- Introduced abstract class ConflictType to define a taxonomy for various conflict types affecting heritage institutions. - Added concrete subclasses in ConflictTypes.yaml, detailing specific conflict types such as ArmedConflict, NaturalDisaster, CivilUnrest, Terrorism, Looting, Neglect, Occupation, and Sanctions. - Implemented Permission and PermissionType schemas to represent authorization requirements for accessing heritage materials, including subclasses like BishopsPermission and InstitutionalAffiliation. - Created SocialNetworkMember class for representing members in social/professional networks, facilitating heritage sector network analysis. - Established slots for canonical access rules, conflict status, and connection metadata, enhancing the data model for heritage custodians. - Developed ConnectionDegree and ConnectionDegreeType classes to represent degrees of connection in social networks, with subclasses for first, second, and third-plus degrees. - Added slots for birth dates in EDTF and ISO formats, improving the representation of heritage custodian entities.

description: 'Represents temporal extent with fuzzy boundaries following CIDOC-CRM pattern.
|
|
|
|
|
|
E52_Time-Span models uncertainty in temporal bounds through four properties:
|
|
|
|
- P82a (begin_of_the_begin): Earliest possible start time
|
|
|
|
- P81a (end_of_the_begin): Latest possible start time
|
|
|
|
- P81b (begin_of_the_end): Earliest possible end time
|
|
|
|
- P82b (end_of_the_end): Latest possible end time
|
|
|
|
|
|
**Example**: "Founded sometime between 1800-1805, closed between 1950-1955"
|
|
|
|
- begin_of_the_begin: 1800-01-01 (earliest founding)
|
|
|
|
- end_of_the_begin: 1805-12-31 (latest founding)
|
|
|
|
- begin_of_the_end: 1950-01-01 (earliest closure)
|
|
|
|
- end_of_the_end: 1955-12-31 (latest closure)
|
|
|
|
|
|
**Use Cases**:
|
|
|
|
- Custodian founding/dissolution dates with uncertainty
|
|
|
|
- Historical event temporal bounds
|
|
|
|
- Archival record date ranges
|
|
|
|
|
|
**DO NOT USE FOR**: Database record metadata (use schema:dateCreated/dateModified)

**EDTF PATTERNS**:
|

| Pattern | Meaning | Example |
|
|
|---------|---------|---------|
|
|
| `YYYY-MM-DD` | Full date | `1970-08-15` |
|
|
| `YYYY-MM` | Year-month | `1970-08` |
|
|
| `YYYY` | Year only | `1970` |
|
|
| `YYYX` | Decade | `197X` (1970s) |
|
|
| `YYYY~` | Approximate | `1970~` (circa) |
|
|
| `YYYY?` | Uncertain | `1970?` |
|
|
| `XXXX` | Unknown | Requires provenance |
|

comments:
|
|
- Handles temporal uncertainty common in heritage contexts
|
|
- 'Precise dates: Set begin_of_the_begin == end_of_the_begin (and same for end)'
|
|
- 'Unknown start: Set begin_of_the_begin to earliest plausible date'
|
|
- 'Unknown end: Leave end_of_the_end as null (ongoing/present)'
