Part 2 – System-Specific Metamodel and Libraries

The systems package contains domain-specific terms that support systems engineering. It includes terms to describe the composition of systems from parts, functional decomposition and allocation, interface control, requirements,
validation and verification, integration and test.

The systems package also tries to present terms that are familiar to engineers rather than the more logically-oriented kernel language. For example, Definition and Usage are used as the intent of constructing models from reusable
pieces rather than Typing which is a more programming / logical concept.
