description: "Structured representation of how often a device, system, or data source sends updates or refreshes data.\n**WHY A DEDICATED CLASS?**\nUpdate frequency is more than a simple string - it has: - **Quantity**: How many updates (e.g., \"5\" in \"every 5 minutes\") - **Time Interval**: The period (e.g., \"minutes\" in \"every 5 minutes\") - **Trigger-based**: Some updates are event-driven, not time-based\n**SLOT_FIXES.YAML REVISION** (lines 1893-1910): - Branch 1: has_or_had_quantity \u2192 Quantity (numeric value) - Branch 2: has_or_had_time_interval \u2192 TimeInterval (duration)\n**ONTOLOGY MAPPING**: - class_uri: dcterms:Frequency (Dublin Core) - Dublin Core `accrualPeriodicity` uses Frequency for collection update rates\n**USE CASES**: - IoT sensors: \"Every 5 minutes\", \"Hourly\", \"Real-time\" - Data feeds: \"Daily\", \"Weekly\", \"Monthly\" - Event-driven: \"On proximity trigger\", \"On change\"\n**EXAMPLES**: - Climate sensor: 5 updates per minute - Beacon: On proximity\

comments:
|
|
- Created from slot_fixes.yaml migration (2026-01-14)
|
|
- Replaces simple string update_frequency slot
|
|
- Supports both time-based and event-driven frequencies
|
|
- Uses Dublin Core Frequency class for semantic alignment
