What’s the difference between ifcxml and mvdxml? Format seems same?
ifcXML contains the same model information as an IFC STEP file (.ifc), but in XML format.
mvdXML is a machine-readable expression of a Model View Definition, a subset of the overall schema, allowing it to be used as the IFC export “template” from an application AND as a means to validate the resulting IFC file.
while the name is mvdXML, the content of the mvdXML allows to capture and exchange in a computer-readable way:
- the MVD subset of the IFC schema
- one or many Exchange Requirements that correspond to the MVD
- additional rules to validate that the received IFC Data is valid against the MVD and chosen Exchange Requirement
