About
oEmbed is an open format that allows websites to embed representations of external URLs such as videos, images, and posts from third-party services.
It defines a simple API that returns structured metadata in 
JSON or XML for generating content previews, and supports multiple content types including video, photo, link, and rich embeds.
The Web Content Accessibility Guidelines (WCAG) are an international standard developed by the W3C that defines how to make web content, including text and media, accessible to people with disabilities.
They are technology-agnostic and structured around four core principles (perceivable, operable, understandable, and robust) and define testable success criteria with three conformance levels (A, AA, AAA) used to evaluate accessibility compliance.
