The buildingSMART Data Dictionary (bSDD) is a library of objects and their attributes. It is used to identify objects in the built environment and their specific properties regardless of language, so that "door" means the same thing in Iceland as it does in India.
The Data Dictionary is open and international, allowing architects, consultants, owners and operators on one side and product manufacturers and suppliers on the other from all around the world to share and exchange product information. When everyone shares the same language, the building process becomes more efficient.
The bSDD is not for specific instances of objects, but for general terms. Software developers can build on top of these definitions to create specific objects.
