kempersc ca4a54181e Refactor schema files to improve clarity and maintainability
- Updated WorldCatIdentifier.yaml to remove unnecessary description and ensure consistent formatting.
- Enhanced WorldHeritageSite.yaml by breaking long description into multiple lines for better readability and removed unused attributes.
- Simplified WritingSystem.yaml by removing redundant attributes and ensuring consistent formatting.
- Cleaned up XPathScore.yaml by removing unnecessary attributes and ensuring consistent formatting.
- Improved YoutubeChannel.yaml by breaking long description into multiple lines for better readability.
- Enhanced YoutubeEnrichment.yaml by breaking long description into multiple lines for better readability.
- Updated YoutubeVideo.yaml to break long description into multiple lines and removed legacy field name.
- Refined has_or_had_affiliation.yaml by removing unnecessary comments and ensuring clarity.
- Cleaned up is_or_was_retrieved_at.yaml by removing unnecessary comments and ensuring clarity.
- Added rules for generic slots and avoiding rough edits in schema files to maintain structural integrity.
- Introduced changes_or_changed_through.yaml to define a new slot for linking entities to change events.

description: 'A temporal segment of audio containing a detected audio event.
**DEFINITION**:
AudioEventSegment represents a bounded temporal portion of audio content
where a specific type of audio event has been detected. This includes:
- Speech segments (with optional speaker/language info)
- Music segments (with optional genre/type info)
- Silence segments (gaps between audio)
- Sound event segments (applause, laughter, ambient sounds)
- Noise segments (for quality assessment)
**RELATIONSHIP TO VideoTimeSegment**:
AudioEventSegment is a specialized sibling of VideoTimeSegment:
- Both extend CIDOC-CRM E52_Time-Span concept
- VideoTimeSegment: general video temporal segments
- AudioEventSegment: audio-specific event segments
**AUDIO EVENT TYPES**:
| Event Type | Description | Example |
|------------|-------------|---------|
| SPEECH | Human speech detected | Interview segment |
| MUSIC | Music detected | Background soundtrack |
| SILENCE | Very low or no audio | Gap between segments |
| SOUND_EVENT | Non-speech/music sounds | Applause, footsteps |
| NOISE | Noise/interference | Quality issue marker |
| MIXED | Multiple event types | Overlapping audio |
**HERITAGE USE CASES**:
| Content Type | Application |
|--------------|-------------|
| Oral histories | Speech segment identification |
| Virtual tours | Background music detection |
| Lecture recordings | Audience reaction segments |
| Conservation videos | Narration vs ambient sound |
| Archival footage | Audio quality assessment |
**PROVENANCE**:
Created as part of slot migration (Rule 53) from deprecated
`audio_event_segments` slot to generic `has_or_had_segment` pattern.
