About

The Transparency & Consent Framework (TCF) is an open-source industry standard developed by IAB Europe that helps companies comply with GDPR and ePrivacy requirements when processing personal data in digital advertising ecosystems.

It defines technical specifications and policies for collecting and communicating user consent choices, standardizes how these preferences are shared between publishers, advertisers, and CMPs, maintains a centralized list of approved vendors, and ensures transparency by giving users clear control over how their data is used.

Really Simple Discovery (RSD) is an XML format that allows client software to discover services provided by web publishing systems.

It helps clients find endpoints for reading, editing, and interacting with website content through APIs.
