RFC 3615 SWIFT URN Namespace September 2003 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 [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.
