Generating XML Model objects

Chapter 4 Working with an XML model

Generating XML Model objects

When you generate an XML model from an OOM, PowerDesigner translates OOM objects into specified XML Model objects as follows:

OOM Object	Generated object in an XML model
Class	Element. A class is generated as a child element when it has one composition link with another class
Class attribute	Element or element attribute (See generation options)
Identifier	Key
Domain	Simple type
Abstract class	Complex type
Abstract class attribute	Complex type attribute

OOM packages are generated into XML diagrams.

An OOM is generated into several XML diagrams:

A global diagram displaying a hierarchical view of all the generated elements
One diagram for each class diagram in order to keep the OOM design. The generated diagram displays the same object symbols as the source diagram

The Global Diagram displays the symbol of a root element called Application. This Application element (which has no equivalent in the source OOM) groups together all the key constraints (see Constraints page of the Application property sheet) generated from the OOM identifiers.

Select Symbol→Show Symbols to reveal the other generated XML Model objects (simple types and complex types).

XML model naming conventions
If the code of the generated XML model objects does not correspond to the target language naming conventions, you can define a code naming convention script to convert object names into codes.
For more information on conversion scripts, see section .convert_name & .convert_code macros in chapter Managing Models of the General Features Guide.
