The document discusses the eConstruct project which aims to develop and implement a communication technology called bcXML tailored for the European building and construction industry. bcXML will provide a common framework for product catalogues and help contractors, suppliers, and portals communicate and do business across borders by overcoming differences in languages and standards. The document also presents some use cases and a prototype demonstration of how bcXML enables searching for construction products in multiple languages and linking product catalogues to building information models.
