- Removed compliance_status slot and replaced it with has_or_had_status. - Updated has_or_had_status to use ComplianceStatus for structured representation. - Adjusted examples to reflect new structure for compliance status. - Updated documentation to indicate migration and provide details on the ComplianceStatus class.

description: |

|
A point in time with optional precision and calendar metadata.
|
|
|
|
**Purpose**:
|
|
Timestamp provides a reusable class for representing temporal instants
|
|
with explicit precision indicators. This supports EDTF-style partial
|
|
dates (year-only, year-month, full date, datetime) and calendar system
|
|
annotation for non-Gregorian dates.
|
|
|
|
**Ontological Alignment**:
|
|
- **Primary**: `time:Instant` - OWL Time instant
|
|
- **Close**: `crm:E61_Time_Primitive` - CIDOC-CRM time primitive
|
|
- **Related**: `xsd:dateTime` - XML Schema dateTime
|
|
|
|
**Use Cases**:
|
|
- Beginning/ending of time spans (TimeSpan.begin_of_the_begin, etc.)
|
|
- Validity dates (valid_from, valid_to)
|
|
- Update timestamps (updated_at, created_at)
|
|
- Historical dates with varying precision
|
|
|
|
**Precision Levels**:
|
|
- year: "1995" (EDTF: "1995")
|
|
- month: "1995-06" (EDTF: "1995-06")
|
|
- day: "1995-06-15" (EDTF: "1995-06-15")
|
|
- datetime: "1995-06-15T10:30:00" (full precision)
|
|
|
|
**Replaces** (per slot_fixes.yaml):
|
|
- `valid_to_geo` → TimeSpan.end_of_the_end: Timestamp
|
|
- `valid_to` → TimeSpan.end_of_the_end: Timestamp
|
|
- `valid_from_geo` → TimeSpan.begin_of_the_begin: Timestamp
|
|
- `valid_from` → TimeSpan.begin_of_the_begin: Timestamp
|
|
- `updated_at` → was_last_updated_at: TimeSpan
|
|
- `unesco_inscription_year` → TimeSpan.begin_of_the_begin: Timestamp
