Federating models for handoff
The systems engineering model is, at least abstractly, a single model. In practice, large systems engineering models may be split up into multiple projects (roughly, but not precisely, "models"), but that is done for convenience. Logically, it is a singular coherent model with the systems engineering data.
Downstream engineering is different in that many separate, independent models will be created. These models will interact with each other in specific and well-defined ways. A set of such independent, yet connected models is called a federation, and the process of creating the models and their linkages is called model federation.
One of the key ideas in model federation is the notion of a single source of truth. This concept means that while there may be multiple sources for engineering data, each specific datum is owned in a single, well-defined location known as the datum's authoritative source. When a value is needed, the authoritative...
