These are notes intended for developers and technical users.
- File syntaxes
Describes the syntaxes supported by I-X, says how to find
which syntaxes are available in an I-X Process Panel, and
describes some of the file-syntax utilities that I-X
provides for Java code.
Aspects of Process Panels
Explains options -- alternative plans or courses of actions --
and how they can be used in an I-X Process Panel.
- Test menus
How to write test menus for an I-X Process Panel. A test menu
typically specifies items such as issues and activities that,
when selected, are sent to your panel or to another agent.
This allows you to set up items in advance for demonstration,
testing, training, and other purposes.
- Object-Viewing "Whiteboards"
Describes a viewing tool that represents objects and their
properties as an HTML table and allows editing of a reasonably
- Synchronized state
Describes a way for agents to keep their world-state models
in sync with each other.
- Exporting state
Describes an experimental mechanism that can be used to
tell an I-X Process Panel to automatically send some of
its world-state changes to other agents.
- LTF syntax for domains
Describes a language (List Task Formalism, or LTF)
for defining domains. It has a Lisp-like syntax
that is more compact and readable than the
- Using checklists as domains
Describes how to use a "checklist" syntax for I-X domains.
- I-DE object models
Describes how to define and use object classes and properties
in the domain editor I-DE.
- Object classes
Describes how object classes and properties are represented
in domain definitions in XML and LTF syntax.
Notes on using an I-Plan panel; also describes the annotations
that affect planning.
- Compute conditions
Explains "compute" conditions: constraints that are evaluated
by calling functions and hence can be used to perform calculations,
manipulate data structures, etc.
A programming language that can be used to define funtions
that are called by compute conditions.
- LTF syntax for plans
Describes how plans can be represented as domains and
the how LTF (List Task Formalism) language can be used
to describe such domains.
Other I-X agents
- An I-X HTTP server.
- BNF-generator for the XML syntax
An interactive utility that asks the user for a class name
and outputs a BNF-like description of the I-X XML syntax
for that class and any related classes that it knows about.
- Standalone file-to-file planner
A non-interactive utility that runs I-Plan on a planning problem
specified by an initial plan and a domain.
Translates files from one I-X syntax
- I-Script interpretor
A standalone interpretor for the I-Script
language. The interpreter can be used to test code that's
meant to support "compute" conditions and that's attached
to domains or defined by
Notes on writing plug-in modules and extensions
- Writing a communication
Describes how to write a mechanism for sending objects between
- Writing a state viewer
Describes how to write a viewer for the world-state model in
an I-X process panel.
- Writing an agent extension
Describes how to use a general-purpose mechanism for adding features
to I-X agents. In effect, it lets you specify some Java code that
is invoked when the agent starts up and can then take advanatge of
any points the agent has for adding or plugging-in new abilities.
It also describes two such cases: adding a tool in an agent that
has a "Tools" menu, and defining functions that can be called in
- I-X XML Syntax
Gives several different descriptions of the way I-X represents
information in XML, including an XML schema and a Relax NG
schema as well as a BNF-like grammar and a less formal
description. The close correspondence between the XML
and the classes used to represent the same information
in I-X means that the XML descriptions also serve as
descriptions of the classes.
Describes the parameters than can be given via command-line
arguments or property files to the main types of I-X agent.
