This repository provides the materials developed for the Ontology Governance Framework (OGF), a conceptual and practical approach for defining, organising, and assessing governance practices in ontology projects.
The framework is intended to support ontology developers, maintainers, project teams, and organisations in making governance decisions explicit. It provides reusable structures and resources to help define how ontologies are designed, documented, maintained, shared, reviewed, and evolved over time.
The framework is composed of four main components:
Together, these components support the definition of governance models adapted to the needs, maturity level, organisational context, and available resources of each ontology project.
Governance mechanisms represent the set of Principles, Requirements, and Guidelines that guide decision-making throughout the ontology lifecycle.
These mechanisms help define what should be considered when designing, publishing, maintaining, and reusing an ontology. They address aspects such as:
The governance mechanisms are designed to be adaptable. They can be selected, refined, or extended depending on the objectives, constraints, and governance maturity of a specific ontology project.
The Ontology Lifecycle represents the temporal dimension of the framework. It describes the phases, activities, and tasks involved in the development, publication, use, maintenance, and evolution of an ontology.
The lifecycle provides a structured view of how ontology-related activities are organised over time. It can be adapted to different ontology engineering methodologies and project contexts.
The lifecycle includes phases such as:
This component helps project teams identify when specific governance decisions should be made and how they relate to the different stages of ontology development and management.
This component defines the actors involved in ontology governance and their associated responsibilities.
It helps clarify who is responsible for making decisions, performing tasks, reviewing outputs, maintaining resources, and supporting communication among stakeholders.
Examples of roles include:
The definition of roles and responsibilities supports coordination within ontology projects, reduces ambiguity, and facilitates long-term maintenance. It can also be combined with responsibility assignment models such as RACI matrices.
This repository includes a set of materials that support the application and adaptation of the Ontology Governance Framework.
The framework/ folder contains the core components of the Ontology Governance Framework:
These materials provide the conceptual basis for defining and adapting ontology governance models in different contexts.
The methodology/ folder contains the methodological resources used to support the development, application, and evaluation of the framework.
These materials may include the supporting documentation and other resources used to collect information, analyse governance initiatives and harmonized them.
The repository includes documentation for two anonymised case studies in which the framework has been applied:
Each case study includes materials produced or adapted during the application of the Ontology Governance Framework, such as:
