AIGO — Terminology

1. Document Purpose

This document establishes the controlled terminology for the AIGO Framework. Its purpose is to provide a consistent vocabulary across:
  • the AIGO framework;
  • governance domains;
  • roles;
  • lifecycle;
  • risk management;
  • controls;
  • maturity;
  • system profiles;
  • implementation guidance;
  • procedures;
  • templates;
  • examples;
  • schemas;
  • mappings;
  • validation tools;
  • evidence;
  • assurance.
Where a term is defined here, that definition should be used consistently throughout the AIGO repository unless a source framework requires a distinct framework-specific meaning.

2. Document Information


3. Terminology Principles

AIGO terminology follows these principles:
  1. Terms should have one stable meaning within the AIGO framework.
  2. Definitions should be operationally usable.
  3. Source-framework terms must retain their original meaning when used in framework mappings.
  4. AIGO internal terms must not be presented as legal definitions unless they are directly supported by applicable law.
  5. Similar terms must not be treated as identical merely because they overlap conceptually.
  6. Framework-specific terminology should be explicitly qualified where ambiguity is possible.
  7. Machine-readable identifiers should map to controlled terminology where appropriate.

4. AIGO

Definition AIGO is the AI Governance Operating Framework, a structured framework for establishing, operating, monitoring, assuring, and continually improving governance over artificial intelligence systems, AI-related risks, controls, evidence, and decisions. Usage Use AIGO when referring to the complete framework.

5. AI Governance

Definition AI governance is the system of leadership, accountability, decision rights, policies, processes, controls, oversight, monitoring, assurance, and improvement through which an organization directs and controls its AI activities. Usage AI governance describes the organizational governance system rather than a single control or procedure.

6. AI System

Definition An AI system is an identifiable technological system within the organization’s governance scope that performs or supports AI-related functions and is subject to AIGO governance. Usage The precise legal or regulatory definition of an AI system may differ between source frameworks and jurisdictions. AIGO therefore uses this as an internal governance term. Related Terms
  • AI system profile
  • AI system lifecycle
  • AI system owner
  • AI classification

7. AI Model

Definition An AI model is a computational model used by an AI system to generate outputs, predictions, classifications, recommendations, content, decisions, or other results. Usage An AI model may be one component of a larger AI system.

8. AI Service

Definition An AI service is an AI-enabled capability delivered to users, applications, organizations, or other systems. Usage An AI service may contain one or more AI systems, models, data sources, interfaces, or supporting components.

9. AI Lifecycle

Definition The AI lifecycle is the sequence of governance-relevant stages through which an AI system is planned, designed, developed or acquired, evaluated, approved, deployed, operated, monitored, changed, improved, and retired. AIGO Lifecycle

10. AI Risk

Definition AI risk is the possibility that an AI-related event, condition, decision, system behavior, or failure may result in undesirable consequences for people, organizations, assets, operations, society, or the environment.

11. AI Impact

Definition AI impact is an actual or potential consequence of an AI system, AI-related decision, or AI activity affecting people, groups, organizations, society, the environment, or other relevant stakeholders. Usage Impact may be positive, negative, intended, unintended, direct, indirect, short-term, or long-term.

12. AI Governance Objective

Definition An AI governance objective is a defined governance outcome that AIGO seeks to establish, maintain, monitor, or improve. Example

Usage The exact legal meaning and applicability of AI literacy may vary by source framework.

41. Transparency

Definition Transparency is the provision of appropriate information about an AI system, its purpose, operation, limitations, relevant risks, or consequences to the people or organizations who require that information. Usage Framework-specific transparency obligations remain authoritative within their source mappings.

44. Accountability

Definition Accountability is the assignment and acceptance of responsibility for decisions, actions, outcomes, and governance obligations.

45. Responsibility

Definition Responsibility is the duty or obligation assigned to a person, role, or organizational unit to perform or oversee a defined activity. Distinction Responsibility describes the assigned duty. Accountability describes answerability for the resulting outcome.

46. AI Classification

Definition AI classification is the structured determination of an AI system’s category, status, or governance treatment according to defined criteria. Critical Rule An AIGO internal classification must not automatically be represented as a statutory or regulatory classification.

47. Legal Classification

Definition A legal classification is a classification established by applicable law or regulation. Example An EU AI Act legal classification is distinct from an organization’s internal risk rating.

48. Internal Risk Classification

70. Assurance Gap

Definition An assurance gap exists when an applicable control or requirement lacks appropriate assurance coverage where such coverage is required or established by the AIGO assurance model.

71. Traceability Gap

Definition A traceability gap exists when a required relationship between governance objects cannot be established or resolved.

72. Version Gap

Definition A version gap exists when a source framework, mapping, control, evidence, assurance activity, or related governance artifact references an incompatible, obsolete, or unidentified version.

73. Harmonization Gap

Definition A harmonization gap exists when materially similar operational requirements are implemented separately without an identified reason or when an opportunity for defensible common implementation has not been addressed.

74. False Equivalence

Definition False equivalence is the incorrect assumption that two requirements, standards, laws, controls, outcomes, or assurance conclusions are equivalent merely because they address related subject matter. AIGO Rule

116. Certification Readiness

Definition Certification readiness is the documented state in which an organization has prepared for an external certification assessment against a specified certification standard and scope. Certification readiness does not constitute certification.

117. Compliance

Definition Compliance is conformity with an applicable legal, regulatory, contractual, organizational, or other defined requirement. AIGO Boundary AIGO repository validation should not describe a system or organization as legally compliant unless the relevant assessment has actually been performed against applicable criteria.

118. Conformity Assessment

122. External Assessment

Definition An external assessment is an evaluation performed by a party external to the organization according to an established scope, methodology, and criteria.

123. Framework Equivalence

Definition Framework equivalence is a formally justified determination that two framework elements are sufficiently equivalent for a specifically defined purpose. AIGO Rule AIGO does not assume equivalence merely from overlapping subject matter.

124. Operational Harmonization

Definition Operational harmonization is the deliberate use of common governance processes, controls, evidence, or assurance mechanisms to satisfy related requirements across multiple frameworks.

125. Reusable Evidence

Definition Reusable evidence is evidence that can legitimately support more than one governance or framework relationship while remaining traceable and sufficient for each applicable criterion.

126. Shared Evidence

Definition Shared evidence is a single governed evidence record associated with multiple framework or control relationships. Shared evidence must be evaluated independently for sufficiency.

127. Shared Assurance

Definition Shared assurance is an assurance activity that evaluates multiple related framework criteria through common testing or evidence where the scope and methodology are sufficient.

128. Framework-Specific Assurance

Definition Framework-specific assurance is assurance performed against criteria that arise from a specific framework and cannot be safely generalized to other frameworks without additional evaluation.

Definition An AIGO internal requirement is a requirement established by the AIGO framework itself for implementation, governance, validation, documentation, or repository operation.

133. Mandatory

Definition Mandatory describes an obligation that must be satisfied under the authority applicable to the specific context. The source of mandatory status must be identified.

134. Recommended

Definition Recommended describes an AIGO or source-framework practice that is advised but is not itself represented as a binding legal requirement unless the authoritative source states otherwise.

135. Not Applicable

Definition Not applicable is a formally determined state indicating that a requirement, control, evidence expectation, or assurance criterion does not apply within a defined scope.

136. Superseded

Definition Superseded describes an artifact, version, record, requirement, or control that has been replaced by a later approved artifact while remaining relevant for historical traceability.

137. Historical

Definition Historical describes information retained to preserve the state of a system, governance process, framework, evidence set, or decision at an earlier point in time.

138. Current

Definition Current describes the approved version of an artifact or framework relationship applicable to the present governance state.

Definition An evidence baseline is the defined set of evidence expected or required to demonstrate implementation, operation, performance, or assurance of a specified control or requirement.

141. Assurance Baseline

Definition An assurance baseline is the defined set of assurance criteria, scope, methods, and coverage expected for a specified governance scope.

142. Governance Baseline

Definition A governance baseline is the approved set of governance requirements, controls, roles, processes, evidence, and assurance expectations applicable to a defined organizational scope.

143. Terminology Conflict

Definition A terminology conflict exists when the repository uses the same term with materially different meanings in different AIGO artifacts without explicitly identifying the distinction.

144. Controlled Term

Definition A controlled term is a term whose meaning is defined in this document and whose use should remain consistent throughout the AIGO repository.

145. Preferred Usage Rule

Where multiple expressions could describe the same concept, AIGO should use the terminology defined in this document unless:
  • a source framework requires its own terminology;
  • a legal definition must be quoted or preserved;
  • a technical term has a distinct established meaning.
When a source-specific term differs from an AIGO term, the source-specific term should be identified explicitly.

146. Source-Specific Terminology Rule

The following pattern should be used:
Example:

147. Capitalization

The following names should retain their defined capitalization where referring to the formal framework or artifact:
  • AIGO;
  • AI Governance;
  • AI System;
  • EU AI Act;
  • ISO/IEC 42001;
  • NIST AI RMF.
Generic usage may be lowercase where grammatically appropriate.

148. Identifier Rule

Where a controlled object has a machine-readable identifier, documentation should use the identifier consistently. Examples:

149. Definition Hierarchy

Where definitions conflict, apply the following order:
A lower-level document must not silently override a higher-level definition.

150. Framework Mapping Rule

When a source framework uses a term that differs from AIGO terminology:
  1. retain the source term where necessary;
  2. identify the source framework;
  3. preserve the source meaning;
  4. map the source concept to the appropriate AIGO concept;
  5. do not imply equivalence unless justified.

151. Terminology and Schemas

Schema property names should use controlled terminology where practical. For example:
The machine-readable property name should remain stable even if explanatory text evolves.

152. Terminology and Mappings

Mapping documents should distinguish:
These terms should not be collapsed into a generic compliance item.

153. Terminology and Validation

Validation findings should use controlled categories such as:

154. Terminology and Evidence

Evidence should describe what is demonstrated, not merely what document exists. For example:
is an artifact.
describes the governance evidentiary purpose.

155. Terminology and Assurance

Assurance should not be described simply as:
unless that conclusion is specifically within the authorized scope and criteria of the assessment. Preferred terminology includes:
  • effective;
  • partially effective;
  • insufficient evidence;
  • finding identified;
  • readiness demonstrated.

156. Terminology and Compliance Claims

AIGO documents should avoid unsupported statements such as:
unless the statement is explicitly scoped, evidenced, and authorized.

157. Terminology and Legal Claims

AIGO internal terms should not be presented as legal definitions unless the legal source explicitly establishes the definition. Where legal terminology is important, the mapping should identify the source provision.

158. Terminology Review

This terminology document should be reviewed whenever:
  • a new major AIGO concept is introduced;
  • a schema introduces a new controlled object;
  • a framework mapping introduces material terminology conflict;
  • a validation category changes;
  • a v1 or later release changes core architecture.

159. Terminology Change Control

Changes to controlled terminology should be:
  • documented;
  • versioned;
  • reviewed;
  • evaluated for downstream impact.
Material terminology changes should trigger review of:
  • schemas;
  • guidance;
  • procedures;
  • mappings;
  • templates;
  • examples;
  • validators.

160. Backward Compatibility

Where terminology changes, the repository should preserve historical identifiers and references where practical. A terminology change should not silently invalidate existing machine-readable relationships.

161. Terminology Deprecation

A term may be marked:
A deprecated term should identify its preferred replacement.

162. Terminology Registry Principle

The controlled terminology document is the human-readable terminology authority. Future machine-readable terminology registries may be introduced, but should remain synchronized with this document.

163. Minimum Controlled Vocabulary

The following are designated core AIGO terms:

164. Final Terminology Principle

AIGO uses the following governing principle:
Use one controlled AIGO vocabulary for the framework, while preserving source-specific meanings wherever law, standards, or external frameworks define concepts differently.
This prevents terminology drift, reduces ambiguity, supports machine-readable traceability, and allows the framework to integrate multiple external sources without collapsing their distinct meanings.
