A method for cross-platform porting of applications includes extracting one or more platform independent models from an existing one or more composite applications running on a given source platform. These platform independent models are then transformed into implementation artifacts on another, target platform, thereby effectively porting the composite application from one platform to another. The generated implementation artifacts on the target platform leverage existing assets in the target environment, which makes these generated artifacts 'contextually-aware'.

System and a method for cross-platform porting of business application and making them contextually-aware on target platforms

A method for generating implementation artifacts for contextually-aware business applications includes utilizing a platform independent model (PIM) of a business application; generating a platform specific model (PSM) from the PIM, wherein the generating of a PSM includes one or more transformations between one or more meta-models of the PIM and one or more meta-models of the generated PSM; generating implementation artifacts; and binding the generated implementation artifacts with any existing services of the business application.

System and method for generating implementation artifacts for contextually-aware business applications

A system and method for extracting a platform independent model (PIM) from the existing implementation artifacts of a composite application via an intermediary platform specific model (PSM) using model-driven transformations. Meta-models for the PSM and PIM are prepared and mapping rules are specified therebetween. The mapping rules can be created manually or derived automatically via ontology mapping techniques. Once specified, model driven transformations that codify the mapping rules generate the PIM which may include the structural, behavioral and user experience models of the composite application. To enhance the reusability of the extracted PIM, a business level service model along with a service dependency model is generated rather than IT level classes. These higher levels of abstraction enable the models to be linked with business objectives, which is important for companies to understand and maintain their service portfolios.
