This page represents the proposed structure of the ToIP Governance Metamodel. The purpose of the metamodel is to provide an overall template for ToIP-compatible governance frameworks from which the GSWG will then develop layer-specific templates. Each layer-specific template will be an instance of the metamodel that adds details such as:

The balance of this page defines the proposed metamodel and the requirements for each component. In these requirements, the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" are to be interpreted as defined in RFC 2119.

All terms appearing in First Letter Caps on this page MUST be added to the ToIP Glossary tagged for inclusion in the ToIP Governance Glossary. (Note: the Concepts and Terminology WG has been briefed on this dependency.) The following terms have specific definitions used in this document:


  • Requirements include any combination of Policies, Rules, and Specifications. Unless otherwise stated, all Requirements MUST be expressed as defined in RFC 2119
  • Machine-Testable Requirements are Requirements with which compliance can be verified using an automated test suite and appropriate scripting or testing software.
  • Human-Auditable Requirements are Requirements with which compliance can only be verified by an audit of people, processes, and procedures.
  • Policies are Human-Readable Requirements. For Policies, the full range of RFC 2119 keywords apply, i.e., "SHOULD", "MAY", and "RECOMMENDED" all have weight from an auditing perspective. An implementer MUST explain why a SHOULD or RECOMMENDED was not implemented and SHOULD explain why a MAY was implemented.
  • Rules are Machine-Readable Requirements that can be processed by a Rules Engine. They are expressed in a structured rules language as specified by the GF.
  • Specifications are documents containing any combination of Machine-Testable Requirements and Human-Auditable Requirements needed to produce technical interoperability.

Primary Document

The Primary Document is the "home page" for the governance framework (GF). It:

  1. MUST have a DID (Decentralized Identifier) that serves as an identifier of the entire GF.
  2. MUST have a unique DID URL (defined in the DID spec) to identify each specific version of the Primary Document.
  3. MUST contain authoritative references to all other documents included in the GF, called the Controlled Documents.
  4. MUST include Policies in the Revisions section stating how the Controlled Documents are governed by the Governance Authority.


This section is a non-normative general introduction to the GF whose purpose is to orient first-time readers as to the overall context of the GF. It:

  1. SHOULD have a reference to the ToIP Foundation, the ToIP Stack, and the specific version of the ToIP Governance Template from which it was derived.
  2. MAY include an Acknowledgements section to acknowledge the contributors to the GF.


This is a short, clear statement of the overall purpose (mission) of the GF. It:

  1. SHOULD be as short and concise as possible—ideally one sentence, or only a few sentences.


This is a statement of what is in and out of scope of the GF. It:

  1. SHOULD clearly state the primary Governed Actors in the Trust Community.
  2. SHOULD state any other relevant stakeholders.

  3. SHOULD state the primary types of interactions or transactions these Governed Actors will be engaging in. 
  4. SHOULD, if applicable, clearly state who and what are out of scope.


This states the high-level outcomes desired by the Trust Community through its adoption of the Governance Framework. It:

  1. SHOULD specify tangible, achievable results (e.g. SMART criteria and Fit-for-purpose criteria).
  2. SHOULD specify the intended overall outcomes to be produced by conformance with the Requirements in the GF.
  3. MUST only contain outcomes over which the GF has the authority and mechanisms to achieve within its Scope.
  4. MUST be consistent with its Principles.


This section states the Principles by which all members of the Trust Community have agreed to abide. It:

  1. SHOULD serve as a guide to the development of any Requirements based on each Principle ("Principles guide Policies").
  2. SHOULD refer to existing Principles—whether defined by other ToIP GFs or by other sources—whenever possible.
  3. SHOULD be referenced (along with any other relevant parts of the GF) in any Legal Agreement between Members and the Governance Authority.
  4. MUST NOT include requirements using RFC 2119 terms for which either human or machine conformance can be directly tested — those should be stated as Requirements elsewhere in the GF.

General Requirements

This section contains Requirements that apply to the GF as a whole and not just in the context of a particular Controlled Document. It:

  1. SHOULD include the Policies that:
    1. Apply generally to governance of the entire Trust Community;
    2. Apply to the structure of the GF, e.g., what Controlled Documents must be specified by whom and applied to whom.
    3. Guide the development of more specific Policies within the Controlled Documents.
  2. SHOULD NOT include Policies that apply only within the context of a specific category addressed by one of the Controlled Documents.
  3. MUST include Responsible Use Policies that apply generally to infrastructure governed by the GF.
  4. MUST include any Regulatory Compliance Policies that are not specified within particular Controlled Documents.


This section contains the specific Policies governing revisions to the GF. It does not include Governance Policies for the Governance Authority or interdependent Governance Authorities (those are defined in Controlled Documents in the Governance category). It:

  1. MUST state the full legal identity and contact information for the primary Governance Authority or interdependent Governance Authorities.
  2. MUST include Policies specifying how any revisions to the GF are identified, developed, reviewed, and approved.
  3. SHOULD include at least one public review period for any GF that will be available to the public.


This section applies to GFs that permit extensions via the incorporation of other GFs (a common feature especially of some ecosystem GFs). It:

  1. MUST state whether the GF can be extended.
  2. MUST specify the requirements an Extension Governance Framework must meet in order to be approved.
  3. MUST specify the process for an Extension Governance Framework to be approved.
  4. MUST define an authoritative mechanism for registration and activation of an approved Extension Governance Framework.
  5. MUST define the requirements for notification of the Trust Community about an approved Extension Governance Framework.

Schedule of Controlled Documents 

This is a listing of all Controlled Documents in the GF. It:

  1. MUST include authoritative references to all Controlled Documents in the GF.
  2. MUST identify the exact version of each Controlled Document with a unique, permanent DID or DID URL.
  3. SHOULD include a Web link to each Controlled Document in the Web version of the GF.
  4. SHOULD include a brief description of the purpose and scope of each Controlled Document to make it easy for readers to navigate the GF.

Controlled Documents

Each Controlled Document covers a specific area of the GF. The following are categories of Controlled Documents where each category MAY include zero or more Controlled Documents.


The Glossary provides a common basis for terminology. It:

  1. SHOULD be a single Controlled Document (even if it is organized by categories or other heuristics).
  2. SHOULD provide a common reference for all possibly ambiguous terms used throughout the GF.
  3. SHOULD reference the ToIP Glossary—or tagged subset(s) of the ToIP Glossary—for all terms defined there.
  4. SHOULD conform to standard requirements for a glossary, i.e., list all terms alphabetically (by language) for easy reference.
  5. MAY tag terms by category or usage.
  6. MAY specify that terms specific to one Controlled Document are defined in that Controlled Document.

Risk Assessment

This category includes links to an ISO 27005 (or compatible) risk assessment for managing risk. Controlled Documents in this category:

  • SHOULD assess which Roles and Processes are vulnerable to each risk and how they are affected.
  • MAY include a Risk Treatment Plan (RTP) for how identified risks are treated (e.g. mitigated, avoided, accepted or transferred); however, all risks that are to be mitigated by directives in the GF SHOULD be identified.

Trust Assurance and Certification

This category specifies Policies for Governed Actors be held accountable against Requirements of the GF. Controlled Documents in this category:
