This page gathers concrete system examples that exercise TSMM as a modeling surface rather than as description alone.
A meta-model becomes easier to adopt once it can express real systems. These examples are intentionally compact, but they are concrete enough to show how registry, federation, directory, content authenticity, and community trust systems can be described using the same graph vocabulary.
They are also meant to be copied. In practice, most contributors should start from the nearest example, adjust the nodes and edges, and then validate the result rather than beginning from an empty file.
If you want the smallest graph that still expresses the full TSMM path, start with:
model/graph/tsmm.graph.jsonThat file is the canonical graph-first reference for the repo.
