The document discusses eConstruct, a European project to develop standards for e-business and e-commerce in the construction industry. It outlines three key aspects needed: 1) a communication grammar (bcxml) to define data exchange; 2) a taxonomy of common terms; and 3) software to enable exchange via catalogues, taxonomies and project databases. Current results include the bcxml model, an xml server, and applications like an IFC browser and catalogue tool. The goal is to prepare the industry for more advanced e-business on next generation internet platforms.
