The document discusses the open web and provides definitions of key concepts. It describes the open web as stemming from a common philosophical approach of open specifications, having open source reference implementations, and involving public participation in evolution. Web standards like HTML, CSS, and JavaScript that have broad browser support are provided as examples. Open specifications like OpenID, Microformats, and OAuth that work together in a modular way are also discussed. Examples are given of how URLs and APIs can be open and readable. The document advocates for using these open web technologies and standards to make content and data more accessible and to better connect users.
