4.2.277 Incremental_model_change

An Incremental_model_change is a mechanism to describe the differences between two Geometric_model or Styled_model objects with respect to geometry, style, or presentation. An Incremental_model_change states the fact that a base model has been modified and that the modifications have been included in the base model.

NOTE Incremental_model_change objects may be chained resulting in a hierarchical description of modifications over time.

An Incremental_model_change is a type of Model_change.

The data associated with an Incremental_model_change are the following:

4.2.277.1 added_element

The added_element specifies the elements that have been added during the change in a container providing the coordinate space for these distinct elements.

See incremental_model_change to geometric_model and incremental_model_change to styled_model for the application assertions.

4.2.277.2 basis_model

The basis_model specifies the Geometric_model, Styled_model, or Incremental_model_change that is subject to the changes.

See incremental_model_change to geometric_model, incremental_model_change to incremental_model_change, and incremental_model_change to styled_model for the application assertions.

There shall be exactly one object that defines the basis_model for an Incremental_model_change.
