Ontological classification for heritage computer aided design

Recent endeavors in Computer Aided Design (CAD) have enabled creating intelligent 3D models of building assets that allow high efficiency in constructing and operating/maintaining those assets. However, in order to support this, detailed specification, classification and codification of the individual building systems and their components must be created. This entails usage and embedding of specific construction classification systems with the CAD systems utilized. While many such systems exist for new builds, there is lack of classification systems for heritage buildings, which are unique in the characteristics of their components that cannot be covered by current classification systems. This paper presents part of an ongoing research to justify and create a new Ontological Classification system for Heritage assets that can be used in conjunction with CAD systems, specifically 3D intelligent authoring tools, to specify the special requirements of Heritage components. The paper will start with a comparative study to validate creation of an “Onto-Classification” system as opposed to other systems like thesauri, taxonomies etc., including case study examples of them. This will be followed with examples of the new Onto-Classification system using a current existing Case study of Toson Palace in Egypt.
