Open Contracting Data Standard: Documentation¶
Governments around the world spend an estimated US$9.5 trillion through contracts every year. Yet, contracting information is often unavailable for public scrutiny.
The Open Contracting Data Standard (OCDS) enables disclosure of data and documents at all stages of the contracting process by defining a common data model. It was created to support organizations to increase contracting transparency, and allow deeper analysis of contracting data by a wide range of users.
The OCDS approach:
- Publish early, and iterate: improving disclosure step-by-step
- Simple and extensible JSON structure
- Publish data for each step of the contracting process
- Create summary records for an overall contracting process
- Re-usable objects: organizations, tender information, line-items, amounts, milestones, documents etc.
- Recommended data and documents at basic, intermediate & advanced levels
- Common open data publication patterns
- Guidance on improving data collection and data quality
- A growing community of users and range of open source tools
This is the 1.1 release of OCDS, published on 31st May 2017. Version 1.0 documentation is still available from the version switcher at the bottom left of the page.
The Open Contracting Data Standard is a core product of the Open Contracting Partnership (OCP).
Version 1.0 of the standard was developed for the OCP by the World Wide Web Foundation, through a project supported by the Omidyar Network and the World Bank. Ongoing development is managed by Open Data Services Co-operative under contract to OCP.
