### LIST-INFO Metadata Information

Chunk ID | Name | Description
--- | --- | ---
IARL | Archival Location | Indicates where the subject of the file is archived. U.S. National Archives Application: This element is an approximate equivalent to the Originator element in the Broadcast Wave BEXT chunk which records the entity responsible for the 'archiving' (creation, maintenance, preservation) of this digital item. Of all the info list chunk elements, this is the most important for Federal Agencies because it is vital to document the archival responsibility for a content item. Entity designations should be as specific as possible including a two-character county code to avoid the potential for conflict in the archiving entity’s name. The archival entity should be identified at the most specific level within the institution. U.S. National Archives Use: Strongly recommended ('required') if using LIST-INFO chunk. U.S. National Archives Formatting: Two capital letters which must be derived from ISO 3166 Country Codes One comma One space Institutional Acronym. Almost always one word all caps but there are some acronyms that are more than one word. The resource GovSpeak: A Guide to Government Acronyms and Abbreviations is suggested as a source but not required. Examples: US, NARA US, LOC/RSS
IART | Artist | Lists the artist of the original subject of the file. For example, Michaelangelo.
ICMS | Commissioned | Lists the name of the person or organization that commissioned the subject of the file. For example, Pope Julian II.
ICMT | Comments | Provides general comments about the file or the subject of the file. If the comment is several sentences long, end each sentence with a period. Do not include newline characters. U.S. National Archives Application: This element should manage identifiers associated with the encapsulating file. Each identifier will be labeled as to its origin or purpose using the 'type' and 'comment' qualifiers. Using the tag 'local' in the 'type' qualifier implies the entity identified in the IARL element. U.S. National Archives Use: Strongly recommended ('required') if using LIST-INFO chunk. U.S. National Archives Formatting: If labeled: Identifier [comma space] type [comma space] comment [semicolon-space if more than one identifier] If no labeling: Identifier U.S. National Archives Examples:
NARA | 58979818, local, principal ID original filename
NARA | 1275, local, ARC Identifier
ICOP | Copyright | Records the copyright information for the file. For example, Copyright Encyclopedia International 1991. If there are multiple copyrights, separate them by a semicolon followed by a space. U.S. National Archives Application: Information about copyright and other restrictions (donor, privacy, etc.). Usage by federal agencies will often refer to the documentation of restrictions provided by other, non- embedded metadata. If used, this element may contain the information as known at the time of embedding. U.S. National Archives Use: Optional U.S. National Archives Examples:
NARA | Some or all of this material may be restricted by copyright or other intellectual property right restrictions.
