  • Patent number: 8122443
    Abstract: Embodiments of the present invention provide a method, system and computer program product for a dynamic multi-context delta view for merging structured data in a visual merge tool. In one embodiment of the invention, a method for providing a dynamic multi-context delta view can include rendering a compare view of a merged state for a selected model to include model controls each corresponding to a different model state for the selected model. The method further can include detecting a transient proximity event in connection with a particular one of the model controls. The method yet further can include identifying a corresponding model state for the particular one of the model controls. Finally, the method can include replacing the merged state with the corresponding model state in the compare view.

  • Publication number: 20080275895
    Abstract: The present invention provides a model identity re-alignment algorithm that allows models with similar structures but substantial identity differences to be aligned such that all similar elements have the same identity. This causes the two models to appear to have come from a common ancestor. Once the two models have been aligned with one another, it can be used as a contributor in a two or three way merge and thus, becomes a part of the normal development work flow. This allows any two models to be aligned and then participate in a normal version control work flow. It also helps eliminate massive numbers of trivial differences. It addition, it is simpler and less error prone than manual systems.
