The Semantic Web adds a layer of logic and metadata to the current World Wide Web. By utilizing traditional Artifical Intelligence (AI) and Knowledge Representation (KR) techniques for both the construction of new documents and linking of existing ones, the Semantic Web facilitates machineto-machine (or 'agent-to-agent') communication. Lisp’s proven reliability and flexibility in AI and KR make it ideal for constructing intelligent Semantic Web applications. In this paper, we survey the current use of Lisp on the Semantic Web, and suggest some potential uses of it in the future. We conclude the paper with descriptions of Lisp in selected Semantic Web projects that demonstrate its strength and usability.
