This book presents the complete Language Pyramid of Web markup languages, including; Resource Description Framework (RDF), Web Ontology Language (OWL) and OWL-Services (OWL-S) along with examples and software demos. In addition, it describes the semantic software development tools; including design and analysis methodologies, parsers, validators, editors, development environments and inference engines. The source code for the “Semantic Web Author,” an Integrated Development Environment for Semantic Markup Languages is discussed and available for download at www.web-iq.com.

The inventor of the World Wide Web, Tim Berners-Lee, is also the originator of the next generation Web architecture, the Semantic Web. Currently, his World Wide Web consortium (W3C) team works to develop, extend, and standardize the Web’s markup languages and tools. The objective of the Semantic Web Architecture is W3C has developed a new generation of open standard markup languages which are now poised to unleash the power, flexibility and above all - logic – of the next generation of Web, as well as, open the door to the next generation of Web Services.

Currently, Web Services using the .NET and J2EE frameworks are struggling to expand against the limitations of existing Web architecture and conflicting proprietary standards. With software vendors battling for any advantage, Semantic Web Services, offer a giant leap forward to the first developer to successfully exploit its latent potential to deliver semantic search, e-mail and collaborative word processing.

There are many ways in which the two areas of Web Services and the Semantic Web could interact to lead to the further development of Semantic Web Services. Berners-Lee has suggested that both of these technologies would benefit from integration that would combine the Semantic Web’s meaningful content with Web Services’ business logic Areas, such as, UDDI and WSDL are ideally suited to be implemented using Semantic Web technology. In addition, SOAP could use RDF payloads, remote RDF query and updates, and interact with Semantic Web business rules engines, thereby laying the foundation for Semantic Web Services.
