- Abstract
- The development of a global model for building-project information requires a precise description of the meaning of the information to be maintained. The report presents an analysis of the conceptual structures that are available to specify that meaning using an 'as-designed' global model as an example. The model is currently under development by the Architecture, Engineering, and Construction (AEC) Committee of the Initial Graphics Exchanges Specification (IGES)/Product Data Exchange Specification (PDES) Organization. The key conclusion of the analysis is that a core semantic vocabulary is needed. The core vocabulary derives from how meaning is expressed without regard for specific domains of information. Preliminary elements of such a core vocabulary are defined. Further, a means by which that core is extended to add necessary domain-specific semantics is presented. The analysis has identified those aspects of developing a global model for building-project information that should proceed in the context of a broad interdisciplinary effort to represent information and those that require extensive technical input from the building industry.
