. . . . "An IFC2x3 file, describing all the elements compos- ing the I3M building, was used in this project. It was obtained from the company in charge of the construction of this building and it was generated using the Revit CAD software 3 . Only a small portion of the IFC file is needed in the WiseNET system. Therefore, to improve the ontology performance, only the required information will be extracted from the IFC file and populated in the ontology." . . . . "2019-11-12T18:05:11+01:00"^^ . .
