description: "Status indicating the level of approximation or uncertainty for a value.\n**PURPOSE**:\nApproximationStatus captures structured uncertainty information for values like dates, quantities, and measurements where precision varies. This replaces simple boolean \"approximate: true/false\" with richer modeling.\n**UNCERTAINTY LEVELS**:\n| Level | Label | Description | Example | |-------|-------|-------------|---------| | EXACT | Exact | Known with certainty | \"1880-03-15\" | | APPROXIMATE | Approximate | Close but not exact | \"circa 1880\" | | ESTIMATED | Estimated | Calculated/inferred | \"estimated 1875-1885\" | | UNCERTAIN | Uncertain | Significant doubt | \"possibly 19th century\" | | UNKNOWN | Unknown | Cannot be determined | \"date unknown\" |\n**CIDOC-CRM ALIGNMENT**:\nCIDOC-CRM models time-span precision through E52_Time-Span with fuzzy boundaries. ApproximationStatus provides a complementary vocabulary for expressing certainty levels.\n**USE CASES**:\n1. **Date Uncertainty**:\
|
|
\ Founding dates known only to decade 2. **Quantity Estimates**: Collection size approximations 3. **Location Precision**: Address known only to city level 4. **Historical Events**: Uncertain timing of organizational changes\n**EXAMPLE**:\n```yaml event_date: \"1880\" is_or_was_approximate:\n has_or_had_level: APPROXIMATE # was: approximation_level\n has_or_had_label: \"circa 1880\"\n has_or_had_description: \"Founding date known only to year from secondary sources\"\n```"

comments:
|
|
- ApproximationStatus replaces simple boolean approximate field
|
|
- Provides structured uncertainty modeling for dates, quantities, etc.
|
|
- Aligned with CIDOC-CRM E52_Time-Span precision concepts
|
|
- Used by is_or_was_approximate slot
