Linked Open Data for Digital Cinema Formats
Digital moving images consist of bitmap digital images or “frames” displayed in rapid succession at a constant rate, giving the appearance of movement. Digital Cinema generally refers to the technology and file formats used to create, distribute, and project motion pictures. Digital Cinema is distinct from digital video (SD, HD, UHD) and does not necessarily use standards pertaining to television or other video standards in regards to aspect ratios, frame rates, and resolution.
The significant properties of digital cinema records are documented in a Digital Cinema 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.
