Subfields |
|||||||||||||||||||||||||
| ǂa 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.
|
||||||||||||||||||||||||
| ǂc Confidence value | Describes the confidence of the agency using the process/activity identified in subfield ǂa 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.
|
||||||||||||||||||||||||
| ǂd 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. The mm and dd positions contain zeroes when the data is unknown. |
||||||||||||||||||||||||
| ǂq Generation agency | MARC organization code of the institution using the process/activity to generate the linked field. See MARC Code List for Organizations for a listing of organization codes. |
||||||||||||||||||||||||
| ǂu Uniform Resource Identifier | 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. For more information about subfield ǂu, see Control Subfields.

| ǂw Bibliographic record control number | For information about subfield ǂw, see Control Subfields |
||||||||||||||||||||||||
| ǂx 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. The mm and dd positions contain zeroes when the data is unknown.
