The Moresburg Model for Trust Frameworks and Schemes provides the comprehensive structure for establishing, evolving, and operating a digital identity system. 

At the national level, this framework includes key policy areas such as Principles, Legislation, Overarching Rules, Trustmark usage, Certification processes, Good Practice Guidance, and a Code of Conduct. 

Governance is a critical component, often involving an independent regulator with statutory powers granted through legislation to ensure participants are legally obligated to follow the rules and to allow for enforcement against "bad actors". 

Beneath the national framework operate Schemes, managed by Scheme Operators through Governance Manuals and specific Procedures. Scheme procedures detail contractual agreements for participants and cover areas like the Commercial Model, Certification, Assurance Framework, Operational Procedures, Liability, Financial Management, Regulatory Compliance, Reporting, and managing Acceptance/Relying Parties. 

The overall model aims to build trust and ensure the reliability and integrity of the digital identity ecosystem through defined roles, rules, accreditation, monitoring, redress, and enforcement.
