Chapter 2 Resource Files and the Public Metamodel

The PowerDesigner XML Model File Format

All model files in PowerDesigner have an extension that corresponds to the module in which they are saved. For example, a model saved in the object-oriented module has the extension OOM. Beside the file extension, you can decide a format for saving your models:

BIN (Binary) - files are smaller and significantly quicker to open and save
XML – larger and slower than binary files, but manipulable with standard XML editors. There is a DTD for each different kind of model file in the \DTD folder in the PowerDesigner installation directory.
