As Richard Fikes pointed out, documents and information can be obtained
via anonymous FTP from under the directory /pub/knowledge-sharing/*.

If, however, what you are seeking is a short overview of the overall effort, the brief
summary below may be of some additional use...

The Knowledge Sharing Effort is a consortium to develop conventions
facilitating sharing and reuse of knowledge bases and knowledge based
systems.  The goal of the effort is to define, develop, and test
infrastructure and supporting technology to enable participants to build
much bigger and more broadly functional systems than could be achieved
working alone.  The output of the effort consists of (1) public-domain
specifications and implementations of supporting technology; (2)
reports, papers, and technical articles; (3) a reusable public library
of proof-of-concept demonstrations.

Building new knowledge-based systems today usually entails constructing
new knowledge bases from scratch.  It could instead be done by
assembling together reusable components.  System developers would then
only need to worry about creating the specialized knowledge and
reasoners new to the specific task of their system.  Their new system
would inter-operate with existing systems, using them to perform some of
its reasoning.  In this way, declarative knowledge, problem solving
techniques and reasoning services could all be shared among systems. 
This would facilitate building bigger and better systems cheaply.  The
infrastructure to support such sharing and reuse would lead to greater
ubiquity of these systems, potentially transforming the knowledge
industry.  Definition of conventions enabling sharing among
collaborators is the essential first step toward these goals.

Technical analyses of knowledge representation technology indicated four
complementary areas in which development of common, agreed-upon
conventions would enhance leverage between individual research efforts. 
(These analyses were initiated in a three-day workshop involving over 40
top AI and database researchers from DARPA, NSF, and industry
communities.)  The Knowledge Sharing Effort is organized around working
groups addressing each of these four areas.  Each working group maintains
an electronic mailing list for discussions.  The groups are:

INTERLINGUA: concerned with translation between different representation
languages, with sub-interests in translation at design time and at
run-time (Working Group Co-Chairs: Richard Fikes and Mike Genesereth.
Mailing-list:  To join, send an e-mail request to

KRSS (Knowledge Representation System Specification): concerned with defining
common constructs within families of representation languages (Working Group
Co-Chairs: Bill Swartout and Peter Patel-Schneider.  Mailing-list:  To join, send an e-mail request to

EXTERNAL INTERFACES: concerned with run-time interactions between
knowledge based systems and other modules in a run-time environment,
with sub-interests in communication protocols for KB-to-KB and for
KB-to-DB (Working Group Co-Chairs: Tim Finin, Jay Weber.  Mailing-list:  To join, send an empty e-mail message to the automated
mailbox and follow the instructions sent in response.)

SHARED, REUSABLE KNOWLEDGE BASES: concerned with facilitating consensus on
contents of sharable knowledge bases, with sub-interests in shared knowledge
for particular topic areas and in topic-independent development
tools/methodologies. (Working Group Co-Chairs: Tom Gruber and Marty Tenenbaum

The Knowledge Sharing Effort currently involves participants from over a
dozen different research centers around the United States, as well as a small
number of centers abroad.  A representative list of participating research
centers includes  AT&T, Carnegie-Mellon University, EITech, Hewlett-Packard
Research Center, Lockheed, Northwestern University, University of
Saarbrucken, USC / Information Sciences Institute, Stanford Research
Institute, Stanford University, Paramax, University of Maryland, University
of Texas, and Xerox Palo Alto Research Center.
