Managing Trait Rules

Last update: April 4, 2021

In Trait Builder, the Expression Builder lets you create and test rules that establish audience qualification requirements. Rules consist of key-value pairs such as color == blue or price > 100. Comparison operators establish the relationship between keys and values. Boolean expressions determine the relationship between rule groups.

Main Signal Rules Features Described

  1. The Expression Builder or Code View tabs provide an overview of the rules in your trait. The Expression Builder tab lets you create rules with fields and drop-down menus. The Code View lets you create rules by manually writing those expressions as code. The illustration above shows a simple trait composed of a signal that evaluates data for a qualifying condition where a product key equals a specific value, in this case color == "blue".

  2. The fields and controls in this section let you create signals from key-value pairs and set the relationship between them with a comparison operator. A key, operator, and value are required.

  3. The Data Explorer Options allow you to backfill trait realizations for your signals.

    NOTE
    This option is only available for Data Explorer customers. Contact your Adobe consultant for details.

  4. This section shows you an estimation of trait realizations for the past 7 days, for the signals defined in the Expression Builder, for backfilled and non-backfilled traits.

    NOTE
    This option is only available for Data Explorer customers. Contact your Adobe consultant for details.

  5. The test fields let you validate combinations of signal rules or the URLs that you want to use when sending data to Audience Manager.

Create a Trait Rule

Rules (or expressions) consist of individual or groups of key-value pairs. Comparison operators set the relationship between key-value pairs. To create a rule,provide a key, a value, select an operator, and click Add Rule.

Complete the required fields in the Basic Information section before creating trait rules.

  1. Expand the Trait Expression section and enter a key and value name. This creates a signal.

    NOTE
    Include the c_ prefix (or any other naming convention) for key variable if your event calls send data to Audience Manager using that syntax.

  2. Select a comparison operator from the Operator dropdown. The comparison operator evaluates the relationship between the elements in a signal.

    NOTE
    The Boolean OR operator establishes the relationship between multiple signals within a group and cannot be changed.

  3. Click Add Rule. The saved rule appears in the traits workspace above the data entry fields.

Example

In the example below, a user has created a new trait rule based on the product ID. To build this rule, the user provided the key productkey linked with an equals operator ( ==) to the value 2093.

Clicking Add Rule saves and moves the trait into the Expression Builder workspace.
