Information system collecting and providing access to digital resources.
|
|
|
|
**Wikidata**: Q1224984 (digital archive / digitales Archiv / archivo digital)
|
|
|
|
**DEFINITION**:
|
|
|
|
Digital Archive is an information system designed to:
|
|
- Collect digital resources (born-digital or digitized)
|
|
- Preserve them for long-term access
|
|
- Make them available to defined user groups
|
|
|
|
**TWO INTERPRETATIONS**:
|
|
|
|
1. **Born-Digital Archive**: Preserves materials created digitally
|
|
- Email archives
|
|
- Digital government records
|
|
- Electronic manuscripts
|
|
- Social media archives
|
|
|
|
2. **Digitized Archive**: Provides digital access to analog materials
|
|
- Digitized photographs
|
|
- Scanned documents
|
|
- Digital surrogates of physical collections
|
|
|
|
This class covers BOTH interpretations.
|
|
|
|
**SPECIAL LINKAGE: DigitalPlatformType**
|
|
|
|
Digital archives require digital infrastructure. This class links to
|
|
DigitalPlatformType to describe the platform/system characteristics:
|
|
|
|

|
|
|
|
**PRESERVATION STANDARDS**:
|
|
|
|
Digital archives typically implement:
|
|
- OAIS (ISO 14721) - Reference model
|
|
- PREMIS - Preservation metadata
|
|
- BagIt - File packaging
|
|
- METS - Metadata encoding
|
|
- Trusted Digital Repository (TDR) certification
|
|
|
|
**MULTILINGUAL LABELS**:
|
|
- digitales Archiv (de)
|
|
- archivo digital (es)
|
|
- archives numériques (fr)
|

|
|
**RELATED TYPES**:
|
|
- WebArchive (Q30047053) - specifically for web content
|
|
- InstitutionalRepository (Q1065413) - academic digital publications
|
|
- DigitalPlatformType - platform classification for infrastructure
|
|
|
|
**ONTOLOGICAL ALIGNMENT**:
|
|
- **SKOS**: skos:Concept (type classification)
|
|
- **RiC-O**: rico:RecordSet for digital collections
