Creating an output structure with key/value pairs

Create a structure containing an element with a Map group type.

Procedure

In the Data Mapper tab, expand the Hierarchical Mapper node and right-click Structures.
Click New > Structure.
In the wizard that opens, select Create a new structure where you manually enter elements and click Next.
Select a folder and enter a name for your structure, then click Next.
Select a representation, JSON in this example, and click Finish.
An empty structure is created, you can create its elements.
Right-click the section on the left of your workspace and click New Element to create a root element, and keep the default properties.
Right-click the root element to create a new child element named items.
In the items element's parameters, change the value of the Group Type parameter to Map.
If you have installed the R2023-11 Talend Studio monthly update or a later one, an entry loop containing a key and a value element is automatically created. Otherwise, you should create these manually.
Create two child elements in the value element, named name and description.
Save your structure.

Your structure looks like this:
