A URN Namespace for Public Identifiers

Abstract

This document describes a URN (Uniform Resource Name) namespace that is designed to allow Public Identifiers to be expressed in URI (Uniform Resource Identifiers) syntax.

The IETF XML Registry

“…In practice, PUBLIC identifiers are typically Formal Public Identifiers [ISO.8879.1986] but they are not restricted to just that set. As said in [RFC3151]:…”

“…In the case where the registrant does not provide one, the IANA will assign one of the form 'urn:ietf:params:xml:pi:<id>'. Registrants are encouraged to investigate RFC 3151 [RFC3151] as a recommended method for minting a URN that can also be represented as an FPI.…”

A Uniform Resource Name (URN) Namespace for the International Organization for Standardization (ISO)

“…o The OID scheme, documented in [RFC3061] o The PublicId scheme, documented in [RFC3151] The OID scheme is derived from the joint ISO/ITU- :1987]. This standard assigned the registry authority for all identifiers in the { iso(1) } namespace to ISO, and therefore, ISO controls the registry of all identifiers beginning "oid:1:".…”
