Linked Open Data for Geospatial Formats

A geographic information or geographical information system (GIS) is a system for creating, storing, analyzing and managing spatial data and associated attributes. In the strictest sense, it is a computer system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically-referenced information. In a more generic sense, GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, and edit data.

The significant properties of geospatial records are documented in a Geospatial 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.
