DD – Data Dictionary

MVD – Model View Defination

BCF – Building Collaboration Format

Building Collaboration format was originally developed by Finnish buildingSMART members, Tekla and Solibri, who together developed a way to exchange intelligent messages between different BIM software. The message contains the location of the selected elements and a commentary that is attached to them, so that the receiving program can find the chosen scene and highlight the desired components. A very small, an XML-based file can be easily transfered between the disciplines. By now, the BCF has implemented by a number of software such as Tekla Structures, Solibri Model Checker, CADS Planner and the DDS Architecture.
