Industry Foundation Classes (IFC)
IFC Schema are highly complex and therefore, it is difficult for software tools to implement the entire schema. Hence, the tools are certified based on the MVDs that they support. Different tools support different MVDs. For example, the most popular BIM software currently used in Ireland, supports the following MVDs
IFC 2x3 Coordination View
IFC 2x3 Full
IFC 2x3 Custom
IFC 4 Reference View
IFC 4 Full
IFC 4 Custom

A complete list of different BIM software products and the MVDs implemented can be found on the buildingSMART website.
