.  There are several ways to accomplish this
   goal, but the most appropriate at this point is to require a specific
   format for the ReferenceName string of the [IODEF] Reference class,
   and use an IANA registry to manage the resulting reference formats.

      +------------------+
      | Reference        |
      +------------------+
      |                  |<>----------[ ReferenceName ]
      |                  |<>--{0..*}--[ URL           ]
      |                  |<>--{0..*}--[ Description   ]
      +------------------+

                   FIGURE 1: [IODEF] Reference Class 

   Per [IODEF] the ReferenceName is of type ML_STRING.  This becomes
   problematic when specific references, especially enumerations such as
   [CVE], [CCE], [CPE] and so on, are referenced - how is an implementer
