Abstract
A reproduction structure in a computer is based on a hierarchical structure of consistency relations between objects. As a function of one or more objects of a given hierarchical level, each relation specifies one or more incremental objects at a next-higher level. Variable incremental objects are situated at the lowest level. After a user interaction, modifying one or more variable incremental objects, the consistency is restored as follows. First a set of value inconsistencies is signalled for the incremental objects during a bottom-up signalling step. Subsequently, on the basis of each element of said set during a top-down updating step the value of the hierarchically higher object is updated on the basis of a change of value, if any, of associated, specifying variable incremental objects and/or incremental objects.
