You use the ArchitecturePrinciple template to document architecture principles – meaning rules you have defined or adopted to document a coherent enterprise architecture. You can link the ArchitecturePrinciple to the FrameWorkCells they apply to under the FrameWorkCell’s Architecture principles field under the ‘relations’ tab. You can also link the architecture principle directly to the ArchitectureFramework’s properites under its Principles-field.
