Implementing the
Open Contracting Data Standard

We have developed detailed documentation to guide you in implementing the Open Contracting Data Standard, and many technical blogs, templates, and other guidance material.

The Open Contracting Data Standard documentation is your key resource to implementing the standard. It provides you with access to the latest version of the data specification, guidance on data publication, documentation of extensions, and other relevant resources.

We also have step-by-step guidance, including helpful templates and tools to support your OCDS implementation here.

Most importantly, our free helpdesk is ready to help. Just reach out to us with any questions at

Why implement the Open Contracting Data Standard

Contracting data published in an OCDS format is easier to share, compare and analyze. It allows publishers to adapt and reuse existing visualization and analysis tools like these, reducing costs and promoting innovation. The OCDS provides guidance on what to publish and how to publish the most important details about public contracting as identified by practitioners, researchers and other stakeholders.

The OCDS was crafted for four specific user needs, underpinned by a field-by-field analysis of how the data can be used to support those needs. They are:

  • Delivering better value for money, saving government money and time;
  • Building a fairer business environment and a level playing field for suppliers; and
  • Improving public integrity by deterring fraud and corruption; and
  • Tracking and improving service delivery.

Embedded into wider reforms, governments can use open contracting to secure better value for money for goods, works, and services and to build the trust of the private sector, civil society and citizens.
