Reusing a JSON message, a JSON object, or a JSON array in a message map

In the Graphical Data Mapping editor, you can reuse JSON objects and JSON arrays that you define by using the Add User-Defined function. You can also define reusable JSON structures with an XML schema.

About this task

You can reuse JSON objects and JSON arrays between message maps or between message assemblies.

You can use any of the following methods to define a JSON message, a JSON object, or a JSON array that you plan to reuse in a map:

• Define a JSON message, a JSON object, or a JSON array by using the Add User-Defined function. Then, choose any of the following methods to reuse an existing JSON definition:
  • Use copy and paste functions available in the map through the menu.
  • Use the Browse functionality that is available when you change the type of an element in your map.

  For more information, see Graphically modeling a JSON message in a message map, Graphically modeling a JSON object in a message map and Graphically modeling a JSON array in a message map.

• Define a JSON message, a JSON object or a JSON array with an XML schema. Then, use the Cast function to reuse the JSON object or JSON array definition.

  For more information, see Modeling a JSON message for use in a message map by using an equivalent XML schema model.

What to do next

Deploy the message map and verify that the output message is valid. For more information, see Troubleshooting a message map.
