This site describes how to combine contract level disclosures using the Open Contracting Data Standard (OCDS) with project-level disclosure based on the CoST Infrastructure Data Standard (CoST IDS), in order to support scalable disclosure and monitoring of infrastructure project identification, preparation, implementation and delivery.

This Open Contracting for Infrastructure Data Standards (OC4IDS) Toolkit will show you how to:

• Publish standardized data on infrastructure projects and contracts using the CoST IDS and OCDS.
• Extract infrastructure contracting data from existing procurement portals.
• Connect contract and project-level information using OC4IDS.
• Assess published data against the CoST IDS.
• Make use of data when monitoring infrastructure projects.
