About
ARIA (Accessible Rich Internet Applications) is a technical specification from the W3C Web Accessibility Initiative that defines how to improve the accessibility of web content and applications, particularly those with dynamic interfaces and custom controls.
It provides a set of roles and properties that can be added to 
HTML to describe user interface elements, their relationships, and current states, enabling assistive technologies such as screen readers to interpret widgets, live updates, and complex interactions that are not natively accessible.
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.
