# Reference Repository **Meta-Universe Specification** **Document ID:** MU-V2-REFARCH-006 **Title:** Standard Repository Example **Document Class:** Informative **Version:** 2.0 (Draft) **Status:** Working Draft **Normative References:** Meta-Universe Constitution (MUC), MMAS, MUFP **Informative References:** Architecture, Naming Examples **Copyright:** © Orkestron.AI **License:** Apache-2.0 --- # 1. Purpose This document defines the recommended repository structure for Meta-Universe compliant specifications, domain Meta-Models and semantic packages. The Reference Repository provides a common organizational model that improves discoverability, interoperability, governance and long-term maintainability. The structure is recommended as a reference architecture but may be adapted where justified without violating MUC, MMAS or MUFP. --- # 1a. Meta-Universe as a Standard of Knowledge Publication The Meta-Universe is not only a way to *build* semantic models; it is also a standard for *publishing* them. The family of standards divides this responsibility cleanly: - **MMAS** defines *how to build* models — their architecture, versioning and validation. - **MUC** defines *the laws* every model and exchange obeys. - **MUFP** defines *how models interact* across sovereign Universes. - **The Reference Repository** (this document) defines *how models are published* — the common organizational form in which knowledge is made discoverable, verifiable and federatable. This mirrors how other ecosystems separate creation from publication. Git stores history; GitHub publishes code. OpenAPI publishes APIs. OCI publishes containers. In the same spirit, **the Meta-Universe publishes semantic models** — and the Reference Repository is the canonical layout that makes a published model recognizable to any human or AI agent that encounters it. A repository organized this way is itself a kind of Projection of the knowledge it contains: a predictable surface that exposes foundation, architecture, federation, core concepts, domain models and guides in known locations, with known metadata, so that consumers can navigate, validate and federate without prior arrangement. --- # 2. Design Principles A conforming repository SHOULD be: - human-readable; - AI-readable; - Git-native; - modular; - versioned; - traceable; - extensible. Repository organization SHALL favor semantic clarity over implementation convenience. --- # 3. Canonical Repository Structure Recommended top-level structure: ``` Repository/ ├── README.md ├── LICENSE ├── CHANGELOG.md ├── archive/ ├── 00-foundation/ ├── 01-constitution/ ├── 02-architecture/ ├── 03-federation/ ├── 04-core-concepts/ ├── 05-reference-architecture/ ├── 06-domain-models/ ├── 07-guides/ ├── examples/ └── schemas/ (optional) ``` Additional directories MAY be introduced provided they do not change the semantic meaning of the repository. --- # 4. Folder Responsibilities **archive/** Contains historical versions retained for traceability. **00-foundation/** Vision, principles, terminology and glossary. **01-constitution/** Normative constitutional documents. **02-architecture/** Architecture standards (MMAS). **03-federation/** Federation protocol specifications (MUFP). **04-core-concepts/** Foundational semantic concepts. **05-reference-architecture/** Reference architectures and architectural patterns. **06-domain-models/** Reusable domain Meta-Models. **07-guides/** Informative implementation and migration guidance. **examples/** Illustrative examples demonstrating correct application of the standards. --- # 5. Document Requirements Every normative document SHOULD define: - document identifier; - title; - version; - status; - classification; - purpose; - final statement. Documents SHOULD remain independently understandable. --- # 6. Naming Conventions Repository naming SHOULD follow MMAS Naming Conventions. Files SHOULD: - use descriptive names; - avoid ambiguity; - remain stable across versions. Normative filenames SHOULD NOT include version numbers. --- # 7. Versioning Repository evolution SHALL follow semantic versioning. Historical releases SHOULD remain available. Breaking structural changes SHALL accompany a new major version. --- # 8. Traceability Repository artifacts SHALL preserve: - provenance; - authorship; - version history; - document lineage; - related standards. Traceability SHALL extend across repository history. --- # 9. Extensibility Repositories MAY include: - schemas; - contracts; - templates; - validation assets; - generated artifacts; - automation resources. Extensions SHALL remain semantically compatible with the reference structure. --- # 10. Validation A conforming repository SHOULD validate: - required folders; - required metadata; - document identifiers; - naming consistency; - version consistency; - cross-document references. Validation SHOULD be automatable. --- # 11. Governance Every repository SHALL identify: - governing authority; - publication process; - supported standard versions; - conformance level. Governance SHALL remain transparent. --- # 12. Architectural Invariants A conforming repository SHALL preserve: - constitutional compliance; - semantic organization; - traceability; - modularity; - long-term maintainability. Repository structure SHALL support semantic evolution without sacrificing historical integrity. --- # Future Directions The Reference Repository describes how a single repository is laid out. The natural next step is a **Meta-Universe Registry Specification** that describes how repositories are *discovered and verified at scale*, forming a Federation of Registries. Such a specification would let AI agents: - auto-discover Meta-Universe repositories from a well-known registry entry point; - detect which MUC, MMAS and MUFP versions each repository supports; - verify conformance (required folders, metadata, identifiers, naming and cross-references) automatically; - and, on that basis, build federation between repositories without manual configuration. Where the Reference Repository makes a single published model recognizable, the Registry Specification would make the *whole ecosystem of models* navigable — the difference between a single published API and an index of all published APIs an agent can query, validate and connect to on its own. --- # Final Statement The Reference Repository defines the canonical organization for Meta-Universe standards and Meta-Models. By adopting a common repository structure, publishers enable humans and AI agents to discover, understand, validate and evolve semantic knowledge consistently across independent repositories while preserving governance, traceability and interoperability throughout the Meta-Universe ecosystem.
