Product Data Templates (PDTs) are an essential document in Building Information Modelling (BIM) and are templates which help generate information about a specific product. When a manufacturer completes a PDT it becomes a PRODUCT DATA SHEET (PDS), in other words a ‘digital’ description of the product. Subject to respecting the terms of use of the PDT, the manufacturer owns the PDS and is free to use it on its website and in any library it chooses. The manufacturer then remains responsible for the accuracy and completeness of its data on the PDS, in the normal way.
