๐ Meta-Universe
Open Standards for Federated Semantic Systems
A common semantic foundation for AI, organizations, software, devices and digital ecosystems โ
so that independent universes of meaning can understand one another without giving up their sovereignty.

## Why Meta-Universe?
Every organization builds its own models.
Every AI system creates its own context.
Every product invents its own ontology.
Today we integrate **data**. Tomorrow we must federate **meaning**.
**Meta-Universe** is an open *family of standards* that lets independent semantic universes exchange knowledge while preserving **Identity, Context, Ownership, Trust, Traceability and Autonomy**.
It is **not** another ontology, database or platform. It is the **constitutional, architectural and federation layer** *above* existing semantic standards.
Why aren't existing tools enough?
| Approach | What it gives | What it misses |
|----------|---------------|----------------|
| **Graph DB** | flexible storage of nodes & edges | no sovereignty, no contracts, no projection of meaning |
| **Ontology (RDF/OWL)** | shared vocabularies | no federation lifecycle, trust model or disclosure control |
| **API (REST/GraphQL/gRPC)** | data transport | answers *how to transfer data*, not *how to agree on meaning* |
| **MDM / Data Catalog** | a single source of record | centralization; one owner of truth |
Meta-Universe answers a different question: **how can two sovereign universes safely agree on a shared understanding of knowledge?**

Each layer depends only on the layers below it. Lower layers never depend on higher ones.

## Core Ideas
| Principle | In one line |
|-----------|-------------|
| ๐ **Reality First** | Models describe reality rather than replace it. |
| ๐ **Universal Identity** | Every Meta-Object has one stable, global identity. |
| ๐ช **Projection** | Each universe sees its own context-specific projection โ never the raw object. |
| ๐ **Federation** | Universes exchange projections, not ownership. |
| ๐ค **Knowledge Contracts** | Knowledge is disclosed through explicit, purpose-bound contracts. |
| ๐ก๏ธ **Trust** | Trust is established, never assumed โ and never confused with security. |
| ๐ **Traceability** | Every significant fact can be traced to its origin and its lineage. |
| ๐ **Semantic Interoperability** | Schemas are shared before data is exchanged. |
See the full [Manifesto](00-foundation/Vision.md#the-meta-universe-manifesto) and the seventeen [Principles](00-foundation/Principles.md).

## Standards Family
| Standard | Purpose | Status |
|----------|---------|--------|
| **MUC** โ [Meta-Universe Constitution](01-constitution/Meta-Universe-Constitution.md) | The fundamental laws and invariants (21 articles, 6 chapters) | ๐ง Working Draft |
| **MMAS** โ [Meta-Model Architecture Standard](02-architecture/MMAS-Core.md) | How to build, version, validate and package a meta-model | ๐ง Working Draft |
| **MUFP** โ [Meta-Universe Federation Protocol](03-federation/MUFP.md) | How sovereign universes discover, trust and exchange knowledge | ๐ง Working Draft |
| **Core Concepts** โ [04-core-concepts](04-core-concepts/) | The shared semantic vocabulary (Object, Relationship, Event, Contract, Projection, โฆ) | ๐ง Working Draft |

## The Five Semantic Primitives
```mermaid
flowchart LR
O["Object
what exists"]
R["Relationship
how it connects"]
E["Event
how it changes"]
C["Contract
on what terms"]
P["Projection
how it appears"]
O --- R --- E --- C --- P
```
A single **Meta-Object** (a *Semantic Point of Truth*) is connected by **Relationships**, evolves through **Events**, is governed by **Contracts**, and is seen through context-specific **Projections** โ all interpreted within a **Context**.

## Repository Map
The repository is organized **by semantics, not by file type** โ each folder answers a question.

02-architecture/ How meta-models are built (MMAS, Versioning, Validation, Packaging, ...)
03-federation/ How universes interact (MUFP, Trust, Identity Binding, Mapping, ...)

