buildingSMART Data Dictionary (bSDD)

The bSDD is a library of terms (classes, properties) for referencing in IDS specifications and IFC models. It is a free service provided by buildingSMART International to help users improve data quality and information consistency.

The bSDD is an "API-first" service, meaning the primary interface to interact with the content is third-party solutions that can pull the information. End-users can also access the bSDD content through a dedicated Search page.
