Methods and apparatus for information modeling, such as product modeling, are described. In one specific embodiment, a system for capturing product information includes a product definition tree representing permitted elements of a generalized product structure, a plurality of template trees and a plurality of configuration trees. Each template tree represents a product design structure variant which represents a subset of said product definition tree. Each configuration tree represents a particular design configuration, which is constrained to implement the structure of its associated template tree.
