9.2.4 Output format of data files
This section describes the output format of data files when object classes or association classes are exported by the jamexport command.
A data file is created as a CSV file with the specified name. One data file is created for each object class or association class.
In each data file, all properties of the specified object class or association class are output according to the operation code. If no operation code is specified for a data file, N (no change) is assumed for all properties.
The key property is output to the column immediately following the operation code. Numeric values are output as is, while character strings are enclosed in double quotation marks (").
Note that a data file is created even when there is no value (data) to be exported for the properties of specified object class or association class. In this case, only the item title lines are output.
