Governance
How OPDA is governed, who governs it, the UK government initiative it sits inside, and the published rules that make the standard authoritative. PDTF follows the Trust Over IP four-layer model, with the wider context defined by the Digital Markets, Competition and Consumers Act 2024 and coordinated through the Digital Property Market Steering Group.
