Development of an interoperability model for different construction drawing standards based on ISO 10303 STEP

The purpose of this study is to develop an exchange model for the interoperability of various national standards based on the international standard ISO 10303 in construction. Several countries like Germany, Japan, and Korea have developed the drawing standards STEP-CDS, SCADEC, and KOSDIC, respectively, for the neutral drawing data exchange mechanisms among various applications. However, these standards are not naturally exchangeable due to the differences resulting from the national flavors representing the drawing elements defined in their standards. These problems can be solved using the exchange methodology, EXPRESS-X, defined in ISO 10303. In this study, an exchange model applying the standard exchange methodology has been developed by analyzing the three different drawing standards. The developed exchange model demonstrates that the interoperability among the drawing standards is feasible. In addition, the model shows that the use of the standard exchange methodology based on international standards is beneficial in many ways for the data exchange between schemata.
