kempersc 626bd3a095 refactor(schemas): apply naming conventions to 261 class files 
- Apply Rule 39: RiC-O style hasOrHad*/isOrWas* for temporal slots
- Apply Rule 43: Singular noun convention (keywords → keyword)
- Update slot references to match renamed slot files
- Maintain schema integrity across all class definitions

StorageConditionPolicy:
class_uri: odrl:Policy
description: "Designed environmental and safety conditions for a storage facility.\n\
\n**DEFINITION**:\n\nStorageConditionPolicy specifies what conditions SHOULD\
\ BE maintained\nin a storage facility according to institutional policy, standards\n\
requirements, and preservation best practices.\n\n**CRITICAL DISTINCTION**:\n\
\n- **StorageConditionPolicy** (THIS CLASS): What SHOULD BE - designed conditions\n\
- **StorageCondition**: What IS - actual observed state\n\nThe gap between policy\
\ and reality is often significant and represents\na key transparency metric\
\ for heritage preservation assessment.\n\n**STANDARDS ALIGNMENT**:\n\nThis\
\ class captures requirements from:\n- **ISO/TR 19815:2018**: Environmental\
\ management framework\n- **EN 16893:2018**: Building specifications for storage\n\
- **EN 15757:2010**: Temperature and relative humidity control\n- **ISO 9706:2025**:\
\ Paper permanence requirements\n- **PAS 198**: Archive storage requirements\n\
- **ASHRAE**: HVAC specifications for cultural heritage\n\n**POLICY vs. OBSERVATION\
\ PATTERN**:\n\n```\nStorage Facility\n │\n ├── condition_policy → StorageConditionPolicy\
\ (THIS CLASS)\n │ ├── temperature_target: 18°C\n │ ├── temperature_tolerance:\
\ ±2°C\n │ ├── humidity_target: 50%\n │ ├── standards_compliance:\
\ [EN_15757_2010, ISO_TR_19815_2018]\n │ └── policy_effective_from: 2020-01-01\n\
\ │\n └── storage_conditions[] → StorageCondition (observations)\n \
\ ├── Observation 1: Temperature 19°C ✓ (within policy)\n ├── Observation\
\ 2: Temperature 25°C ✗ (exceeds policy)\n └── Observation 3: Humidity\
\ 65% ✗ (exceeds policy)\n```\n\n**ODRL ALIGNMENT**:\n\n`odrl:Policy` - \"A\
\ Policy is a named entity for a rule-based system\nfor specifying permissions,\
\ prohibitions, and obligations.\"\n\nWhile ODRL is primarily for digital rights,\
\ the policy pattern applies:\n- Policy defines RULES for acceptable conditions\n\
- Observations are checked against policy RULES\n- Violations trigger OBLIGATIONS\
\ (remediation)\n\n**USE CASES**:\n\n1. **Archive Climate Policy**:\n - Based\
\ on ISO/TR 19815:2018\n - Temperature: 18°C ±2°C\n - Humidity: 50% RH ±5%\n\
\ - Light: <50 lux for sensitive materials\n \n2. **Cold Storage Policy**:\n\
\ - Based on Image Permanence Institute guidelines\n - Temperature: -18°C\
\ ±2°C\n - Humidity: 30% RH ±5%\n - For film negatives and photographs\n\
\ \n3. **Art Storage Policy**:\n - Based on museum industry standards\n\
\ - Temperature: 21°C ±1°C\n - Humidity: 50% RH ±3%\n - Strict light and\
\ UV control\n"

comments:
- Policy defines INTENDED conditions, not actual state

- Gap between policy and observation is key transparency metric
- Policy should reference applicable standards (ISO, EN, PAS)
- Policy should be reviewed and updated regularly
- Multiple policies may apply to different storage zones
