title: Photography Class
description: >-
Represents photography permission in a heritage custodian facility.
Models whether researchers may photograph materials (usually with personal cameras)
and under what conditions.
**MIGRATION NOTE** (2026-01-14):

`allows_or_allowed_photography` to generic `allows_or_allowed` slot
with typed class. See slot_fixes.yaml for migration specification.

Photography:
class_uri: schema:LocationFeatureSpecification
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:
- "Personal research use only"
- "No flash"
- "Fragile materials excluded"
valid_from: "2018-01-01"
