This page covers the Chapter name reporting dimension. See Chapter name for how to collect this variable.
The Chapter name dimension surfaces the human-readable title of each chapter (for example, "Pilot Episode - Opening").
How this dimension is populated
Chapter name is set by the player on every media.chapterStart event.
a.media.chapter.friendlyName to an eVar.evar1-evar250, post_evar1-post_evar250 (the eVar that your processing rule maps a.media.chapter.friendlyName to)Classification approach
Adobe creates the Chapter name classification structure automatically when Media Chapters is enabled for the report suite. You are responsible for populating and maintaining the classification using Classification sets.
This approach provides a guaranteed 1:1 relationship between each chapter ID and its friendly name. Classification updates apply retroactively across all historical data for that ID.
Processing rule approach
Create a Processing rule that maps a.media.chapter.friendlyName to an eVar. This approach captures the friendly name as a per-hit value without requiring classification maintenance.
The trade-off is that you lose the guaranteed 1:1 relationship between the chapter name and the parent Chapter dimension. If your implementation sends inconsistent values for the same chapter ID across events, multiple names can appear under the same chapter. Updating a value only applies to data moving forward.
Dimension items
Each item is the literal chapter title reported on media.chapterStart.
