Definition

Used to provide information about the provenance of metadata in data fields in the record, with special provision for machine generation. Field 883 contains a link to the field to which it pertains. Intended for use with data fields that have been fully or partially machine-generated, i.e., generated by some named process other than intellectual creation.

1st Indicator

Method of machine assignment.

 
blank character

No information provided/not applicable.

0

Fully machine-generated. Data in linked field was fully machine-generated.

1

Partially machine-generated. Data in linked field was partially machine-generated.

2nd Indicator

Undefined. The 2nd indicator position is undefined and contains a blank ( blank character ).

blank character

Undefined

Subfields

 
‡a Generation process

Identifies the process used to produce the data contained in the linked field. The subfield may contain a process name or some other description.

[AutoDewey is a software program which takes advantage of those places where the Library of Congress Classification (LCC) and DDC are similar enough to facilitate mapping from LCC to DDC]
‡c Confidence value

Describes the confidence of the agency using the process/activity identified in subfield ‡a to generate the linked field. The subfield contains a floating point value between 0 and 1. Either a comma or a point may be used as a decimal marker. Code 0 means no confidence and 1 means full confidence.

‡d Generation date

Date on which the linked field was generated. This also serves as the beginning of the period of validity. Date is recorded in the format yyyymmdd in accordance with ISO 8601, Representation of Dates and Times (http://www.iso.org/iso/iso8601). The mm and dd positions contain zeroes when the data is unknown.

‡q Generation agency

MARC organization code of the institution using the process/activity to generate the linked field.

See MARC Code List for Organizations (http://www.loc.gov/marc/organizations/) for a listing of organization codes.

‡u Uniform Resource Identifier

The Uniform Resource Identifier (URI), for example a URL or URN, which identifies the process used to produce the data contained in the field to which 883 is linked. The URI can lead to a textual or structured description of the process, or the URL that was used to generate the linked field's content can be provided directly, i.e., a URL invoking a web service or conveying an API call.

Substituting hexadecimal notation for diacritics and special characters in Uniform Resource Identifiers. When recording a URI in subfield ‡u, you may enter most of the spacing characters listed below as either characters or their hexidecimal equivalents. Consult the table below.

Note: Do not confuse the spacing characters listed below with their long-valid non-spacing counterparts. Use of the spacing characters will be limited almost exclusively to URLs.

Entry method Name Character Alternative entry (hex value)
Enter as character or hex value Spacing circumflex/circumflex accent ^ %5E
Spacing underscore/low line 1 _ %5F
Spacing grave/grave accent ` %60
Spacing tilde/tilde ~ %7E
Enter as hex value only vertical bar n/a %7C

1 Because the Spacing Underscore may cause problems with MARC output, users may prefer to continue entering it with the hexidecimal value %5F.

‡w Bibliographic record control number

Control number of the bibliographic record from which the data in the linked field was obtained.

‡x Validity end date

Date representing expected end of period of validity for the data in the linked field. Date is recorded in the format yyyymmdd in accordance with ISO 8601, Representation of Dates and Times (http://www.iso.org/iso/iso8601). The mm and dd positions contain zeroes when the data is unknown.

883 0   ‡8 1\p ‡a parallelrecordcopy ‡d 20120101 ‡x 20141231 ‡q NO-OsNB
‡0 Authority record control number or standard number

Subfield ‡0 contains the system control number of the related authority record or a standard identifier such as an International Standard Name Identifier (ISNI). The control number or identifier is preceded by the appropriate MARC Organization code (for a related authority record) or the Standard Identifier source code (for a standard identifier scheme), enclosed in parentheses. See MARC Code List for Organizations (http://www.loc.gov/marc/organizations/) for a listing of organization codes and Standard Identifier Source Codes (http://www.loc.gov/standards/sourcelist/standard-identifier.html) for code systems for standard identifiers. Subfield ‡0 is repeatable for different control numbers or identifiers.

‡8 Field link and sequence number

Data that identifies linked fields and may also propose a sequence for the linked fields. Subfield ‡8 may be repeated to link a field to more than one other group of fields. You are responsible for creating and maintaining the link (The system does not create or maintain these links). The structure and syntax of subfield ‡8 is:

      ‡8 [linking number].[sequence number]\[field link type]

Subfield ‡8 has three parts:

The linking number is required. It occurs in subfield ‡8 in all fields to be linked (fields containing the same linking number are linked).

The sequence number is optional and preceded by a period (.). It is used to indicate the order in which the linked fields display (lower sequence numbers display before higher ones). If used, it must occur in all subfields ‡8 containing the same linking number.

The field link type is required and preceded by a reverse slash (\). It is a code indicating the reason for the link and it follows the linking number (or sequence number, if present). Field link type is required except when subfield ‡8 is used to link and sequence 85x-87x holdings fields. These are the valid codes:

a (Action). Used to link one or more fields with another field to which the processing or reference actions relate. This code is typically used only when there is more than one 5xx field that relates to another 5xx field.

c (Constituent item). Used in a record for a collection or a single item consisting of identifiable constituent units, to link the fields relating to the constituent units. All other non-linked data elements in the record pertain to the collection or item as a whole.

p (Metadata provenance). Used in a record to link a field with another field containing information about provenance of the metadata recorded in the linked field.

r (Reproduction). Used in a record for a reproduction to identify fields linked because they contain information concerning only the reproduction. Other descriptive information in the record pertains to the original (with the exception of field 007 (Physical Description fixed field), fixed field Form, field 245 subfield ‡h (Title Statement / Medium), and field 533 (Reproduction Note)).

x (General sequencing). Used in a record to make a link between fields to show a sequence between them. The sequence could be one that orders the pieces of a long field that has been broken up, indicates the relative importance of fields within the sequence, or is used for some other sequencing purpose. Use of the sequence number in subfield ‡8 is required when this code is used.

Printing

Field 883 does not print.
