US Patent 7664776 Methods and apparatus for dynamic form definition

A system provides a form manager that defines an electronic form comprising a field to populate with a data object. The form manager further defines a schema associated to the form. The schema describes the data object. The form manager further defines a variation rule for the electronic form. The variation rule describes a variation that may occur in the data object. The variation rule represents variation processing to be dynamically applied to the electronic form in response to detecting the variation.
