Linked Open Data for Web Records

Web records are a collection of information, documents, or database that is sent from a server to a browser via Hypertext Transfer Protocol (HTTP) when a URL has been activated and meets the definition of Federal record and is provided via an agency’s web site.

Component parts of web content may include other record types where it may be necessary to address the significant properties of those record and data types within a separate series of records. However, similar to the category “email,” when encountering another category within web records, they are not treated as a separate category.

The significant properties of web records are documented in a Web Records 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.
