PSD for IFC4 summary

The purpose of the Property Set Definition PSD schema is to provide an XML schema definition for defining properties and property sets outside of the IFC specification, but including information, such as applicable IFC entities or types. It is used to define the IFC defined property sets and properties, but is can also be used to:

  • define regional or project specific property sets and properties
  • define a mapping, e.g using XSLT, between the PSD schema and another, application specific property definition schema, in order to translate the IFC defined property content into various applications.
