|
|
A subject topic instance assigned to a heritage resource.
|
|
|
|
**DEFINITION**:
|
|
|
|
Topic represents a SPECIFIC subject topic assignment (instance)
|
|
as opposed to TopicType which represents the CATEGORY of topics.
|
|
|
|
**CRITICAL: TYPE vs INSTANCE**
|
|
|
|
| Aspect | TopicType | Topic (This Class) |
|
|
|--------|-----------|-------------------|
|
|
| **Nature** | Classification/category | Specific topic instance |
|
|
| **Examples** | GENEALOGY, CIVIL_REGISTRY | "Civil Registry in Utrecht 1811-1900" |
|
|
| **Properties** | Category metadata | Specific subject term, scope |
|
|
| **Cardinality** | ~20-50 types | Many instances |
|
|
|
|
**USAGE**:
|
|
|
|
Topics are linked to heritage resources (finding aids, collections, etc.)
|
|
via the is_or_was_categorized_as slot:
|
|
|
|
```yaml
|
|
finding_aid:
|
|
is_or_was_categorized_as:
|
|
- has_or_had_type: GenealogyTopic
|
|
has_or_had_label:
|
|
- label_value: "Genealogy"
|
|
language_code: "en"
|
|
- has_or_had_type: CivilRegistryTopic
|
|
has_or_had_label:
|
|
- label_value: "Burgerlijke Stand"
|
|
language_code: "nl"
|
|
```
|
|
|
|
**MIGRATION**:
|
|
|
|
Replaces bespoke `topic` slot (string list) with structured Topic class.
|
|
