EXPRESS Schema Generator
EXPRESS is the modeling language used by STEP for defining information model for data exchange. To support STEP-based Data exchange, Windchill should provide EXPRESS schema-specific definitions for its business objects.
Since Windchill object model is represented through DTD Schema. You need to convert the same in EXPRESS schema model. For this purpose EXPRESS Schema Generator tool has been developed. The generated EXPRESS schema can be used for subsequent STEP-based Data Exchange.
Command Usage
For a given release DTD, following command can be executed to convert DTD to .exp file (EXPRESS schema file).
java wt.stepdex.schemagenerator.GenerateExpressSchema <Windchill> <DTD file name> <Output directory>
Where:
WT_HOME : Windchill Home
DTD file name: Name of the DTD file. This file should be located in <Windchill>/loadXMLFiles.
Output directory: Optional. The default value is the directory where DTD file name is present.
For example, release specific Windchill EXPRESS schema can be generated using following command: $> java wt.stepdex.schemagenerator.GenerateExpressSchema /user/windchill standardx24.dtd
