Transformation of logical data object instances and updates to same between hierarchical node schemas

Abstract:

Update elements allow logical data object instances, and change requests therefor, to be converted from a first schema to a second schema. For logical data object instances, a transformation function can add nodes to, or remove nodes from a hierarchy of the first schema, or rearrange them. Use of the transformation function can allow second schemas to be defined that change a node hierarchy, yet can be used with existing logical data object instances in the first schema. Changes to logical data object instances can be converted using a mapping or a transformation function, such as a transformation function useable to convert logical data object instances between the first and second schemas. The migration of change requests to the second schema can allow logical data object instances having previously scheduled change requests to be updated from the first schema to the second schema prior to execution of the change request.
