+## Verifiable Credential
+
+> **IRI**: [credential-governance-declaration:GovernanceDeclarationCredential](https://w3id.org/axone/ontology/v4/schema/credential/governance/declaration/GovernanceDeclarationCredential)
+
+### Description
+
+The Governance Declaration Credential represents a specialized subclass of Verifiable Credentials designed to define and formalize
+the Governance framework applicable to a specific Resource. This credential is pivotal in decentralized systems and ensures explicit,
+verifiable governance alignment across a variety of resource types.
+
+#### Scope and applicability
+
+- *Zone Governance*: Territorial in nature, this governance establishes a domain of sovereignty and jurisdiction where various
+  resources—such as datasets, services, and individuals—recognized by the governance framework can operate or coexist within its boundaries. It defines the legal and regulatory environment applicable to the governed entities.
+- *Dataset or Service Governance*: Contractual in nature, this governance defines the terms and conditions for accessing and using the
+  resource. For example, it may specify that access to a dataset is restricted to services that present specific verifiable claims demonstrating
+  compliance with particular requirements, such as legal or operational standards.
+
+#### Self-determination and authority transfer
+
+The VC *must* be issued by the resource itself, adhering to the principle of self-determination. This ensures that the resource and the
+credential issuer share a unified identity. Upon issuance, the credential executes a constitutional transfer of authority from the resource
+to an autonomous, decentralized governance system directly associated with it. This governance system operates independently, utilizing
+its own mechanisms to self-regulate and manage modifications or revisions of the governance framework in a decentralized and deterministic manner.
+
+#### Governance reference
+
+The governance declaration is characterized by a URI reference that uniquely identifies an immutable governance definition. These URIs are
+required to be:
+
+- **Unique**: Each URI must represent a distinct governance definition.
+- **Immutable**: The governance definition associated with the URI must remain unchanged over time.
+- **Dereferenceable**: The governance content must be retrievable by resolving the URI, ensuring transparency and accessibility.
+
+### Properties
+
+#### Is governed by

+> **IRI**: [credential-governance-declaration:isGovernedBy](https://w3id.org/axone/ontology/v4/schema/credential/governance/declaration/isGovernedBy)
+>
+> **Domain**: [credential-governance-declaration:GovernanceDeclarationCredential](https://w3id.org/axone/ontology/v4/schema/credential/governance/declaration/GovernanceDeclarationCredential)
+>
+> **Range**: [xsd:anyURI](http://www.w3.org/2001/XMLSchema#anyURI)
+
+The governance that a resource is governed by.
+
+This property links a resource to the governance that applies to it. Governance is represented by a URI that uniquely identifies the governance definition.
+The URI must be dereferenceable, meaning it should allow retrieval of the governance definition when accessed.
+
+**Example**:
+
+```txt
+# Reference to governance stored in the Law-Stone smart contract at a specific address
+contract:law-stone:axone1hndfmswue3x47meah8sat4fpvj4rvfha4d7ugr849ay4rw7nnxlqcyxlhv
+```
+
+#### Constraints
+
+- Governance URIs must be:
+  - **Unique**: Each URI must uniquely identify a governance definition.
+  - **Immutable**: The governance definition it points to should not change over time.
+  - **Dereferenceable**: It must be possible to retrieve the governance data using the URI.
+- Governances must originate from a Governance as Code approach, ensuring they are interpretable and executable deterministically by an existing smart contracts.
+
+#### Note
+
+In the Axone protocol, governances are defined using the Prolog language and hosted in dedicated smart contracts. However, a Verifiable Credential (VC)
+can reference any governance definition, as long as it adheres to the above constraints.
