About OC4IDS

The Open Contracting for Infrastructure Data Standard (OC4IDS) describes how to combine contract-level disclosures (using the Open Contracting Data Standard) and project-level disclosures (based on the CoST Infrastructure Data Standard) to support scalable disclosure and monitoring of infrastructure projects.

Trillions of dollars are spent every year on infrastructure and estimates suggest between 10 and 30% of infrastructure investment is lost through inefficiency, mismanagement and corruption. Access to better and more joined up data is essential to drive better quality, more affordable and more accessible infrastructure for government, citizens and business.

Check and review

This tool helps you to:

  • Check that your OC4IDS data complies with the schema
  • Inspect key contents of your data to review data quality
  • Explore your data's coverage of OC4IDS fields to identify possible additions

Using the Data Review Tool

You can upload, paste or provide a link to data published using the Open Contracting for Infrastructure Data Standard. This can be:

  • A JSON file - following the OC4IDS schema;
  • A CSV file or Excel Spreadsheet - using a flattened serialization of OC4IDS;

Supported encodings are UTF-8 for JSON and UTF-8, Windows-1252 and ISO-8859-1 for CSV.

The application works with data provided in an OC4IDS project package.

If your data passes basic structural checks, the tool will then present a report on data quality, and information about the contents of your file.

Data is stored for 7 days at a randomly generated URL. You can share this link with others to support discussion of data quality.
