**ONTOLOGY ALIGNMENT**:
|
|
|
|
| Ontology | Mapping | Rationale | |----------|---------|-----------| | Schema.org | schema:caption | Media caption/subtitle |
|
|
|
|
**USE CASES**: - Video captions for hearing accessibility - Subtitles for multilingual content - Closed captions vs. open captions distinction
|
|
|
|
MIGRATED 2026-01-22: Created per slot_fixes.yaml feedback to replace simple caption_available string with structured class.'
