Open Government Licence
The Open Government Licence is the United Kingdom's standard legal instrument for releasing public sector information for reuse. Administered by The National Archives, it grants a worldwide, royalty-free, perpetual right to copy, adapt and commercially exploit licensed data, subject only to attribution. It is the mechanism through which UK government property, mapping and addressing data becomes reachable without a contract.

Implemented by these standards
A regulation is the law; a standard is the machine-readable contract that satisfies it. Almost every regime in this catalog restricts an interface rather than requiring one — where a standard exists, it is the part a provider can actually publish.
