A Software Hub for Model-Driven Development

The WW Technology Group (WWTG) Software Hub provides coherent views of system organization and behavior by integrating architectural and analytical models of systems and architectures. With a foundation in the architectural representations available through the Architecture Analysis and Description Language (AADL), and a flexible set of extensions that support the integration of additional modeling and analysis tools, the power of each modeling and analysis tool is retained while ensuring that a consistent view of the overall system configuration is retained. WWTG extends its EDICT modeling environment by developing the software hub approach using the AADL Open Source AADL Tool Environment (OSATE) that is based on Eclipse, an open development environment perfectly suited for the integration of tool suites. The AADL architectural view of the system provides a common reference for the organization of the system behavioral properties. With extensions to AADL referencing and specifying system behaviors, users of the language and corresponding tools are afforded with the best of the architectural, model, and simulation worlds. By leveraging the organizational properties of AADL, model based information is kept in a normalized form, with model based descriptions being coupled into the AADL model at the appropriate levels of system abstraction.
