| Abstract |
In this paper we discuss integration of the separate knowledge possessed by the domains in the design process. Centralized data structures, showed that the AEC industry is so fragmented that the data-centric approach is not feasible, for technical and procedural reasons. The shared database, minimizing the complexity of translating different form of representation, quickly becomes too large and unwieldy to support the dynamic process of multi-disciplinary work process. We propose a distributed model that includes a mechanism to facilitate the domains’ intentions more effectively by incorporating semantics into their representations. We also present how the semantics would be authored and published through the mechanism so that a higher level of shared understanding among the domains would be achieved. We discuss several approaches of lifting modeling information that is based on the express family of languages for data modeling onto a logically rigid and semantically enhanced ontological level. We exemplify the added value of such formal notation of building models by providing several examples where generic query and reasoning algorithms can be applied to problems that otherwise have to be manually hard-wired into applications for processing building information. Furthermore, we show how the underlying resource description framework and the set of technologies evolving around it can be tailored to the need of distributed collaborative work in the building and construction industry. |
