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 a set of recommendations for making web content more accessible, developed by W3C.
