ABSTRACT:
A method and system are provided in which data may be multityped using a schematized data model. A standardized schema in a schematized data model includes at least one base construct for representing data that is common across multiple types of an object that the model represents. An extension to the standardized schema is at least one extension construct for representing data that is specific to a single type of the multiple types of the object. Instances of the extension construct are directly or indirectly associated with exactly one instance of the base construct without impacting the behavior and functionality of the base construct. Multiple extensions may be used to represent data that is specific to each of the corresponding multiple types of the object.
