buildingSMART Data Dictionary (bSDD) is a service provided by buildingSMART to offer standardized data dictionaries to describe special aspects of a planning. The structure of bSDD was also defined by buildingSMART.
Function
In May 2025 around 300 dictionaries are available, including IFC,[1] extensions to it such as Airport Domain IFC extension module[2] or claissification systems like Uniclass.[3]
The main structural parts of bSDD are:[4]
- Dictionary: A dictionary is a collection of classes:
- Class: A class describes the various object types, such as Bag drop[5] or Baggage conveyor[6] in airport planning. A class contains properties:
- Property: A property describes a part of a class, e.g. color or weight. Related properties are organized in a group:
- GroupOfProperties: A group organizes related properties, e.g. environmental properties or electrical properties.
Creating and managing a directory
Every dictionary in bSDD must be published in the name of a registered organization.[7] As soon as the content is activated, it receives an unchangeable URI. This means that the content remains permanently in bSDD and cannot be deleted - this ensures stable use of the dictionary. It is only possible to change the status to inactive if it is no longer to be used - however, the dictionary remains permanently.[7]
