If we only had used XML...

Therst part of this paper will provide a general overview over XML technology and will discuss some aspects of designing applications of XML in respect of storing and retrieving data in a standardized and ef�- cient way. This overview will focus on the essential el- ements of XML needed for data modeling. The second part will introduce a dynamic link library based imple- mentation for XML data handling out of Dymola. Consequently these considerations should lead into a discussion of how to set up standardized applications of XML for modeling and handling data in various do- mains of engineering to benet from the capabilities of XML technology for data exchange in general and specically for data handling in simulation environ- ments like Dymola.
