 Since the introduction of the Semantic Web concept by Tim Berners-Lee in 1999, there has been growing interest and application of the W3C (World Wide Web Consortium) standards to provide web-scale semantic data exchange, federation, and inferencing capabilities.Syntactic interoperability, provided by for instance XML or the SQL standards, is a pre-requisite to semantic.It involves a common data format and common protocol to structure any data so that the manner of processing the information will be interpretable from the structure.
