kempersc 6c3fa6b5a3 Remove deprecated slots and add new slot definitions for enhanced data modeling 
- Deleted obsolete slot definitions for work_location and workshop_space.
- Introduced new TaxonName class to represent scientific taxonomic names with detailed attributes.
- Archived existing slots related to surname_prefix, target_name, taxon_name, terminal_count, text_region_count, title, title_proper, total_chapter, total_characters_extracted, total_connections_extracted, track_name, transcript_format, traveling_venue, type_label, type_status, typical_responsibility, unesco_domain, unesco_inscription_year, unesco_list_status, uniform_title, unit_name, used_by_custodian, uv_filtered_required, valid_from_geo, valid_to_geo, validation_status, variant_of_name, verification_date, viability_status, within_auxiliary_place, and within_place.
- Updated slot descriptions and structures to improve clarity and compliance with standards.

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)\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\n\
1. **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
- Actual conditions tracked separately in StorageCondition observations
- 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
