The Labeler transformation adds a labeler asset that you created in Data Quality to a mapping.
A labeler asset defines a set of operations that evaluates the types of information in an input field and assigns a label to each type of data that it finds.
When you configure the transformation, you map an input field to a target field that links to the labeler asset. When the mapping runs, the transformation searches the input field for values that match the labeling criteria that the asset defines. The transformation writes the results of the labeling operation to two output fields. For more information about the output fields, see Labeler transformation output fields.
A Labeler transformation is similar to a Mapplet transformation, as it allows you to add data transformation logic that you designed elsewhere to a mapping. Like mapplets, labeler assets are reusable assets.
A Labeler transformation shows incoming and outgoing fields. It does not display the logic that the labeler asset contains or allow you to edit the labeler asset. To edit the labeler asset, open it in Data Quality.
