Registering rules for entity attributes for validation and inference

A system for describing entity attributes in a modeling application, the system comprising:

• a modeling engine for generating a system model in a modeling application, wherein the modeling engine generates an entity with one or more attributes associated with the entity;
• a rules engine for defining one or more rules, wherein at least one of the one or more rules comprises a constraint on a value of the one or more attributes of the entity;
• and
• a validation and inference component for registering the one or more rules.

A computer-readable medium having computer-readable signals stored thereon that define instructions that, as a result of being executed by a computer, instruct the computer to perform a method for describing entity attributes in a modeling application, the computer-readable medium comprising:

• instructions for generating an entity in the modeling application, wherein the entity includes one or more attributes associated with the entity;
• instructions for defining one or more rules, wherein at least one of the one or more rules comprises a constraint on a value of the one or more attributes of an entity;
• instructions for registering the one or more rules with an entity validation and inference unit;
• and
• instructions for generating validation code based on the on the one or more rules.
