- Implement `normalize_linkml_alt_descriptions.py` to convert structured alt_descriptions to the expected scalar form. - Implement `normalize_linkml_structured_aliases.py` to flatten language-keyed structured_aliases into a standard list-of-objects format. - Implement `validate_linkml_schema_integrity.py` to validate the integrity of LinkML schema bundles, checking for import resolution, YAML parsing, and reference existence.

"Time-coded caption/subtitle content for video.\n\n**DEFINITION**:\n\nVideoSubtitle represents caption/subtitle tracks that provide time-coded\ntext synchronized with video playback. It extends VideoTranscript because\nsubtitles contain complete transcription PLUS temporal synchronization.\n\n**INHERITANCE FROM VideoTranscript**:\n\nVideoSubtitle inherits all transcript capabilities:\n- `full_text`: Complete subtitle text concatenated\n- `segments`: Time-coded entries (REQUIRED for subtitles)\n- `includes_timestamps`: Always true for subtitles\n- `content_language`: Language of subtitle text\n- All provenance from VideoTextContent\n\nAnd adds subtitle-specific properties:\n- `has_format`: SRT, VTT, TTML, SBV, ASS\n- `is_closed_caption`: CC vs regular subtitles\n- `is_sdh`: Subtitles for Deaf/Hard-of-Hearing\n- `includes_sound_descriptions`: Non-speech audio descriptions\n\n**SCHEMA.ORG ALIGNMENT**:\n\nMaps to `schema:caption` property:\n> \"For downloadable machine\

Distinctions (informal)
|
|
|
|
- Transcript: may be plain text; time codes optional.
|
|
- Subtitle: time-coded; typically supports translation.
|
|
- Closed captions (CC): time-coded; typically includes accessibility cues.
|
|
|
|
Formats
|
|
- SRT (.srt): simple, widely supported
|
|
- VTT (.vtt): web standard
|
|
- TTML (.ttml/.dfxp): XML-based
|
|
|
|
Segment requirement
|
|
- Unlike VideoTranscript, VideoSubtitle requires has_segment entries.
|
|
|
|
legacy_description: |

|
Preserved from earlier, more verbose description.

|
|
|
It included detailed comparisons (subtitle vs caption vs transcript),
|
|
format examples (SRT/VTT), heritage accessibility context, and notes
|
|
on YouTube subtitle track integration.
