The theory of the Semantic Web is that systems can interact autonomously by sharing a language as well as a logical framework for making decisions. Powered by XML and RDF, the Semantic Web offers a mechanism for informing systems of the context or intent of the information described. A core element of any Semantic Web system is the maintenance of a storage repository for ontologies and instance documents. Many Semantic Web systems thus become, in effect, Content Management system, enabling the management of vast amounts of XML data and providing mechanisms for users to edit and maintain ontologies. Epigraph’s flagship product, Xcellerant, provides a visual and architectural management tool for housing all of the discrete components necessary for instituting a functional Semantic Web system, including workflow, version control, check- in/check-out, XML schema validation, ability to call elements via Web Services, user management and control, visual representation of data elements, and abstraction of the file management interface.Download File
