+
+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.

+
+
+ 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.
