Abstract
This document describes a Uniform Resource Name (URN) namespace that
is managed by SWIFT for usage within messages standardized by SWIFT.
1. Introduction
SWIFT is an industry-owned cooperative supplying secure, standardised
messaging services and interface software to over 7,500 financial
institutions in 199 countries. The SWIFT community includes banks,
broker/dealers and investment managers, as well as their market
infrastructures in payments, securities, treasury and trade.
The goal of this namespace 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"
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.

RFC 3615 SWIFT URN Namespace September 2003
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.
5. IANA Considerations
The IANA has registered formal URN namespace 15, to SWIFT within the
IANA registry of URN NIDs.