## Relationship with Existing Standards
Meta-Universe **unifies** rather than **replaces**. It is a layer that lets these standards coexist and federate.
| Existing standard | Meta-Universe relationship |
|-------------------|----------------------------|
| OData | imported & projected as business entities |
| RDF / OWL | imported as semantic graphs; federated, not centralized |
| Schema.org | imported as public web vocabulary |
| OpenAPI | described as a projection / service contract |
| BPMN | imported as process semantics |
| FHIR | imported as a domain (healthcare) meta-model |
| ArchiMate | imported as enterprise-architecture semantics |
External standards are imported as versioned **[Semantic Packages](02-architecture/Extension-Model.md)**, aligned through **[Semantic Mappings](03-federation/Semantic-Mapping.md)**, and composed via **[Meta-Model Composition](02-architecture/Meta-Model-Composition.md)** โ the rule for when a concept is a field, a nested model, or a reference โ using the **[Connector Catalogue](06-ecosystem/Connector-Catalogue.md)** as the shared set of joints between the **[1180 catalogued standards](06-ecosystem/External-Models-Registry.md)**.
---
## Roadmap
| Version | Theme |
|---------|-------|
| **v1.0 / v1.1** | First conceptual model (Universe โ Dimension โ Galaxy โ Object โ Projection) |
| **v2.0 (current)** | Full standards family: MUC + MMAS + MUFP + Core Concepts + Reference Architecture + Ecosystem + Guides |
| **Future** | Candidate standards โ SVF, MMQS, SMS, MUDL, Semantic Package Registry; reference meta-models; tooling & SDKs |
See the detailed [Roadmap](06-ecosystem/Roadmap.md) and the consolidated *Candidate Future Standards*.
---
## Ecosystem
Meta-Universe is designed as a **family of repositories**:
| Repository | Purpose |
|------------|---------|
| **Meta-Universe** (this repo) | The ISO-like open standard: MUC, MMAS, MUFP, Core Concepts |
| **meta-universe-reference-models** *(planned)* | Full reference meta-models (Employee, Organization, Product, AI Agent, โฆ) |
| [software-meta-model](https://github.com/orkestron-ai/software-meta-model) | A domain meta-model built on these standards |
| [product-landscape-meta-model](https://github.com/orkestron-ai/product-landscape-meta-model) | The federation layer above AISMM: a whole product landscape as one model |
| [meta-orchestrator-state](https://github.com/orkestron-ai/meta-orchestrator-state) | A polity modelled as one Dimension (Axiacracy / MOS): the largest known application |
| software-agents-contracts | Contract โ Protocol โ Deliverable specification for AI agents |
Compatible domain meta-models include AISMM, the Employee Meta-Model, the Enterprise Landscape Meta-Model and the Product Landscape Meta-Model.
Two in-depth case studies document how these concepts behave in real systems: [The Orkestron Ecosystem](06-ecosystem/Case-Study-Orkestron-Ecosystem.md) (a production ecosystem of meta-models and federated projections) and [Axiacracy / Meta-Orchestrator State](06-ecosystem/Case-Study-Axiacracy-MOS.md) (a whole state as a large meta-universe).

## Freeze Rule
1. Documents are created in dependency order.
2. Approved documents become **Frozen**.
3. Frozen documents change only through an explicit [Change Request](01-constitution/Change-Process.md).
4. Later documents build on Frozen documents.

## Contributing
Meta-Universe is an open specification. Contributions, reviews and proposals are welcome โ start with **[CONTRIBUTING.md](CONTRIBUTING.md)**, the project **[GOVERNANCE.md](GOVERNANCE.md)**, the **[Code of Conduct](CODE_OF_CONDUCT.md)** and the **[Security Policy](SECURITY.md)**. Changes flow through the [Change Process](01-constitution/Change-Process.md); please read the [Principles](00-foundation/Principles.md) and the [Constitution](01-constitution/Meta-Universe-Constitution.md) first โ every contribution must remain consistent with both.
Implementers: the **[Core Profile](02-architecture/Core-Profile.md)** defines the minimal mandatory subset to be "Meta-Universe Core conformant".
