The Open Web Platform (OWP) is a collection of Web technologies developed by the World Wide Web Consortium and other Web standardization bodies such as the Unicode Consortium, the Internet Engineering Task Force, and Ecma International.
It is the umbrella term introduced by the World Wide Web Consortium, and in 2011 it was defined as "a platform for innovation, consolidation and cost efficiencies" by W3C CEO Jeff Jaffe.
The Open Web is like something from an Arthur C. Clarke science fiction story: its a globe spanning, hypertext network containing billions of documents, conversations, and applications, used by a huge cross section of society. Who would have thought it ever would have been successful or stayed as open as it has? It's not controlled by any one government or company. Our historical closeness to the web creates a kind of myopia, where we can't see how amazing it is. It's a billion Library of Alexandria's dropped into our laps.
