The executable Internet (X Internet) brings new power and sophistication in delivering services and capabilities to users. The X Internet, both the executable Internet and the extended Internet, fundamentally alters the desktop and Internet landscapes by blurring their distinction both online and off-resulting in a new era of information technology. Authoritative and comprehensive, X Internet: The Executable and Extendable Internet examines this new paradigm from practical and strategic perspectives. It provides a roadmap for building applications that deliver X Internet capabilities. From a strategic angle, it delves into the legal aspects of using and creating this new breed of Internet applications. Discussing computer-human interaction, the book details the development of a rich Internet environment, including graphical design, multimedia, architectures, software development techniques, tools, and information management for X-enriched systems, the components that make up many of the Web 2.0 applications so popular today. It also includes appendices that contain information on a framework for auditing X systems and various guides for using audio and video and building user interfaces. X Internet systems offer almost limitless possibilities for building rich, interactive systems that increase productivity and dramatically enhance the user experience. X Internet: The Executable and Extendable Internet provides a thorough yet accessible understanding of this new Internet that is becoming critical to software development and systems management.
