About Expert Rules

Creating an Expert Rule: Select the Expert rule icon to create an expert rule, write its body, test its syntax and add it to your rule base.

An expert rule is a set of instructions whereby you can start an action for any object having a type defined in a type list.

The action can be a message which does not modify the document. More generally it consists of a set of instructions modifying the document. The action specified in a rule can be conditionally executed depending on the value of one or more expressions. In an expert rule, objects are manipulated through their attributes and methods (if any). This applies to checks too.

An expert rule is made up of two parts:

The (for all) field in which you define the types list the rule applies to:
S:Shell ; H:Hole

The rule body:
if (S.Activity == true) AND (H.Activity == true ) Message ("All shells and holes are activated")

To apply an expert rule to a document, solve the entire rule base.
