Open BIM is a universal approach to the collaborative design, realization and operation of buildings based on open standards and workflows. Open BIM is an initiative of buildingSMART and several leading software vendors using the open buildingSMART Data Model.
Open BIM Program is a marketing campaign initiated by GRAPHISOFT®, Tekla® and other members of buildingSMART® to urge and facilitate globally coordinated promotion of the Open BIM concept throughout the AEC industry, with aligned communication and common branding available to program participants.

Open BIM Certification is a technical certification system being developed by buildingSMART® to help AEC software vendors improve, test and certify their data connections to work seamlessly with other Open BIM solutions.
