Cybernet is developing an Application Coherency Manager that implements and manages the interdependencies of simulation, data, and platform information. It will also enforce a simulation configuration profile submission that includes the specification of the interdependency requirements. To describe these interdependences, a general-purpose language will serve as the basis for higher-level rules that are assembled using a higher-level graphical user interface. Additionally, we are implementing a graphical user interface that allows the user to manage and assemble rule-profiles. Rule profiles are created by assembling and parameterizing one or more low-level code modules. This user interface will then save these profiles into a revision archive alongside the applications and the data sources. The profiles themselves are stored as XML-based documents that refer to the low-level data-source checker modules.
