Essence is a resource discovery system based on semantic file indexing.
It's written in Perl and C and has been tested on SunOS 4.x systems.
The Essence prototype is available via anonymous ftp from
ftp.cs.colorado.edu [128.138.243.151] in /pub/cs/distribs/essence.
The distribution includes the following files and directories:
README This file.
INSTALL Instructions on how to install Essence
Makefile Top-level Makefile
ChangeLog List of changes
ToDo List of bugs-to-fix and future enhancements
doc/ Manual pages, Frequently Asked Questions,
1993 Winter USENIX paper, and other information.
src/ Source code for Essence and its supporting tools.
We would appreciate comments and suggestions about Essence. When
reporting bugs, please include the version number (listed at the bottom
of this file). If you feel enterprising, take a look at the
suggestions of things in the ToDo file. Also, note that Essence
selectively chooses "promising" keywords for the indexes, based on
knowledge of the semantics of individual file types (e.g., extracting
author, title, and abstract from troff documents). We would appreciate
it if people try Essence and suggest better ways to select keywords
based on thier experiences.
