The Semantic Web Agreement Group (SWAG) is an organization of interested parties working together to further the development of the Semantic Web (SW), a concept that might lead to a Web that was self-described in a way that would make it easier for programs to work with it. ( Semantic refers to the meaning of something.) Tim Berners-Lee , whose Hypertext Transfer Protocol ( HTTP ) virtually created the World Wide Web, is also the man behind the Semantic Web. Berners-Lee describes the Semantic Web as "a web of data that can be processed directly or indirectly by machines". SW is a new vision of the Web in which document components describe and comprehend relationships between various aspects of Web content, enabling machines to process data in a more intelligent and autonomous way. Because the Semantic Web would be dependent upon effective data sharing, SWAG is working towards building the support system, such as a standardized glossary to ensure that terms will be processed identically by all computer systems.
Computer systems already rely on a standardized vocabulary to communicate; this ensures that instructions (such as load , for example) are interpreted consistently. The Semantic Web would make Web documents and document components much more meaningful to the machines that process them. Markup languages have steadily progressed towards more intelligent versions. Extensible Markup Language ( XML ), for example, has much more ability to perform tasks autonomously than HTML. New adaptations, such as DARPA Agent Markup Language ( DAML ) are being developed as potential vehicles that could make it possible for the Semantic Web to function as a comprehensive universal database.
