OpenBIM

OpenBIM is the practice of BIM in a vendor-agnostic manner. For BIM to be vendor-agnostic, BIM data must be defined using an open data standard, and BIM practices should follow standardised workflows. An example of OpenBIM involves sharing BIM data using IFC and DXF file formats. An example of closed, or proprietary BIM, is sharing BIM data using RVT and DWG file formats.
