ARIAType
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.
Microdata is an HTML specification used to embed structured metadata within web page content by annotating elements with machine-readable attributes.
It uses attributes such as itemscope, itemtype, and itemprop to define entities and their properties directly in markup, supports vocabularies such as Schema.org, and is one of the structured data formats supported by Google alongside 
JSON-LD and 
RDFa.
