Through a model, you specify initial properties for objects of a specific class.

For example, you can ensure that a special set of risk-related properties is present on all instances of class Data-Loan-Aircraft-SingleEngine. When a page of this class is created, you can instruct the system to apply a model, named Aircraft-High-Risk. The system places into the page the risk-related properties defined in the model. When the page is later saved into the database as a persistent instance, the properties are present with meaningful values.

Four methods use a model as a parameter: NOT Page-Merge-Into

• Apply-Model — Updates an existing page with values computed from a model rule. 5.4
• Page-New — Creates a new named page of a specified class based on the model and places the model data into the page.
• Page-Copy — Copies the contents of a source page to a new named page or replaces the contents of an existing page, and also places the model data into the page.
• Page-Change-Class — Creates a new page of the specified class and model, and then merges properties from another page into it.

Service rules (Rule-Service- classes) and a few other rule types can reference a model. The model is applied at runtime to a newly created page.
