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.

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.
