Subject: announcing the Knowledge Sharing library on the WWWeb

I am pleased to announce that the knowledge sharing library of the
ARPA Knowledge Sharing Effort is now a World Wide Web site.  The World
Wide Web is rapidly becoming the medium of choice for delivering
information on the internet.  Documents can be brought to your to
your desk from anywhere in the networked world, and presented in
hypertext, graphics, sound, and video.  Increasingly, the web is also
a medium for delivering interactive services, such as database query
services or forms-based interfaces to conventional software.  We have
taken it on as an infrastructure on which to deliver knowledge sharing
technology and products.

The entry point for the knowledge sharing library is:

This is the address (URL) of the root of a large tree of papers,
software, documentation, and other resources.  Of particular interest,
you will find that the library of ontologies have been processed to
to produce hypertext documents that read like polished, on-line
reference manuals.  All uses of a formal term are linked to its
definition; all dependencies and inclusion relationships among
theories are cross-linked as well.  You will also find software (Lisp
and C++) that implements the KQML protocol for agent communication,
and several examples of agents that use the KQML/KIF/ontology
conventions for agent interoperability.  In addition, papers
associated with the Knowledge Sharing Effort are available on-line;
you can browse the abstracts, and retrieve the postscript to your
screen with a click of the mouse.

You are invited to browse the library, and make contributions.  
Send comments, suggestions, additions, etc., to me.

The World Wide Web is simply the union of a huge and rapidly growing
collection of information servers on the internet.  These servers
obey protocols that enable client viewing programs to present the
information on your desktop.  These viewers are high quality, free,
and available on all the many computing platforms (Unix, Mac, PC).

The most popular view is called Mosaic, and is produced by the NCSA.
Here's how to get a Unix/X version.  The Mac and Windows versions are
simple to install.  Here are the directions for ftp'ing and installing
the unix versions.  I got this document on the web at


NCSA Mosaic for the X Window System

Mosaic for X Installation Guide

The NCSA Mosaic anonymous FTP distribution site is;
program files are in directory /Mosaic. 

Executable Binaries

The easiest way to download Mosaic is to retrieve an executable binary from
subdirectory Mosaic-binaries. The following binaries are distributed: 

  Mosaic-sun.Z             Sun 4, SunOS 4.1.x
  Mosaic-sun-lresolv.Z     Sun 4, SunOS 4.1.x, no DNS
  Mosaic-sgi.Z             Silicon Graphics, IRIX 4.x.
  Mosaic-ibm.Z             IBM RS/6000, AIX 3.2.
  Mosaic-dec.Z             DEC MIPS Ultrix.
  Mosaic-alpha.Z           DEC Alpha AXP, OSF/1.
  Mosaic-hp700.Z           HP 9000/700, HP/UX 9.x

To download a binary, put your FTP session into binary mode (type binary), pull
down the file, quit the FTP session, uncompress the binary (type, e.g., 
uncompress Mosaic-sun.Z), make the binary executable (type, e.g., chmod 755
Mosaic-sun), and execute the binary. 

To download a binary from within Mosaic, go to the Mosaic-binaries directory
and turn on Load to Local Disk using the Options menu. Then click on the
appropriate filename, and enter a filename into the Save File dialog box. Turn off
Load to Local Disk. Make the file executable (type, e.g., chmod 755 Mosaic-sun),
and execute the binary. Mosaic should perform the uncompression for you. 

Source Code

The complete Mosaic source code distribution is located in subdirectory 
Mosaic-source. The distribution comes as a single compressed tar file, and can
be compiled on most Unix systems. You must have the X11R4 (or later) and
Motif 1.1 (or later) header files and libraries on your system to compile Mosaic. 

See the README in the source code distribution for more information on
compiling Mosaic. 

Run-time Problems

There are three problems that you may hit when you run a Mosaic binary for
the first time. Click here for more details. 

External Viewers

Mosaic assumes the presence of a number of external viewers -- programs that
Mosaic can use to allow you to view images, movies, PostScript files, etc. that are
retrieved over the network. 

See the subdirectory Mosaic-viewers for copies of the normal source
distributions of some of these viewers. We strongly recommend downloading
and installing these viewers if they do not already exist on your system, as
Mosaic will be much more useful with them present. The Frequently Asked
Questions list also contains a list of hyperlinks to FTP servers where the default
external viewers can be found.
