Linked Open Data for Email Formats
Email records are created or received via an electronic mail system, including brief notes, formal or substantive narrative documents, and any attachments, such as word processing and other electronic documents, which may be transmitted with the message.
The significant properties of email records are documented in the Email Preservation Plan, which can be used as test criteria for tools and processes used in format transformations.
NARA makes its Linked Open Data available in Resource Description Framework Terse RDF Triple Language or RDF Turtle (.ttl files). These files can be opened in any text editor. The Digital Preservation Framework as Linked Open Data includes the same elements as are available in the version of the Preservation Plans on GitHub.
These plans are not exhaustive nor universally applicable proposed actions and recommended or endorsed tools: these represent file formats and variant versions in NARA holdings, the current NARA risk assessment, processing capabilities, and tools in use at NARA.
