Linked Open Data for Structured Data Formats

Structured data refers to any data that resides in a fixed field within a record or file. This can include data contained in relational databases, spreadsheets, or marked up text. Structured data may also be plain-text delimited.

The significant properties of structured data are documented in a Structured Data 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 the 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.
