Recommendation ITU-T Y.3701 provides the functional requirements for collaborative data processing in data platforms. It describes the framework for enabling multiple users and systems to work together on large datasets through integrated data pipelines, shared workspaces, distributed provenance tracking, and secure access control. This Recommendation extends established big data activities and roles—such as CDP provider, data service provider, and CDP customer—to ensure scalable, reliable, and efficient collaborative processing within a big data ecosystem.
