Arden Syntax:Implementation Guide

Implementation Guide Arden Syntax

This page will collect material for a Arden Syntax implementation guide

General Outline

Syntax Description Part (basically taken from Medexters HowTo)

• Arden Syntax – Fundamentals (what is a MLM, how are they represented)
• Basic MLM Layout (categories and slots and their duty)
• Identify an MLM (name, institution and version)
• Data Types (basic types, Fuzzy Sets, Truth Value as well as Primary Time and Applicability)
• Expressions (basic expressions and Curly Braces)
• Statements (basics and control statements)
• Operators (some basic operators)

Basic tasks (by example)

• common tasks (e.g. search a list for a specific value, sort a list of objects etc.)
• small snippets of MLM code on how to solve specific problems (e.g. in former versions it was not possible to convert a String into a Date, this section should explain on how to do this)
• call sub MLM
• create complex knowledge bases with MLMs

Use Cases (how to implement ...):

Every use case should contain at least one example MLM.

• decision trees/tables
• production system
• state machines / transitions
• guidelines
• fuzzy control
• (any other ideas ?)
