Which feature contains select data that has been mapped and ingested?

• A. Attribute Library
• B. Segment
• C. Rule Builder
• D. Publish

Answer: (A)

The feature that stores attributes after they’ve been mapped and ingested is the Attribute Library. Once source data is mapped and loaded, each data element or field is defined in this library with its metadata, creating a centralized reference of the attributes you can use across the platform. This makes the ingested data discoverable and consistent for downstream tasks like segmentation, rule-building, or publishing. Segments describe groups of records built from those attributes; they don’t store the actual ingested data themselves. Rule Builder is where you define logic to derive new attributes or transform data, not where the ingested data is kept. Publish is the process of sending data to external systems, not a storage location for mapped data.
