This file is the entry point for an AI agent (or any automated tool) ingesting this repository. It tells you what to read first and which artifacts are machine-readable.
Meta-Universe is a family of open standards for federated semantic systems: how independent "universes" of meaning describe reality, build meta-models, and federate knowledge while preserving identity, context, ownership, trust and traceability. It is a specification, not a runtime.
spec-index.yaml— the machine-readable index of every document (id, class, status, path). Start here to enumerate the spec.00-foundation/Terminology.md— the normative vocabulary. Resolve terms here, not from prose.01-constitution/Meta-Universe-Constitution.md— the fundamental laws (21 articles). Each normative statement has an ID (MUC-Rnn).REQUIREMENTS-INDEX.md— every RFC 2119 requirement across all normative documents, with stable IDs. Cite these IDs.02-architecture/MMAS-Interchange.md+schemas/— the MUIF serialization and JSON Schemas: the concrete, validatable face of the model.03-federation/MUFP-Messages.md— the wire protocol (envelopes, state machine, errors) for federating.
| Artifact | Use |

examples/minimal-person/— smallest model + fingerprint reproducibility.examples/federation-acme-govtax/— two universes federate end-to-end.examples/federation-handshake/— a MUFP message transcript.examples/interop/— mapping to RDF/OWL, Schema.org, FHIR, FOAF.examples/data-bindings/— portable Git/Markdown, SQL and MCP/HTML bindings.
If you were pointed at a model repository (it has BOOTSTRAP.md,
manifest.yaml, sources.yaml), your operating instructions are
07-guides/Agent-Operations.md: read BOOTSTRAP → manifest → sources before
content; walk bundles in declared order; write only to the dataset's
declared master; never hand-edit raw/, mirrors or artifacts/; re-run the
coverage walker after structural changes; refuse writes when mastership is
undeclared. The connected human-readable map of the whole standard is
00-foundation/Overview.md.
See 07-guides/AI-Integration-Patterns.md and 07-guides/AI-Agent-Guide.md:
load meta-models as tool schemas, retrieve meaning via Projections + Events
(not raw rows), enforce an Executable Semantic Contract in the loop, and produce
traceable results.
- Treat Terminology and the Constitution as authoritative; do not infer normative meaning from informative prose.
- A model "means the same thing" iff its Semantic Fingerprint matches.
- Never treat schema discoverability as data access.
