Proposal for OASIS Extensible Resource Identifier Technical Committee (XRI TC)

Date:      Fri, 06 Dec 2002 10:08:07 -0500
From:      Karl Best <>
Subject:   OASIS TC Call For Participation: XRI TC

A new OASIS technical committee is being formed. The OASIS Extensible Resource Identifier Technical Committee (XRI TC) has been proposed by the following members of OASIS: Geoffrey Strongin, AMD; Krishna Sankar, Cisco; Joseph Moeller, EDS; Jim Schreckengast, Xavier Serret, and Phillipe LeBlanc, Gemplus; Winston Bumpus, Novell; Nat Sakimura, Hiro Ogawa, Tomonori Seki, and Tetsu Watanabe, NRI Pacific; Drummond Reed, Loren West, Dave McAlpin, and Marc LeMaitre, OneName; Dave Wentker, Rajeev Maria, Mike Lindelsee, and Gabe Wachob, Visa International; Michael Willett and Lark Allen, Wave Systems; and Bill Washburn, XNSORG.

The proposal for a new TC meets the requirements of the OASIS TC Process (see, and is appended to this message. The proposal, which includes a statement of purpose, list of deliverables, and proposed schedule, will constitute the TC's charter. The TC Process allows these items to be clarified (revised) by the TC members; such clarifications (revisions), as well as submissions of technology for consideration by the TC and the beginning of technical discussions, may occur no sooner than the TC's first meeting.

To become a member of this new TC you must 1) be an employee of an OASIS member organization or an Individual member of OASIS; 2) notify the TC co-chairs, Drummond Reed ( and Gabe Wachob ( of your intent to participate at least 15 days prior to the first meeting; and 3) attend the first meeting on 9 January. You should also subscribe to the TC's mail list. Note that membership in OASIS TCs is by individual, and not by organization. You must be eligible for participation at the time you time you notify the chair.

The private mail list is for committee discussions. TC members as well as any other interested OASIS members should subscribe to the list by going to the mail list web page at or by sending a message to with the word "subscribe" as the body of the message. (Note that subscribing to the mail list does not make you a member of the TC; to become a member you must contact the TC chair and attend the first meeting as described in the preceeding paragraph.)

A public comment list will be available for the public to make comments on the work of this TC; a message may be sent to the TC via the address

The archives of both of these mail lists are visible to the public at

Proposal: Extensible Resource Identifier (XRI) Technical Committee

Name of TC

Extensible Resource Identifier (XRI) Technical Committee

Statement of Purpose

Increasingly, there is a demand for distributed directory services that enable the identification of resources (including people and organizations) and the sharing of data across domains, enterprises, and applications. There are currently no transport- and application-neutral identification schemes to support this infrastructure.

The purpose of this committee is to define a URI scheme and a corresponding URN namespace that meet these requirements. This TC will also define basic mechanisms for resolving the identifiers in these schemes and for exchanging data associated with these identifiers. This work will enable the creation of Web-like collections of resources (including, but not limited to, data, systems, services, organizations, and people) that extend the WWW's current generalized addressing and linking capabilities.

The URI scheme will conform to RFC 2396. It will also accommodate human-readable names as a subset of the compliant identifiers. The TC will also produce an interoperable URN namespace specification compliant with RFC 2141 and guided by the requirements in RFC 1737 for resources that need the ability to be persistently identified and linked.

The TC will also define an XML schema to associate metadata with resources and a service to manipulate this metadata and data associated with the resources. Specifically, this service will reflect the simple transactional nature of the WWW, i.e., it will use a small set of REST (Representational State Transfer) or CRUD-like operators on an infinitely extensible set of XRI-addressable resources. This data exchange service will provide a platform for integration with directory-related specifications such as LDAP, DSML, and SPML.

This TC's work will be influenced by the general architecture described in XNS and specifically by the XNS Addressing Specification. The XNS specifications published by the XNS Public Trust Organization (XNSORG) will be contributed to the TC for consideration in the committee's work. XNS is licensed under RF terms as described in

List of Deliverables

Delivery schedule to be discussed at the first meeting.

