Using properties in systems engineering.

New standards like CAEX [1] and AutomationML [2] provide new means for data exchange between engineering tools. In order to provide an unambiguous exchange of information, a common data format should be used that is based on semantically well defined data elements as defined in IEC 61360 [3]. In order to use such data elements (e.g. properties), some extensions of the model defined in IEC 61360 are necessary. This contribution describes how the property model may be used during system engineering and introduces proposals on how to extend the property model.
