An approach to form creation based on AND/OR tree

A basic framework for the design of a prototype form system, CRAFT, is proposed. CRAFT enables users to create (i.e. define and realize) forms with various structures. Form creation is an integrated concept of form definition and form realization. For form definition, a formal form model is introduced. Form realization is specified by using a create graph based on AND/OR trees. CRAFT supports a visual language that provides naive users with an easy visual programming method.<
