- Created new YAML files for audience size and audience type slots, defining their properties and annotations. - Added archived capacity slots including cubic meters, linear meters, item count, and descriptions, with appropriate URIs and ranges. - Introduced a template specificity slot for context-aware RAG filtering. - Consolidated capacity-related slots into a unified structure, including has_or_had_capacity, capacity_type, and capacity_value, with detailed descriptions and examples.

description: >-
|
|
Permission specification for photography in reading rooms or collection areas.
|
|
|
|
**DEFINITION**:
|
|
A policy specification indicating whether researchers may photograph
|
|
materials for personal research use when consulting collections.
|
|
|
|
**SCHEMA.ORG ALIGNMENT**:
|
|
Maps to `schema:LocationFeatureSpecification` as it describes a feature
|
|
or amenity availability at a location.
|
|
|
|
**TYPICAL CONDITIONS**:
|
|
- Personal research use only
|
|
- No flash photography
|
|
- No tripods
|
|
- Some materials excluded (fragile, copyright)
|
|
- Declaration/waiver may be required
|
|
|
|
**COPYRIGHT CONSIDERATIONS**:
|
|
Photography permissions typically apply to:
|
|
- Public domain materials
|
|
- Materials where institution holds rights
|
|
- Personal research use (fair use/dealing)
|
|
|
|
Materials still under third-party copyright may have different rules.
|
|
|
|
**TEMPORAL SEMANTICS**:
|
|
Photography policies have evolved significantly:
|
|
- Pre-2000s: Generally prohibited, had to order copies
|
|
- 2000s-2010s: Gradual liberalization
|
|
- 2010s onwards: Many institutions allow free photography
|
|
|
|
**EXAMPLE**:
|
|
```yaml
|
|
allows_or_allowed:
|
|
- permitted_item: Photography
|
|
is_permitted: true

|
conditions:
