TSCG's purpose is to provide an introductory-level toolkit to learn, practice and explore systems modeling. Its mission is to help you build scale models of systems: deliberately simplified, working models made for learning by doing. It rests on three pillars.
What TSCG is not. It is not a new Grand Unifying Framework and claims no universal theory. It is judged by its internal coherence and by how useful it is for building model mock-ups.
The Layer Cake. Four levels of ontologies (M3 Structural Grammar, M2 Generic Concepts, M1 Domain Adaptation, M0 Instances) give the kit a coherent, ontology-driven architecture: each layer rests on the one below, and the acceptance gate checks that they fit together.
Pick your level — the Compendium shows only what concerns you.