The TC deliverables will include

  1. Use cases & requirements
  2. A syntax specification for the URI scheme & URN namespace
  3. A resolution specification for the URI scheme & URN namespace
  4. An XML schema for associating metadata with identified resources
  5. A REST/CRUD-like data exchange service and bindings for HTTP and SOAP

Relationship to Existing Activities

This TC

  • is defining a URI scheme under RFC 2396 and a URN namespace under RFC 2141 and guided by the requirements in RFC 1737

  • will examine use of the IETF DDDS framework for resolution (RFC 3401-3405)

  • will integrate the W3C XML and XML Schemas architectures for data representation and description

  • will integrate the W3C Web services framework for messaging, service description, and location

  • will integrate the OASIS Web services security framework for secure messaging

  • will examine possibilities for expression and integration of the directory services features with DSML, SPML, UDDI, and ebXML as well as more established directory services specifications such as LDAP



Date and Time of First Meeting

The first meeting will be held by tele-conference on January 9th, 2003 at 2pm Pacific, 3pm Mountain, 4pm Central, 5pm Eastern, 11pm GMT, Friday 7am Toyko.

Meeting Schedule for the First Year

The XRI TC will meet via bi-weekly conference call, on a schedule determined by the TC members. The phone call sponsors will be determined at the initial meeting. Face-to-face meetings will be held as required.

Added Statement

Additional statement from the board of directors of, regarding the intended contribution of technical work to the new TC:

November 27, 2002

Board of Directors, Organization for the Advancement of Structured Information Standards (OASIS)

Dear Sirs,

The XNS Public Trust Organization (XNSORG) recently submitted a charter proposing an OASIS Technical Committee on Extensible Name Service (XNS). In subsequent discussions with OASIS Technical Director Karl Best, several questions were raised regarding the TC charter, work product, and related intellectual property rights (IPR).

With this letter, XNSORG and the sponsors of the TC formally submit a revised TC charter to OASIS, attached, and the board of directors of XNSORG provides to OASIS the following IPR statements regarding this TC charter and work product:

TC Name and Trademark Rights

In this revised charter, the name of the TC is the Extensible Resource Identifier (XRI) Technical Committee. This name was chosen to be generic and XNSORG does not now or in the future intend to assert trademark or other intellectual property rights related to the name "Extensible Resource Identifier" or the abbreviation "XRI". Furthermore XNSORG does not expect or require the term "XNS" to be used in conjunction with the TC or its work product, as this term is currently a trademark of XNSORG.

Specifications to be Contributed

At the first meeting of the TC, XNSORG intends to contribute the then-current version of the XNS Technical Specifications available from the XNSORG website at It is our express intent to contribute these specifications to OASIS under the terms of the OASIS IPR Policy as stated at

XNSORG contributes this work only with the expectation that OASIS will further develop the specifications and XNSORG grants OASIS permission to create derivative works from the specifications. This includes the ability for OASIS to distribute the TCs work product under its own copyright, with attribution for any portions that were originally contributed by XNSORG.

At the time it becomes relevant to the work of the TC, it is also the intent of XNSORG to contribute the then-current version of the XNS Technical Certification Specifications. Note that these specifications are strictly for use in compliance testing and certification by independent certification authorities and XNSORG does not intend or expect OASIS to become a certification authority nor will it be under any obligation whatsoever related to compliance or certification activities.

Relevant Intellectual Property Rights

To the best of our knowledge, the only intellectual property rights necessary to practice the XNS Technical Specifications or XNS Technical Certification Specifications are those conveyed in the attached XNS License under Definition 22, "Patent Rights". All such rights are currently under the exclusive authority of XNSORG as per the IPR Agreement between OneName and XNSORG available on the XNSORG website at

The board of directors and counsel of XNSORG believe that the terms of the XNS License fully comply with the terms of the OASIS IPR Policy, specifically section OASIS.IPR.3.2.C. Note that section 8 of the XNS License, Sublicensing, has been revised in v1.1 to permit sublicensing under the same terms as the original license.

Relationship of XNSORG to OASIS

XNSORG is currently a member of OASIS. Subsequent to the contribution of the specification, XNSORG will participate as an equal member of the TC with other OASIS members and expects no special rights or privileges. XNSORG will continue as an independent non-profit organization to perform its other chartered functions to promote and advance technology and infrastructure based on the specifications. In this endeavor, XNSORG will be a consumer of the work product of the TC.

In conclusion, since XNSORG is required by the XNS IPR Agreement to manage XNS as an Open Standard as defined in Definition 18 of the XNS License, it is the sincere hope of XNSORG that this contribution complies with both the letter and the spirit of the OASIS IPR Policy. Should there be any additional questions, please contact the undersigned and we will work to answer them as quickly as possible.

XNSORG looks forward to a long and fruitful relationship with OASIS in our mutual work to advance standards for intelligent information interchange.


Bill Washburn, XNSORG President and Managing Director
W. Scott Blackmer, XNSORG General Counsel
Adam Engst, XNSORG Chairman
