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.
Rack is a minimal, modular interface and invocation convention that operates between Ruby web servers and web applications to standardize how HTTP requests and responses are exchanged.
It translates raw HTTP requests into a 
CGI-style environment defined by RFC 3875, supports middleware stacking for step-by-step request and response processing, and is implemented by servers such as 
Phusion Passenger, Puma, Unicorn, and 
Thin.
