Open Contracting Data Standard
An early version 1.0 was released in July 2015  and version 1.1 is being developed in Q 3 and 4 2015. OCDS was designed with a focus on public procurement of goods, works and services, but can be extended for use in other contexts. Extensions for Public Private Partnership (PPP) and Extractives concessions are under development.
Adoption of the standard requires publishers to release data under an open license. Publishers are encouraged to use a scale of publishing complexity, from basic which features just tender notices, to advanced and extended data, which features contract award notices, contract details and persistent URIs.
Pilot implementations are underway in the following countries:
- United Kingdom - see UK Open Government National Action Plan 2016-18 
- Ukraine - public e-procurement system Prozorro
