W3C

The World Wide Web Consortium (W3C) is an international body that maintains Web-related rules and frameworks.

It consists of over 350 member-organizations that jointly develop Web standards, run outreach programs, and maintain an open forum for talking about the Web. The W3C coordinates companies in the industry to make sure they implement the same W3C standards.

Each standard passes through four stages of maturity: Working Draft (WD), Candidate Recommendation (CR), Proposed Recommendation (PR), and W3C Recommendation (REC).
