Subject: OASIS URN specification


Attached is a proposed submission for an OASIS URN namespace. This was
written by Norm Walsh at the request of Jon Bosak to fill the need we have
for a registered namespace for OASIS documents, including current TC
specifications and other work products, historical technical work products,
XML.org submissions, etc.

I am sending this to OASIS TC chairs and the members of ACXO as this applies
to the work of these committees. I would like to be able to submit this to
the OASIS board for consideration at our board meeting at the end of this
week; in order to do so I would need to get your feedback in the next couple
of days. After approval by the board it can be submitted to the IETF.

Abstract

   This document describes a URN 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 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.

Internet-Draft         A URN Namespace for OASIS           December 2000


   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. 

2. Specification Template

   Namespace ID: 

     "oasis" requested.

   Registration Information: 

     Registration Version Number: 1
     Registration Date: 2000-12-15

   Declared registrant of the namespace: 

     OASIS
     Karl Best

   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 four classes of identifiers:
       "specification", "tc", "xmlorg", and "technical". 

       Specifications 

         The "specification" hierarchy is for OASIS Specifications. The

Internet-Draft         A URN Namespace for OASIS           December 2000


         general structure of the NSS in the specification hierarchy
         has the form: 

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

         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. 

       XML.org 

         The "xmlorg" hierarchy is for documents placed in the XML.org
         repository. The general structure of the NSS in the "xmlorg"
         hierarchy has the form: 

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

         and is constructed 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",

Internet-Draft         A URN Namespace for OASIS           December 2000


         "resolution", "memorandum", or "researchpaper". 

         The document and amendment identifiers are derived from the
         legacy system for naming these documents. The document
         identifier consists of a two digit year and a sequential
         number, the amendment identifier is the year of the amendment. 

     The Members Hierarchy 

         The NSS in the members hiearchy begins with a unique member
         identifier assigned by OASIS. The string following the member
         identifier is opaque. For example: 

         urn:oasis:member:A00024:x 

         The member identifiers will be assigned by The Director of
         Technical Operations at OASIS. The opaque string is defined by
         the owner of the branch that begins with
         "urn:oasis:member:{member-id}:". 

   Relevant ancillary documentation: 

         None

   Identifier uniqueness considerations: 

         Identifier uniqueness will be enforced by the Director of
         Technical Operations who assigns unique identifiers to all
         documents identified by URN.

   Identifier persistence considerations: 

         OASIS is committed to maintaining the accessability and
         persistence of all the resources that are assigned URNs.

   Process of identifier assignment: 

         Assignment is limited to the owner and those authorities that
         are specifically designated by the owner. OASIS will assign
         portions of its namespace (specifically, those under the
         members hierarchy) for assignment by other parties.

   Process of identifier resolution: 

         The owner will distribute catalogs (OASIS TR9401 Catalogs)
         that map the assigned URNs to resource identifiers (e.g.,
         URLs). In addition, the owner may provide an online resolution
         service based on RFC2483.
         The owner will authorize additional resolution services as

         appropriate.

   Rules for Lexical Equivalence: 

         URNs are lexically equivalent if they are lexically identical.

   Conformance with URN Syntax: 

         No special considerations.

   Validation mechanism: 

         None specified. The owner will publish OASIS TR9401 Catalogs.
         The presence of a URN in a catalog indicates that it is valid. 

   Scope: 

         Global


3. Examples

4. Security Considerations

   There are no additional security considerations other than those
   normally associated with the use and resolution of URNs in general.
