A new software architecture for supporting inter-object consistency management is described. Objects with interdependent data values are kept consistent by propagating descriptions of object state changes along inter-object relationships. Response to and storage of these change descriptions supports the implementation of consistency management techniques in a more homogeneous way than existing models. Such techniques include efficient attribute recalculation and constraint schemes, multiple view consistency, and undo-redo, versioning and cooperative work facilities. Applications of the new architecture to user interface, graphical editor and programming environment construction are described.
