US Patent 7861214 Computer method and apparatus for collapsing programming metamodels

Computer method and apparatus collapse program metamodels to provide a collapsed, in syntax view of the subject metamodel. The invention method and apparatus obtain multiple programming model packages. Each said package is formed of a respective plurality of model elements from the subject metamodel. Next the invention combines (e.g., collapses) the multiple programming model packages together to form a resultant collapsed package. The resultant collapsed package enables generation of an implementation of a desired software program and avoids the need for package links (representing package merge relationships between packages).
