Mapping Rules
Windchill import and export allow mapping operations that either exclude attribute information or map it to other attributes during exporting and importing operations. Mapping attributes can adapt data to new environments that cannot accept the data in its original format. PTC supports three methods of mapping:
• Mapping Through Special Rules—This is the simplest method, but is not as powerful as mapping through XSL transformation.
• Mapping Through XSL Transformation—This method requires knowledge of XML and XSL. The XSL transformation functions are called by a special rule.
• Mapping through rules that call Java functions—This method requires a software engineer with Java expertise to map data through rules that call Java functions.
Mapping rules can resolve situations presented by conflict messages during Windchill import and export. This section describes mapping rules and conflict messages.
