label: Access Restricted

definition: Collection contents are restricted access

accepted values: true

usage notes: This tag is only used on items of mediatype collection (it will have no affect on items of any other type). This tag should only be assigned by internal IA admins.

example: true

required: No

repeatable: No

label: Access Restricted Item

definition: Identifies item that is access-restricted

accepted values: true

usage notes: Only used on items, not collections. Automatically added to items in an access-restricted collection at the end of any task.

label: Date Added to Public Search

definition: 2019-12 and later dates: represents time item was added to public search engine. Earlier dates: Date and time in UTC that the item was created archive.org

accepted values: YYYY-MM-DD HH:MM:SS YYYY-MM-DD

usage notes: Beginning in December 2019 when item was first added to public search engine. It is added during the first task where the item does not have noindex present in meta.xml. The field is not changed or removed if the item is subsequently removed from public search. Prior to December 2019, Addeddate was automatically set when the item directory is been created in our file system. In many cases, the addeddate will be very similar to the publicdate. However, in some cases we create an item directory with metadata but no media files prior to the media being scanned. The addeddate reflects when the item was created, regardless of when the media was added to the item. When the media is added at a later date and a derive.php task is run, the publicdate will be added to the item.

example: 2017-03-28 22:05:46

required: No

repeatable: No

example: mode/1up

required: No

repeatable: Yes

definition: Location of physical item in the Physical Archive

example: yes, no

required: No

repeatable: Yes

internal use only: No

defined by: user admin

edit access: user admin

label: Collections

definition: Indicates to the website what collection(s) this item belongs to.

accepted values: Must be a valid identifier

example: prelinger

usage notes: Required for all items except “fav-username” collections. Always list the item’s primary collection first in meta.xml; this is the collection the item “belongs” to. The primary collection often represents the entity that contributed or created the content. Uploaders can only choose from collections that they have privileges for. General uploaders with no special privs can only upload to selected “Community” collections or the test_collection. Items in the test_collection are removed from the site after 30 days. **Parent collections: **If the parent collections of an item’s collections are not already included in the item’s own collection list, they will be automatically added (at the end of the next task on the item). Here, more specifically, is how that addition takes place: All of the item’s currently listed collections are considered in turn. For each of them, we trace its ancestry all the way up to the top-level collection (usually a mediatype); in tracing ancestry, we consider only the primary (first-listed) parent collection at each step. If the original item is itself a collection, we include the top-level collection, otherwise we don’t. Any collection we encounter during this traversal of the hierarchy that isn’t already in the item’s collection list gets added to the end of the list. For example, if the original item starts with collections A and B listed, we find A’s primary parent (call it A-P), that collection’s primary parent (A-P-P), etc., until we hit a mediatype; all of those that aren’t already listed get added, including the mediatype if the item itself is a collection. Then we do the same for B and its primary parent B-P, B-P-P, etc.

required: No

definition: condition of the artwork or printed materials that accompany a media item

accepted values: Mint Near Mint Very Good Good Fair Worn Poor Fragile Incomplete None Unknown

example: Good

usage notes: Defines the condition of the artwork or printed materials that accompany the media in an item. In LPs this is used for album covers and sleeves. “Incomplete” should be used when we know that artwork/printed materials are missing. “None” should be used when the item has no artwork/printed materials and we know it is not supposed to have any. “Unknown” should be used when artwork/printed material MAY be missing, but we cannot verify.

required: No

repeatable: No

label: Contributor

definition: The person or organization that provided the physical or digital media.

accepted values: String

usage notes: For physical items that have been digitized, contributor represents the library or other organization that owns the physical item. For born-digital media, contributor often represents the organization responsible for the distribution of the content (e.g. a radio station or television station).

label: Coverage

definition: Geographic or subject area covered by item

accepted values: String

usage notes: The preferred use of this field is to signify a geographical location that relates to the item. For example, in the TV and radio collections, we use the ISO 3166 location code for the country and state/territory of the station being recorded.

example: GB-LND

required: No

repeatable: Yes

definition: The individual(s) or organization that created the media content.

