is a language developed by the W3C which allows, by using its sets of syntactic constructors based on RDF, to represent ontologies which are understandable by machines, hence providing, apart from the mechanisms for creating concepts, instances, proprieties and axioms, three levels of expressivity: OWL Lite, OWL Description Logics (OWL DL) and OWL Full.

Abstract
The emergence of the World Wide Web made available massive amounts of data. This data, created and disseminated from many different sources, is prepared and linked in a way that is well-suited for display purposes, but automation, integration, interoperability or context-oriented search can hardly be implemented. Hence, the Semantic Web aims at promoting global information integration and semantic interoperability, through the use of metadata, ontologies and inference mechanisms. This chapter presents a Semantic Model for Tourism (SeMoT), designed for building Semantic Web enabled applications for the planning and management of touristic itineraries, taking into account the new requirements of more demanding and culturally evolved tourists. It includes an introduction to relevant tourism concepts, an overview of current trends in Web Semantics research and a presentation of the architecture, main features and a selection of representative ontologies that compose the SeMoT.
