Rule Model Extension Schema

You can define rule model extensions to create a new type of rule artifact or rule package, or to add properties to existing rule model classes.

You can also insert your own code, at specific extension points: for example, to hide a specific property, or to call some code after a property value is changed.

Extension Schema

You define rule model extensions with XML files. The main XML file is the extension model file, which defines the structure of the extension. You can associate an extension data file to the extension model file, which defines the values of enumerations or hierarchies. You then need to register these files in Rule Studio and Rule Team Server.

Two schemas are provided to define the structure of your extension model and data files:

Default Extension Model

Extension model and data files are provided by default. You can use the content of these files as the basis for your custom rule model extension files.

In these files, the following properties are set:

Table 1 Default Extension Model

Rule Model Class	Property	Type	Values (defined in the extension data file)
`Rule`	effectiveDate	`Date`	-
	expirationDate	`Date`	-
	status	`Status`	new, defined, validated, rejected, deployable
`BusinessRule`	priority	`String`	-

The properties of Rule and BusinessRule are put into the ruleset when you extract it.
