    Dependencies between indicators, subfields, tagfields

    • Article Type: General
    • Product: Aleph
    • Product Version: 16.02

    Description:
    How can we express dependencies between indicators and subfields?
    For example, if 505 indicator 2 is blank, then subfields g, t, and r should not be present.

    Dependencies between tag(s)/indicator combinations are in check_doc_doc, but what about subfield(s) for those various tags?

    Dependencies between subfields within one tagfield are in check_doc_line, but what about indicators within that tagfield?

    Resolution:
    check_doc_line checks for dependencies between particular subfields in a particular field (optionally, of a particular bib format) but does not look at indicators.

    Additional Information

    check_doc_line, check_doc_doc, dependency, indicator,
