- Added `has_or_had_place_of_birth` slot to capture structured birth place information with historical context. - Introduced `has_or_had_quantity` slot for capturing quantified values with units and provenance. - Created `has_or_had_service_area` slot to define geographic service areas for heritage custodians. - Implemented `is_or_was_approximate` slot to indicate uncertainty in values (dates, quantities). - Added `is_or_was_asserted_by` slot to track the agent responsible for assertions. - Introduced `Asserter` class to model agents making assertions, including types like human, automated, and AI. - Created `Quantity` class to represent quantified values with optional units and types. - Added enums for `AsserterTypeEnum` and `QuantityTypeEnum` to standardize types of asserters and quantities. - Archived outdated slots and replaced them with new structured alternatives following RiC-O conventions.

ApproximationStatus:

class_uri: hc:ApproximationStatus
|
|
description: >-
|
|
Status indicating the level of approximation or uncertainty for a value.
|
|
|
|
**PURPOSE**:
|
|
|
|
ApproximationStatus captures structured uncertainty information for values
|
|
like dates, quantities, and measurements where precision varies. This
|
|
replaces simple boolean "approximate: true/false" with richer modeling.
|
|
|
|
**UNCERTAINTY LEVELS**:
|
|
|
|
| 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" |
|
|
|
|
**CIDOC-CRM ALIGNMENT**:
|
|
|
|
CIDOC-CRM models time-span precision through E52_Time-Span with fuzzy
|
|
boundaries. ApproximationStatus provides a complementary vocabulary for
|
|
expressing certainty levels.
|
|
|
|
**USE CASES**:
|
|
|
|
1. **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
|
|
|
|

|
|
|
|
```yaml

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
