“The Open Contracting Data Standard (OCDS), is a free, non-proprietary open data standard for public contracting, implemented by over 30 governments around the world. It is the only international open standard for the publication of information related to the planning, procurement, and implementation of public contracts and has been endorsed by the G20, the G7 and major international organizations. The OCDS describes how to publish data and documents at all stages of the contracting process. It was created to support organizations to increase contracting transparency and enable deeper analysis of contracting data by a wide range of users. The OCDS provides:

• A set of recommended data fields and documents to publish;
• A common structured data model;
• Guidance and tools to support implementation and data use;
• Profiles for Public Private Partnerships, Infrastructure Projects, the European Union, and the World Trade Organization’s Agreement on Government Procurement;
• Toolkits such as the Open Contracting for Infrastructure Data Standard (OC4IDS) to connect contracts to project-level information and publish standardized data on infrastructure projects;
• An extension mechanism to add additional key information to your OCDS data; and
• A free data support team.”
