Archive with LIMITED access - between broadly accessible and fully closed.
**Wikidata**: Q112796779 (Dim Archive)
**DEFINITION**:
Dim Archive provides access to materials but with significant restrictions
that limit who can access, when, or under what conditions. This is the
middle position in the Light/Dim/Dark access spectrum.
**ACCESS SPECTRUM**:
| Type | Access Level | Characteristics |
|------|--------------|-----------------|
| Light Archive (Q112815447) | Broadly accessible | Open to public/researchers |
| **Dim Archive** | Limited access | Restricted by criteria |
| Dark Archive (Q112796578) | No current access | Preservation only |
**RESTRICTION TYPES** (reasons for "dim" access):
1. **User-Based Restrictions**
- Researchers only (credentials required)
- Institutional affiliates only
- Nationality restrictions
- Security clearance required
2. **Content-Based Restrictions**
- Privacy-sensitive materials (personal data)
- Confidential business information
- Culturally sensitive materials
- Copyright restrictions (reading room only)
3. **Process-Based Restrictions**
- Appointment required
- Approval/application process
- Fee-based access
- Supervised access only
4. **Format-Based Restrictions**
- Physical access only (no digital)
- Specific reading room required
- No reproduction allowed
- Watermarked copies only
**SPECIAL LINKAGE: AccessPolicy → Collection**
Dim archives use AccessPolicy to document restrictions. AccessPolicy
applies to Collection instances:
```
DimArchives (custodian type)
└── manages → Collection (holdings)
└── has_access_policy → AccessPolicy
├── access_level: RESTRICTED
├── restriction_reason: (text)
├── eligible_users: (criteria)
└── access_process: (procedure)
```
**MULTILINGUAL LABELS**:
- Dim Archive (de) [uses English term]
**RELATED TYPES**:
- LightArchive (Q112815447) - broadly accessible
- DarkArchive (Q112796578) - no current access
- AccessPolicy - policy class for restriction documentation
**ONTOLOGICAL ALIGNMENT**:
- **SKOS**: skos:Concept (type classification)
- **PREMIS**: premis:RightsDeclaration for access rights
- **RiC-O**: rico:RecordSet with access restrictions
