sibility for an increasingly large proportion of the development activities, they have to communicate increasingly lar- ger and more complex amounts of data with the shipyards. The exchange of the CAD data is no longer enough. If this data is to be efficiently proces- sed, the recipient needs structure information, attributes and other metadata normally stored in a product data management (PDM) system. It may be the case that this metadata also needs to be made available to partners who themselves are not yet using a PDM system.
