NASA Integrated Model-Centric Architecture (NIMA) model use and re-use

This whitepaper accepts the goals, needs and objectives of NASA´s Integrated Model-centric Architecture (NIMA); adds experience and expertise from the Constellation program as well as NASA´s architecture development efforts; and provides suggested concepts, practices and norms that nurture and enable model use and re-use across programs, projects and other complex endeavors. Key components include the ability to effectively move relevant information through a large community, process patterns that support model reuse and the identification of the necessary meta-information (e.g. history, credibility, and provenance) to safely use and re-use that information.
