||The lack of industry standards and agreements for electronic presentation of information on building products is hampering seamless eWork, eProcurement and integration of value chain activities in the construction industry. Technical and trade information about building products is not available in electronic form to designers, contractors and facility managers that would make it possible for them to easily re-use it in design systems and to find, compare and procure products on-line. The eProCon project brings together nine partner organizations: the Building Information Centers in all five Nordic countries, two technology partners and two research institutes. The purpose of this consortium is to demonstrate a dynamic value adding information services network in the Nordic countries for brokering building product information by electronic means. The Building Information Centers have been brokering building product information on behalf of manufactures for more then 20 years to the construction sector, using proprietary information systems that are incompatible in content, functionality and technical solution. The primary impact the eProCon project will have on the current state of the art is enabling interoperability between these systems and allowing them to share content (and enrich the content), thus becoming one virtual service available for all Nordic end-users. The demonstrated integration platform, applying Service Oriented Architecture, includes: 1) the core integration layer enabling the existing Nordic information services and a new product portal to act as a single Nordic virtual service to its end-user, 2) the update layer enabling manufacturers and suppliers to interact with the information contained in the services and 3) the catalog layer, which enables 3rd party buy applications to access the information. The paper will report on the approach selected in the eProCon project and first prototype implementations.
