About
The Open Graph protocol is a web metadata standard that defines how webpages are described as structured objects for use in social graphs and enables their consistent representation.
It specifies a set of 
HTML meta properties that start with "og:" (such as og:title, og:type, og:image, and og:description) to add semantic meaning to a page's content and control how that content should be represented.
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.
