 Abstract

   This document describes a Uniform Resource Name (URN) namespace that
   is managed by SWIFT s.c.r.l. (societe cooperative a responsabilites
   limitees) for usage within messages standardized by SWIFT.

1. Introduction

   SWIFT is an industry owned cooperative supplying secure messaging
   services and interface software to over 7,000 financial institutions
   in 196 countries.

   The goal of this name space is to ensure the stability and
   uniqueness of the names of various items that are used within the
   messages exchanged between financial institutions. SWIFT is
   one of the principal standardization bodies for financial messages
   and services. This standardization process identifies the structure
   and meaning of messages exchanged for various financial services

   offered by financial institutions. It is essential that names of
   items (such as the XML schema describing the message itself) can be
   used to identify the resource even years after the message has been
   exchanged.
   The same resource may exist in multiple physical locations, and
   thus multiple URL's but only a single URN.


2. Specification Template

   Namespace ID:

      "swift" requested.

   Registration Information:

      Version 1
      Date: 2001-08-01

   Declared registrant of the namespace:

      SWIFT s.c.r.l.
          Avenue Adele 1
          B-1310 La Hulpe
          Belgium

   Declaration of syntactic structures:

      The structure of the Namespace Specific String is a flat space
      <URN chars> [1] which have no knowable structure outside of the
      context of the SWIFT community internal resolver. Future changes
      to the assignment methods may allow others to assign sub-spaces
      of the flat namespace but again, this knowledge is only valid
      internally and should never be inferred or relied upon
      externally.

   Relevant ancillary Documentation:

      None

   Identifier uniqueness considerations:

      Identifiers are assigned by SWIFT URN Registration that
      guarantees uniqueness. This is simply achieved by keeping track
      of already assigned names and comparing all new proposed names to
      the database ones. If the name already exists a new one has to be
      proposed.

   Identifiers persistence considerations:

      The assignment process guarantees that names are not reassigned.
          In any case swift URNs are guaranteed to remain valid for 15
          years.

draft-swift-urn-id.txt      SWIFT URN Namespace            December 2001

Process of identifiers assignment:

        Names are granted via SWIFT proprietary registration procedures.

   Process for identifier resolution:

      swift URNs are resolved via URN resolvers run under SWIFT
          responsibility.

   Rules for lexical equivalence:

      No special consideration.

   Conformance with URN syntax:

      No special consideration.

   Validation mechanism:

      None specified.

   Scope:

      This namespace is reserved to the global financial community.

3. Examples

   The following examples are not guaranteed to be real.  They are
   listed for pedagogical reasons only.

      urn:swift:xsd:epp$mi.i-2.0
      urn:swift:type:fin$103


4. Security Considerations

   Since the URNs in this namespace are opaque there are no additional
   security considerations other than those normally associated with
   the use and resolution of URNs in general.

   It is noted however that attempting to resolve a swift URN through a
   resolver other than the one provided by SWIFT is error
   prone. In any case it is not considered authoritative.
