Transparency and data disclosure standards
Application
Provide a common disclosure framework for defining, publishing, reviewing, and assessing project and contracting data across the infrastructure lifecycle, using publication workflows and checklists to improve completeness, consistency, and compatibility across systems and standards. It enables public authorities, investors, companies, and CSOs to use the same structured data for data publication, review, monitoring, and oversight.
