Abstract: Facilitating the integration and collaboration between different disciplines involved in an AEC project is one of the major focuses of BIM. IFC schema provides a basis for the data share and exchange between different disciplines. However, implementation of the IFC compliant software solution for specific purpose is hampered by the lack of specific exchange requirements definitions and can't ensure complete and compatible data exchanges. Thus, there is need for IDM standard to make clear definition to the process as well as exchange requirement during lifecycle. This paper is based on research about literature on IDM and intents to make a comprehensive introduction to IDM framework, research status and methods so as to make the reader have a understanding of BIM data standards and provide a reference for the formulation of the National BIM standard.
