ToIP Governance Metamodel Specification
This is the home page for the ToIP Governance Metamodel Specification. Please see the Governance Metamodel Companion Guide for a "user's guide" to this specification. The purpose of this ToIP specification is to provide an overall template for ToIP-compatible governance frameworks from which layer-specific templates are derived. Each layer-specific template MUST comply with this specification. They SHOULD add details such as:
- Layer-specific ToIP roles.
- Layer-specific ToIP processes in which actors in those roles are engaged.
- Layer-specific risks against which a risk assessment should be performed (see the Risk Assessment Worksheet Template).
- Layer-specific elements of a trust assurance framework to address those risks (see the Trust Assurance and Certification Controlled Document Template).
Notation and Keywords
All terms appearing in bold on this page are listed in either the ToIP Core Glossary (based on the ToIP Core terms wiki) or the ToIP Governance Glossary (based on the GSWG terms wiki.) For more information see the Terms Wiki page of the Concepts and Terminology WG.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
Primary Document
The primary document is the "home page" for the governance framework (GF). It:
- MUST have a DID (decentralized identifier) that serves as an identifier of the entire GF.
- MUST have a unique DID URL (as defined in the W3C Decentralized Identifiers 1.0 specification) to identify each specific version of the primary document.
- MUST contain authoritative references to all other documents included in the GF, called controlled documents.
Introduction
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:
- SHOULD reference any external websites, white papers, or other helpful background materials.
- SHOULD reference the ToIP Foundation, the ToIP stack, and the specific version of the ToIP governance template upon which the GF is based (if any).
- MAY include an "Acknowledgements" section citing contributors to the GF.
Terminology and Notation
This section asserts the terminology conventions used in the GF. It:
- MUST explicitly specify the use of the ToIP Governance Requirements Glossary (see below).
- MUST reference the GF Glossary controlled document for all other terms (see the Controlled Documents section).
- MAY specify that terms specific to one controlled document are defined in that controlled document.
- MUST specify that all RFC 2119 keywords used with their RFC 2119 meanings are CAPITALIZED.
- SHOULD specify any other formatting, layout, or notation conventions used in the primary document and/or controlled documents.
ToIP Governance Requirements Glossary
requirement | In the context of a governance framework (GF), a requirement states a condition that an actor (human or machine) must meet in order to be in conformance. In ToIP-compliant GFs, all requirements MUST be expressed using RFC 2119 keywords. |
mandatory | A requirement expressed using one of the following RFC 2119 keywords: "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT". |
recommendation | A requirement expressed using one of the following RFC 2119 keywords: "SHOULD", "SHOULD NOT", "RECOMMENDED". |
option | A requirement expressed using one of the following RFC 2119 keywords: "MAY", "OPTIONAL". |
human-auditable requirement | A requirement expressed in a human language that can only be fulfilled by a human actor performing a set of processes and practices against which conformance can only be tested by an auditor of some kind. In a ToIP-compliant governance framework, human-auditable requirements are expressed as policies. |
machine-testable requirement | A requirement written in a machine-readable format such that conformance of a software actor implementing the requirement can be tested by an automated test suite or rules engine. In a ToIP-compliant governance framework, machine-readable requirements are expressed as rules in a rules-based language. |
policy | A human-auditable requirement that specifies some set of processes and practices that an actor must follow in order to be in conformance with the requirement. |
process | A specified set of actions that an actor must take in order to be in conformance with a policy. A process may consist of a set of practices. |
practice | A specified activity that an actor must perform as part of a process. |
rule | A machine-testable requirement written in a machine-readable language that can be processed by a rules engine. |
specification | A document or set of documents containing any combination of human-auditable requirements and machine-testable requirements needed to produce interoperability amongst implementers. Specifications may be included in (as controlled documents) or referenced from a governance framework. |

Purpose
This is a short, clear statement of the overall purpose ("mission") of the GF. It:
- SHOULD be as short and concise as possible—ideally one sentence, or at most one paragraph.
Scope
This is a statement of what is in and out of scope for the GF. It:

- MUST only contain outcomes over which the GF has the authority and mechanisms to achieve within its scope.
- MUST be consistent with the principles of the GF (below).
Principles
This section states the principles by which all members of the trust community agree to abide. It:

Controlled Documents
Each controlled document covers a specific area of the GF. The following sections are categories of controlled documents where each category MAY contain more than one document. Most (but not all) categories are OPTIONAL.
Glossary
This category provides a common basis for terminology. It:
