Subject: RLF 2.2 now available
Date: Fri, 20 Sep 91 22:33:25 EDT [thread overview]
Message-ID: <9109210233.AA15375@aviary.Stars.Reston.Unisys.COM> (raw)
Version 2.2 of the Unisys STARS Reusability Library Framework (RLF) is
now available in both source code and binary forms via anonymous FTP
from host "stars.rosslyn.unisys.com" in directory "pub". The source
code release is in file RLF_2.2.tar.Z and the binary release is in
file RLF_binary_2.2.tar.Z. Both these files are compressed Unix tar
files.
The RLF is a knowledge-based software system designed and implemented
by Unisys Defense Systems under the auspices of the DoD Software
Technology for Adaptable Reliable Systems (STARS) program, primarily
to enable the development of domain-specific reuse libraries.
The RLF, implemented in Ada, is extensible and is integrable with
other Ada systems. The RLF includes a semantic network subsystem
(AdaKNET) and a rule-driven inferencing subsystem (AdaTAU) which are
used to record domain knowledge and heuristics in a form suitable
for use within Ada applications, such as reuse library browsing and
management tools. It runs on Sun 3 and Sun 4 workstations with
SunOS 4.0.3, 4.1 or 4.1.1, and is compilable with the Verdix 6.0.3
Ada compiler.
The RLF comes with a Graphical Browser tool for inspecting AdaKNET
networks graphically via an X Window System interface. This interface
is built on the Unisys STARS Reusable Graphical Browser (RGB), version
0.4.1, and the Unisys STARS Ada/Xt implementation, version 3.2, and these
products must be obtained in order to build the RLF graphical browser
from source code. They can be obtained via anonymous FTP from the same
host and directory in which the RLF resides. Appended to this message
are the Ada/Xt and RGB entries from the README.catalog file included in
the FTP directory.
RLF 2.2 features substantial enhancements to the RLF Graphical Browser
application, providing a richer set of capabilities for navigating
within library views, a basic inferencer invocation capability, a pattern
matching search capability, a set of view management enhancements, and
a variety of performance enhancements and bug fixes.
Both the RLF source code and binary releases include the RLF AdaKNET,
AdaTAU, Librarian, and Graphical Browser User Manuals, as well as a
Version Description Document that describes this version of the RLF
and provides installation instructions. The documents are provided
in both plain ASCII (suffix ".tty") and Postscript (suffix ".ps0"
[in some cases] and ".ps") forms, in the files listed below:
VDDrlf
docs/UserManual/AdaKNET_User_Manual
docs/UserManual/AdaTAU_User_Manual
docs/UserManual/Librarian_User_Manual
docs/UserManual/RLF_Graphical_Browser_User_Manual
If you do not have FTP capability, you may obtain the RLF and its
supporting software on tape from the Unisys STARS Center. If you
have questions about this or other RLF issues, please contact me
for further information.

The Ada/Xt and RGB catalog entries:
===============================================================================
Filename: AdaXt_3.2.tar.Z
Filetype: compressed tar
Item: Ada/Xt Toolkit,
Version 3.2,
SunOS Implementation
Description:
This is the Unisys Ada implementation of the Xt toolkit (Ada/Xt), version 3.2.
Included in this package are Unisys revisions to Version 1.0 of the STARS
Ada/Xlib Bindings produced by Unisys, Boeing, and SAIC, an Ada implementation
of the Xt intrinsics that is compatible with the joint STARS Xt interface
specification, and an Ada implementation of a sample widget set. The Xlib
bindings are compatible with X11R3 and X11R4.
Also included in this release are the Ada/Xt Style Guide and the Ada/Xt Version
Description Document, which describes this version of Ada/Xt and provides
installation instructions. These documents are provided in both plain ASCII
(suffix ".tty") and Postscript (suffix ".ps") forms, in the files listed below:
adaxt/VDDxt
adaxt/Style_Guide/styleguide
Update Information:
Open Windows compatibility enhanced.
Memory leaks patched.
Text widget improved.
===============================================================================
Filename: RGB_0.4.1.tar.Z
Filetype: compressed tar
Item: Reusable Graphical Browser (RGB),
Version 0.4.1,
SunOS Implementation
Description:
This reusable software component implements a graphical user interface
for viewing the contents of an object management system. Its purpose is to
facilitate the construction of various browsing tools, serving as the user
interface component of those tools. The generic application interface and
tailorable user interface promote portability of graphical browsing tools by
isolating them from the underlying graphics system. Tool builders need not be
familiar with the intricacies of graphics packages or windowing systems to use
this product.
RGB is implemented in Ada, with the exception of one small routine, coded
in C. The implementation is compatible with Version 11, Releases 3 and 4 of
the MIT X Window System and is dependent upon the Unisys STARS Ada/Xt Toolkit.
The release includes the RGB User Manual, and the RGB Version Description
Document, which describes this version of RGB and provides installation
instructions. The documents are provided in both plain ASCII (suffix ".tty")
and Postscript (suffix ".ps") forms, in the files listed below:
browser/VDDrgb
browser/docs/UserManual
Update Information:
Improved scrolling, error detection, faster view changes.
Added refresh for suppressed displays.
