bSDD Integration: Automating Data Classification in OpenBIM Workflows
Master the buildingSMART Data Dictionary API to bridge regional classification systems (CCI, Uniclass, Omniclass) with core IFC entity schemas.
In large-scale BIM projects, inconsistent object properties break automated compliance checks. The buildingSMART Data Dictionary (bSDD) acts as an online service providing standardized concepts, classifications, and property sets.
1. What is bSDD and How Does It Extend IFC?
Rather than hardcoding custom attributes into IFC files, bSDD provides globally unique identifiers (URIs) linking local project data to standardized definitions across languages and jurisdictions.
2. Querying the bSDD GraphQL and REST APIs
Integrating bSDD queries into authoring software or custom WebBIM viewers allows real-time validation of entity classifications like IfcWall and property requirements before exporting final models.
3. Automated IDS (Information Delivery Specification) Verification
Pairing bSDD data structures with buildingSMART IDS XML rules enables automated server-side model audits, ensuring submitted IFC models conform strictly to client Asset Information Requirements (AIR).
