What will the Namespace drop-down contain when starting a journey with an "Audience Qualification" event?

When starting a journey with an "Audience Qualification" event in Adobe Journey Optimizer, the Namespace drop-down is filled with the people-based identity namespace. This is because audience qualification relies on understanding and segmenting users based on their identities to determine which individuals qualify for a specific journey. In this context, people-based identity is critical as it directly relates to the audience’s characteristics and behaviors, which are essential for effective audience qualification.

The focus is on utilizing identifiers associated with individual users, such as email or user IDs, that allow marketers to tailor journeys specifically for those segments. Hence, the presence of only the people-based identity namespace ensures a streamlined process for audience identification and qualification, aligning with the objectives of the journey in question.
