Audiobook Metadata
Interop Invariant
External compatibility with ABS/Plex/Apple Books is required. Compatibility
claims must match current code and product decisions.
ABB does not read or write Apple movement tags (MVNM/MVIN). Series uses
ffprobe-visible tags plus mirrored mp4ameta freeform atoms.
Series Tag Strategy
For series metadata, write both:
- ffprobe-visible tags:
series, series-part
- mp4ameta freeforms: canonical
----:com.apple.iTunes:series /
----:com.apple.iTunes:series-part plus uppercase iTunes mirrors
----:com.apple.iTunes:SERIES / ----:com.apple.iTunes:SERIES-PART
Intent semantics (set | clear | noop), the Outcome Plan, and naming-to-artifact
flow are owned by src-tauri/src/metadata/AGENTS.md and src/lib/tauri/AGENTS.md.
Verification
- Verify ffprobe-visible tags:
ffprobe -v quiet -print_format json -show_format output.m4b | jq '.format.tags'
- Verify freeform atoms with mp4 tooling (for example
AtomicParsley).
- Validate behavior in ABS/Plex/Apple import workflows when modifying mappings.
