OAA 1.0 Distribution
About the Download Distribution
This distribution provides everything you will need to run
an OAA system under either Windows or UNIX. The distribution also
provides agent libraries for various languages to create your
own OAA agents.
The current version of the download distribution is 1.0.2. Please
see release notes on the main "Distribution Information" page.
The Facilitator agent (OAA v1.0) is available for Unix (Sun) and PC
platforms. The Facilitator may be downloaded separately here,
and is also included in the OAA 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. Then
you can create your own agents and applications by downloading
the appropriate Agent Libraries.
- OAA 1.0 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 Agent: Rapidly define OAA agents in the Compaq's Web Language
to extract information from the web.
- Sample Application including:
- DCG-NL Natural Language Parser
- Database Agent and domain file for worldwide city information
- WebL script for finding weather from cities
- WebL script for extracting employee info from simple web
Agent libraries are provided for a number of languages, each with a
very simple sample agent which uses the library. The sample agent in
each case simply illustrates how to include the OAA library, declare
a simple capability, and define the callback for the capability. To
create more complex agents, please see OAA 1.0 documenation, paying
particular attention to the
OAA 1.0 Developer's Guide
and the OAA Tutorial.
Quintus Prolog 3.2
The agent library for Quintus Prolog is delivered as a Quintus QOF
file and is portable across any platform Quintus supports (Sun, SGI,
PC Windows). We have not yet tried this library under QP 3.3, but it
may work -- please let us know!
The sample agent can be run from the Prolog interpreter (load the
agent and run the main procedure: start_agent(a)), or compiled
to an executable with the following commands:
qpc -c a.pl
(for PC): qld -do a.exe a.qof agent.qof
(for Unix): qld -S -d -o a a.qof agent.qof
The agent library for Java is delivered as a JAR file containing an
OAA Javabean. The JAR file is portable across any platform Java
supports. A tiny agent which registers a "fax" capability with the
facilitator is included below as an example.
The Java OAA library also comes with a second JAR file containing several
useful dialog boxes (one for requesting host/port information, one
for displaying help in a Web browser, one for creating a simple about
box). OAA agents usually use all of these functions, but note that they rely
on Java's SWING classes and on a freeware webbrowser component. As
an example of a more complete OAA agent in Java, we have provided
complete source code to the OAA Debug Interface tool shipped with the
OAA Runtime Distribution.
The agent library for Lisp is contained in a single Lisp file, which imports
the C library, in compiled form, using the foreign function interface
of the Lisp system. At present, it may be used with Allegro (v. 4.x
and higher) and
Lucid/Liquid Lisp products under Unix. It has also been used successfully with
Allegro under Windows, in conjunction with the Windows Console DLL
The required C library source code, for use under Unix, is included.
(It's the same, or very nearly the same, as is included in the C Unix distribution elsewhere on
this page.) The Solaris binaries compiled from this C code are also included.
If you are not working under Solaris, this distribution includes a
simple make file for building the appropriate object files from the
Also included are sample source files for 2 trivial Lisp agents, one
of which sends a request to the other.
The C agent library for Windows is a DLL that can
be loaded by agent programs. The distribution contains the DLL
and an example of a simple agent. In addition, the distribution contains
MS Visual C++ (V5) project files and source code to the OAA 1.0 agent library.
C (Windows Console)
This distribution contains a DLL specifically for use with "console"
applications; that is, applications that do not create any Windows, or
that do not want to receive agent events in the Windows
event queue. At present, this is the only DLL that can be used with
our Lisp library.
As with the C Windows distribution above, this distribution includes
an example of a simple agent,
MS Visual C++ (V5) project files and source code to the OAA 1.0 agent
This distribution includes the C agent library for UNIX and makefiles
to generate libraries for console (liboaa.a) and Motif (liboaax.a) based
applications. It also includes two examples of simple agents, one
console and one based on Motif.
(Note: at some future point, we expect to combine the three C
libraries listed above into a single distribution.)
This perl library was tested under Unix, and may also work under PC.
