Format Descriptions for Generic Formats

>> Back

Generic formats are very widely applicable. For example: specifications for wrappers (e.g., RIFF and ISO_BMFF), bundling formats (e.g., METS and AES-31), and encodings (e.g., UTF-8 and IEEE 754-1985).

Inclusion of a format does not imply that it is preferred or acceptable for Library of Congress collections. Conversely, omission of a format from the list does not imply that it is not preferred or acceptable. See the Recommended Formats Statement for more information.

Descriptions will be drafted, added and updated over time. Persons with specialized knowledge are encouraged to review and comment on the descriptions using this contact form.
