Abstract

Embodiments of the invention can be used to assess whether a software application is compatible with an operating platform. A specification that describes the operating platform is generated using a definitional language. The specification identifies the programming resources of an operating platform. The application'"'"'s dependencies and programming resources are identified. A compatibility engine is executed to resolve an application'"'"'s dependencies to the specification. The output of the compatibility engine identifies whether the application conforms to the operating platform and how it deviates from the specification.
