Abstract

   This document describes a URN (Uniform Resource Name) namespace that
   is engineered by the Organization for the Advancement of Structured
   Information Standards (OASIS) for naming persistent resources
   published by OASIS (such as OASIS Standards, XML (Extensible Markup
   Language) Document Type Definitions, XML Schemas, Namespaces,
   Stylesheets, and other documents).

1. Introduction

   The Organization for the Advancement of Structured Information
   Standards (OASIS) produces many kinds of documents: specifications,
   working drafts, technical resolutions, schemas, stylesheets, etc.

   OASIS wishes to provide global, distributed, persistent, location-
   independent names for these resources.

   The Extensible Markup Language (XML) requires that all resources
   provide a system identifier, which must be a URI, in addition to an
   optional public identifier (which provides an alternate mechanism for
   constructing identifiers) and many evolving specifications require
   authors to identify documents by URI alone (XML Namespaces, XML
   Schema, XSLT, etc.).

   Motivated by these observations, OASIS would like to assign URNs to
   some resources in order to retain unique, permanent location-
   independent names for them.

   This namespace specification is for a formal namespace.

   Declaration of structure:

      The Namespace Specific String (NSS) of all URNs assigned by OASIS
      will have the following hierarchical structure:

      There are two branches at the top of the hierarchy: "names" and
      "member".

   The Names Hierarchy

      The NSS in the names hierarchy begins with a document class
      identifier.  There are three classes of identifiers:

      "specification", "tc", and "technical".

      Specifications

         The "specification" hierarchy is for OASIS Specifications.  The
         general structure of the NSS in the specification hierarchy has
         the form:

            urn:oasis:names:specification:{specification-id}
                           :{type}{:subtype}?:{document-id}

Best & Walsh                 Informational                      [Page 2]
RFC 3121               A URN Namespace for OASIS               June 2001

         where "specification-id" is a unique identifier for the
         specification, "type" identifies the document type (document,
         schema, stylesheet, entity, xmlns, etc.), the optional
         "subtype" provides additional information about the document
         type (for example, stylesheet or schema language), and
         "document-id" is a unique identifier for the document.

         The Director of Technical Operations at OASIS assigns document
         types, subtypes, and all unique identifiers.

      Technical Committee Work Products

         The "tc" hierarchy is for work products of OASIS Technical
         Committees.  The general structure of the NSS in the tc
         hierarchy has the form:

            urn:oasis:names:tc:{tc-id}:{type}{:subtype}?:{document-id}

         where "tc-id" is a unique identifier for the Technical
         Committee, and the remaining fields are assigned as per the
         specification hierarchy.

      Technical Papers

         The "technical" hierarchy identifies legacy documents
         (Technical Notes, Resolutions, Memoranda, and Research Papers).
         The general structure of the NSS in the "technical" hierarchies
         has the form:

            urn:oasis:names:technical:{document-type}
                           :{document-id}:{amendment-id}

         The document type is one of the following: "note",
         "resolution", "memorandum", or "researchpaper".

         The document and amendment identifiers are derived from the
