The Semantic Web is the next-generation Web of structured data that are automatically shared by software agents, which apply definitions and constraints organized in ontologies to correctly(More)
Because of its success, XML is increasingly used in many different application areas, and is moving towards the center of applications, evolving from an exchange format to the native data format of application components. These developments suggest that similar to other core areas of application design, XML should be designed conceptually before the(More)
