About the Download Distribution

This distribution provides everything you will need to run and develop an OAA system under either Windows or UNIX. You will need to download at least the Runtime Distribution for your platform(s) of choice, and if you would like to see source code to the libraries or tools, may additionally download the source distribution.

Although OAA 1.0 supported many languages (Java, C, C++, Prolog, Lisp, Visual Basic, Borland's Delphi, Compaq's Web Language, Perl), OAA 2.0 currently supports four: Java, C, Prolog, and WebL. Full source code to these libraries are included as part of the Source Code Distribution, so feel free to help us port them to other libraries. The Lisp library is under construction now.

Please see the release notes on the main "Distribution Information" page.

Runtime Distribution

The Runtime Distribution includes the OAA Facilitator, a number of runtime and debugging tools for managing the agent community, and a sample application featuring simple natural language access to a dynamic collection of web sources (weather for national and international cities, a sample employee database). This distribution should enable you to run and understand an OAA system. You are then free to create your own individual agents and multi-agent applications.

This runtime distribution contains all binaries, java jar files, and scripts required to run the OAA tools and sample application. If you would additionally like source code for the distribution, go to the OAA Source Code Distribution section below.

The Java components of OAA 2.0 use Java JDK 1.2.x.

Contains:

OAA 2.0 Facilitator
OAA Monitor: graphically trace and profile agent community
OAA Start-It: launches a community of agents, and restarts agents if they unexpectedly terminate
OAA Debug Interface: Send queries and messages to the agent community or to an individual agent, using English or the Interagent Communication Language (ICL)
OAA-WebL Library: Rapidly define OAA agents in Compaq's Web Language (previously known as WebL) to extract information from the web.
Sample Application including:

DCG-NL Natural Language Parser
WebL script for finding weather from cities
WebL script for extracting employee info from simple web database

Download:

Unix (tar.gz: 8.2Mb):
PC (zip: 1.45Mb): Windows 9x/NT

Please note: If you download the Unix distribution using Netscape on a Windows platform, you may find that it renames the file. If so, just correct the name manually, following the download, to "oaa_runtime_2_0_xx.tar.gz".

Carefully follow the instructions in the README FILE when setting up the runtime distribution.

"Patches":

The Sicstus-generated facilitator for Linux/x86 has had several things fixed since the 2.0.12 distribution was posted (above). If you are using it, or want to use it, download the following two files (fac_sics and fac.sav) and copy them into the appropriate directory (oaa2/runtime/prolog/linux-x86).
See oaa-users mail archive message of Oct. 10 for a brief discussion of this.
- fac_sics.gz
- fac.sav.gz
The JAR file for StartIt was found not to work under Windows 2000, and Matt Ginzton contributed source code to fix the problem. (See oaa-users mailing list thread "startit and Windows 2000" at the February archives page). The following build of the JAR file incorporates the fix.
- oaa2startit.jar

"Pre-release":

Attain NL agents. Solaris only. (These will be included in the upcoming 2.1.0 release.)
- attain_nl_agents.tar.gz

Source Code Distribution

The source code distribution provides source code to everything in the runtime distribution except for the Facilitator agent. Scripts and makefiles are included to facilitate compilation using Java JDK 1.2 and Quintus Prolog v3.2.

Note: the source distribution does NOT include any binaries (including the Facilitator), so you will still need to download and install one of the runtime distributions. The source tree is compatible and complementary to the directory structure of the runtime distribution.

Download:

The source distribution includes everything for both Windows and Unix environments, but for convienience, has been listed twice below, once compressed as a zip file and once as a gnuzipped tar file.

Source Code Distribution (tar.gz: approx. 2.4MB)
Source Code Distribution (zip: approx. 2.65MB)
Prolog source file spcompat.pl.

Notes on C library

The Source Code distribution now includes source code for the OAA2 C library, the debug agent ported to C as an example, and a simple OAA2 C sample agent. Makefiles and MS Visual C++ (Ver 6.0 and later) project files are provided to regenerate the library and the examples. Correspondingly, the Runtime Distribution now contains a compiled version of the library (liboaa2.a for UNIX and LINUX, liboaa.dll for Windows) and executables for the debug agent.

The debug agent is a GUI-based agent, built on top of an excellent lightweight and multi-platform framework called fltk. Even though we included all fltk components needed to compile our examples, we invite you to visit the official fltk website for complete information and documentation.
