16. The computer system of claim 15 , wherein identifying change statuses includes: identifying, for the respective source and target models, correspondence among the initial and post-change segments.
15. A computer system comprising: a processor; and a storage device connected to the processor, wherein the storage device has stored thereon a computer application model conflict reconciling program for controlling the processor, wherein the computer application models include i) an initial source computer application model, ii) an initial target computer application model generated by applying at least one transformation rule to the initial source computer application model, iii) a post-change target model produced by at least one change to the initial target model, and iv) a post-change source model produced by at least one change to the initial source model, and wherein the processor is operative with the program to execute the program for performing: automatically dividing the initial source and target models and the post-change source and target models into segments responsive to at least one segmentation rule, wherein the at least one segmentation rule is defined responsive to the at least one transformation rule such that use of the at least one segmentation rule divides the initial source and target models into corresponding, isomorphic segments, wherein the initial source and target models have an isomorphic structure in common on which to mark changes; automatically identifying change statuses of the initial segments relative to the post-change segments of the respective models responsive to comparing initial segments to post-change segments of the source model and initial segments to post-change segments of the target model; and automatically generating, on a data structure representing the in-common isomorphic structure, an indication of conflicts between the post-change source model and post-change target model for presentation to a user or to a computer automated conflict settlement process, wherein the generating is responsive to comparing the identified change statuses of the corresponding, isomorphic segments of the initial source model and initial target model, wherein at least part of the identifying and generating occurs after changes to both the initial source model and the initial target model.
