Schema Reference

The Open Contracting Data Standard is maintained using JSON Schema.

The main sections and common objects used in the schema are introduced in the getting started section.

In this section you will find the full JSON schema along with the release package and record package schemas which act as envelopes when publishing using OCDS.

The release schema reference page provides guidance on using each of the sections and building blocks in the schema, and the record schema reference provides additional information on publishing compiled and versioned records.