usage notes: For items provided by libraries, the creator is often listed using the Library of Congress Name Authority Headings, http://authorities.loc.gov/ For items from other sources, the creator is often listed as first name and surname. When an item was created by an organization, such as a government agency or a production company, use the full name of the organization. This field represents the entity who created the media, not the person who uploaded the media to archive.org (though these may be the same person). All alphabets supported.

example: Austen, Jane, 1775-1817, Ralph Burns

label: Curation

definition: Curation state and notes

accepted values: String

usage notes: Curation is a compound field with “sub-fields”: curator, date, state, and comment. - Curator is the email address of the person who added the curation tag. - Date is the UTC time and date the curation tag was added, in YYYYMMDDHHMMSS format. - State can be: dark, approved, freeze, un-dark or blank - Comment can be a code used by the scanning center team to indicate issues found during QA, or a text string with some other curation comment (e.g. information about why an item was frozen or made dark). Items uploaded into open collections are generally checked by malware detection software, and the curation field will contain the results of that check.

example: [curator]lenscriv@archive.org[/curator][date]20160504125613[/date][state]approved[/state][comment]199[/comment], [curator]malware@archive.org[/curator][date]20140321085621[/date][comment]checked for malware[/comment]

required: No

label: Publication Date

definition: Date of publication

accepted values: String

usage notes: We encourage people to use YYYY, YYYY-MM, or YYYY-MM-DD for this field, but sometimes exact dates are not possible to determine. Other common usages: [YYYY] (brackets) when a date is not certain; c.a. YYYY (c.a.) when a date is approximate; and [n.d.] when a date is unknown (you may also leave the field blank in this case). If an item has a date range, such as YYYY-YYYY, we currently index only the first date in the range. Books, movies, and CDs often only have YYYY for a publication date. Magazines often have YYYY-MM for a publication date. Concerts and articles often have YYYY-MM-DD publication dates. Use the most specific verifiable date you have access to. When the item is a digitial representation of a physical piece of media (e.g. a book, a 78rpm disc, etc.) the publication date should represent the date that the specific physical item was published. A book may have been written in 1850, and then an edition was republished in 1885. If the digitized version is the edition republished in 1885, use 1885 as the publication date (not 1850).

example: 1965, 2013-05-25, [n.d.]

required: Recommended

repeatable: Yes

label: Item Description

definition: Describes the media stored in the item.

accepted values: String, can contain links, formatting and images in html/css. Currently, with Collections, it can also contain raw Javascript, but we plan to remove this soon.

usage notes: May be about the media content (e.g. a description of the book’s plot), the physical item it represents (e.g. missing or damaged pages in the physical book that was digitized), the creator of the media (e.g. author biographical info that relates to the book), or any other information that may help a user understand the item or its context. All alphabets are supported.

example: Cinemascope homage to the city of San Francisco made by amateur filmmaker and inventor Tullio Pellegrini.

required: No

repeatable: No

definition: For partner-funded scanned books (no boxid), this allows a MARC record in the item to overwrite metadata fields in meta.xml

accepted values: true

usage notes: When this field is NOT present for partner scanned books (no boxid), metadata from a MARC record will only be used to automatically fill in EMPTY metadata fields in meta.xml, and fields that already have metadata in them will be left as-is. Adding force-update to the item causes MARC to overwrite all fields that can be extracted, regardless of whether they already contain information or not.

label: Language

definition: The language the media is written or recorded in.

accepted values: String

usage notes: For items provided by libraries, the language is often provided as a 3 letter MARC language code (e.g. eng), https://www.loc.gov/marc/languages/ For other items, the language is often written out as the full name (e.g. English). Not all items have a language associated with them (e.g. instrumental music), but when there is written or spoken language we are able to do some sorts of processing better when we know the language. To skip OCR on an item, set the value to None When an item contains no OCRable content, you will sometimes see the language set to zxx. Language is particularly important for text items so that we can do the best job with optical character recognition processing.

example: eng, Italian, None
