description: "Archive preserving materials for future use but with NO CURRENT ACCESS.\n\n**Wikidata**: Q112796578 (Dark Archive)\n\n**DEFINITION**:\n\nDark Archive is a preservation repository where materials are stored with \nNO ACCESS provided to users. The primary purpose is long-term preservation\nrather than current use. Access may be triggered by specific future events.\n\n**ACCESS SPECTRUM** (Light/Dim/Dark classification):\n\n| Type | Access Level | Purpose |\n|------|--------------|---------|\n| Light Archive (Q112815447) | Broadly accessible | Discovery & use |\n| Dim Archive (Q112796779) | Limited access | Selective access |\n| **Dark Archive** | No current access | Preservation only |\n\n**COMMON USE CASES**:\n\n1. **Digital Preservation**\n - Trusted Digital Repositories (TDR)\n - Backup/disaster recovery copies\n - Integrity verification archives\n\n2. **Rights-Restricted Content**\n - Orphan works awaiting rights clearance\n - Embargoed materials\n - Donor\
\ restrictions (sealed for X years)\n\n3. **Sensitive Materials**\n - Security-classified records\n - Privacy-protected personal data\n - Legally sealed court records\n\n4. **Format Migration**\n - Source materials preserved after migration\n - Original files kept for verification\n\n**TRIGGER EVENTS** (when dark becomes accessible):\n- Expiration of embargo period\n- Rights clearance obtained\n- Donor permission granted\n- Declassification decision\n- Original system failure (disaster recovery)\n\n**MULTILINGUAL LABELS**:\n- Dark Archive (de) [uses English term]\n\n**RELATED TYPES**:\n- LightArchive (Q112815447) - broadly accessible\n- DimArchive (Q112796779) - limited access\n- ClosedSpace - physical restricted access areas\n\n**ONTOLOGICAL ALIGNMENT**:\n- **SKOS**: skos:Concept (type classification)\n- **PREMIS**: premis:RightsStatus for access restrictions\n- **RiC-O**: rico:RecordSet with access restrictions\n- **Wikidata**: Q112796578\n\n**PREMIS INTEGRATION**:\n\n\
Dark archives typically use PREMIS for preservation metadata:\n- `premis:RightsStatus` to document access restrictions\n- `premis:endDate` for embargo expiration dates\n- `premis:Agent` to identify the responsible custodian\n"
