CoST Datastore and Registry

Access infrastructure project data in OC4IDS format

Welcome to the CoST Datastore and Registry. The datastore provides access to datasets published by CoST members according to the Open Contracting for Infrastructure Data Standard (OC4IDS). The datasets are valid according to the OC4IDS schema and openly licensed. You can download full datasets in spreadsheet, CSV or JSON format, ready for analysis in your preferred tool.

The datastore fetches and stores data from OC4IDS publishers on a daily basis. If a publisher's data fails validation against the OC4IDS schema or is unavailable, the datastore provides access to the most recent valid dataset successfully fetched from the publisher.
