Subject: [tm-pubsubj-comment] RE: Request membership in (XRI TC)

Mary, Gabe

Smart move from you both :)

I think we should think about a formal liaison between xri and Pubsubj
I guess Mary volunteers for that ;-)

Hi Gabe,

I have been seeing you on the #topicmaps@ irc.openprojects.net  for some

days now and wondered who you were :)

For this committee your objective to "...define a URI scheme and a 
corresponding URN namespace for distributed directory services that
the identification of resources (including people and organizations) and

the sharing of data across domains, enterprises, and applications"  has 
some overlap with what we have been looking into the past year in the TM

Published Subjects TC which you seem to be aware of.

Of course there are differences in the approach, but it is good to take
look at these differences. You also mentioned working with LDAP metadata

which is of interest to me too.

If you take a look at the recent paper that I presented at Extreme
Languages 2002, you will have some idea of what I and the committee has 
been working on and where there is some overlap between these
committees, I 


The standards work that I have planned for 2003 is to work on  Published

Subjects for Geography and Languages (OASIS GeoLang Committee) and
and comment on the SC34 WG3 standards for Topic Maps for Japan, and 
finalize the drafts of the Topic Maps Published subjects Requirements

As you can see, I am very busy, but I will subscribe to the lists to
what your group is doing and anyone here is welcome to stop by the

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 http://oasis-open.org/committees/process.shtml), 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 (drummond.reed@onename.com) and Gabe
Wachob (gwachob@visa.com) 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

The private mail list xri@lists.oasis-open.org 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
http://lists.oasis-open.org/ob/adm.pl, or by sending a message to
xri-request@lists.oasis-open.org 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

(i) Name of TC:

Extensible Resource Identifier (XRI) Technical Committee

(ii) 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fs
XNS is licensed under RF terms as described in

(iii) 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

- 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

- 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.
