# Glossary **Meta-Universe Specification** **Document ID:** MU-V2-FOUND-004 **Title:** Human-readable Glossary **Document Class:** Informative **Version:** 2.0 (Draft) **Status:** Working Draft **Normative References:** None **Informative References:** Terminology.md, Definitions.md, Vision.md, Principles.md **Copyright:** © Orkestron.AI **License:** Apache-2.0 --- # 1. Purpose This glossary provides plain-language explanations of the concepts used throughout the Meta-Universe standards. Unlike **Terminology.md**, which contains normative definitions, this document explains ideas through intuition, examples and practical guidance. It is intended for architects, developers, domain experts, students and AI practitioners. --- # 1a. Position Among the Vocabulary Documents The Glossary is the **human-oriented encyclopedia** of the Meta-Universe. It is informative: it builds intuition, gives examples and frames concepts for newcomers. It is deliberately distinct from its two siblings: - **Terminology.md** is the **normative dictionary**. It fixes the official, short meaning of each term and is the authority that other specifications cite. When precision matters, Terminology decides. - **Definitions.md** is the **constitutional interpretation**. It states how selected terms are read when applying the Meta-Universe Constitution (MUC), and it governs governance, conformance and dispute resolution. This Glossary explains; it never overrides. Where this document and a normative document appear to differ, the normative document prevails. --- # 2. How to Use This Glossary When reading the specifications: - Use **Terminology.md** to determine the official meaning of a term. - Use this glossary to understand the concept behind that term. - Use **Definitions.md** when the question concerns constitutional interpretation. - Use the Core Concepts documents for the complete architectural model. --- # 3. Core Concepts ## Universe Think of a Universe as an independent semantic ecosystem. An enterprise, a government, a person, an AI platform or even a digital twin may own its own Universe. Every Universe governs its own knowledge. --- ## Dimension A Dimension is a large semantic space inside a Universe. It separates different knowledge domains without creating separate Universes. --- ## Namespace A Namespace groups related concepts. For example: - employee - organization - product - finance In Meta-Universe v2 the Namespace replaces the former Galaxy concept. --- ## Meta-Object A Meta-Object is the digital semantic identity of something that exists (or is meaningful). Examples include: - Employee - Company - Product - Invoice - AI Agent A Meta-Object represents meaning rather than storage. --- ## Projection A Projection is a view of a Meta-Object. Different audiences receive different Projections of the same object. Example: The HR department, Payroll system and an external partner may all see different information about the same employee. --- ## Context Context explains *why* knowledge is being used. The same information may have different meanings depending on: - purpose; - audience; - time; - assumptions. Without Context, semantic interpretation becomes unreliable. --- ## Event An Event records something that happened. Examples: - Employee hired - Product released - Contract approved Events explain how knowledge evolved. --- ## Relationship Relationships connect Meta-Objects. Examples: Employee reportsTo Manager. Product belongsTo Catalog. Relationships express business meaning. --- ## Canonical Identity The permanent identity of a Meta-Object. Even if local systems change identifiers, the Canonical Identity remains stable. --- ## Identity Binding Identity Binding connects local identifiers to one Canonical Identity. This allows independent systems to recognize the same real-world object. --- ## Semantic Contract A Semantic Contract defines the rules for exchanging knowledge. It specifies: - purpose; - permissions; - responsibilities; - disclosure conditions. --- ## Semantic Mapping A Semantic Mapping explains how concepts from different Meta-Models correspond. It allows independently designed models to work together. --- ## Federation Federation allows independent Universes to collaborate while remaining autonomous. Knowledge is shared without surrendering ownership. --- ## Semantic Sovereignty Every Universe owns and governs its own knowledge. Participation in federation never transfers ownership. --- ## Provenance Provenance answers: "Where did this knowledge come from?" Knowing the origin of information increases trust. --- ## Traceability Traceability answers: "How did we get here?" Every important change can be reconstructed through history. --- ## Governance Governance defines who makes decisions and how standards evolve. It ensures predictable long-term development. --- ## Compatibility Compatibility describes whether two semantic artifacts can work together. Compatibility is explicit rather than assumed. --- ## Certification Certification is independent evidence that something conforms to Meta-Universe standards. Certification builds trust without changing ownership. --- ## AI Agent An AI Agent is more than an LLM. Within the Meta-Universe, an AI Agent reasons using: - Meta-Models; - Context; - Contracts; - Projections; - Events. Knowledge exists outside the language model, making decisions more explainable and reusable. --- # 4. Common Misconceptions **A Meta-Model is not a database schema.** It describes meaning, not storage. **A Projection is not a copy of data.** It is a purpose-specific representation. **Federation is not data replication.** It is governed semantic collaboration. **Trust is not authentication.** Trust also includes governance, purpose and contractual obligations. --- # 5. Learning Path For readers new to Meta-Universe: 1. Read Vision. 2. Read Principles. 3. Read Terminology. 4. Read this Glossary. 5. Read the Constitution. 6. Continue with Core Concepts. The recommended progression is therefore **Vision → Principles → Terminology → Glossary → Constitution**: the Vision sets intent, the Principles set values, Terminology fixes the official meanings, this Glossary makes those meanings intuitive, and the Constitution makes them binding. --- # Final Statement The Glossary bridges the gap between formal specifications and practical understanding. By explaining the concepts behind the Meta-Universe in clear, human-readable language, it helps architects, developers, domain experts and AI practitioners build a shared mental model before exploring the normative standards that define the ecosystem.
