DFDL schema version and keywords

When you develop a DFDL schema, you can define key information that you want to associate with it, including the file version.

After you have deployed your DFDL schema in a BAR file, you can view the properties of the DFDL schema file. The properties of the DFDL schema file include the deployment dates and times, the modification dates and times (the default information that is displayed), and any additional keyword information that you have set.

Keywords

You can define keywords anywhere in your DFDL schema by using either XML comments or the XML Schema documentation annotation facility. Keywords must follow certain rules to ensure that the information contained in the file can be parsed. The following examples show the type of information that you can define:
  • $MQSI Version=1.2 MQSI$
  • $MQSI Author=John Smith MQSI$
The following table contains the information that is displayed:
