Haystack: a platform for authoring end user semantic web applications

摘要: The Semantic Web promises to open innumerable opportunities for automation and information retrieval by standardizing the protocols metadata exchange. However, just as success of World Wide can be attributed ease use ubiquity browsers, we believe that unfolding vision depends on users getting powerful but easy-to-use tools managing their information. But unlike HTML, which easily edited in any text editor, RDF is more complicated author does not have an obvious presentation mechanism. Previous work has concentrated ideas generic graph visualization Schema-based form generation. In this paper, present a comprehensive platform constructing end user applications create, manipulate, visualize arbitrary RDF-encoded information, adding another layer abstraction cake. We discuss programming environment specifically designed manipulating introduce interface concepts top allow developer quickly assemble are based data models. Also, because specifications program logic themselves describable RDF, built upon our framework enjoy properties such network updatability, extensibility, customizability - all desirable characteristics spirit Web.
