||Product modeling of buildings for data exchange standards: from IGES to PDES/STEP and beyond

||Digital data exchange problems are severe in the building community becauseof its organizational and operational complexity and the vast scope of itsinformation needs. Early CAD data exchange standards, such as the InitialGraphics Exchange Specification (IGES), dealt exhaustively with the syntaxor arrangement of the data to be exchanged. Most of the semantics or meaningof the data must be imposed by the user of the standard. Current work todevelop the first international standard, called both the Standard for theExchange of Product Model Data (STEP---the IS0 nomenclature) and the ProductData Exchange Specification (PDES---the USA nomenclature), is based on anexplicit definition of semantics at the user level. The response of thebuilding community to these two different approaches to standardization isreviewed in terms of product modeling of buildings. A number of challengesare discussed in the context of building data.
