HBIM-BASED INFORMATION SHARING FOR THE EXCHANGE AND SAFEGUARD OF MODELLING EXPERTISE

Abstract. This paper demonstrates an approach for sharing and safeguarding modelling expertise based on the use of Historic Building Information Modelling (HBIM). The approach involves the exchange of information between subjects involved in the creation of HBIM models, an exchange enhanced by Semantic Web Technologies.

HBIM datasets usually contain rich and detailed information about historic buildings and their construction; this experiment, in a slightly unusual way, deals with another type of information regarding something that happens in the background during the definition of an HBIM model: the procedures that create the complex three-dimensional geometries typical of historical architecture. This kind of information does not usually live inside BIM models and is even less likely the subject of semantic enrichment. It is however beneficial to record and make available this kind of information for several reasons, discussed in the text.
