ISAD(G) Required Field Presence Checker

ISAD(G) essential exchange-element presence audit, not every 26 element, content correctness, applicable exceptions or complete standards compliance. Independently witnessed columns in order: reference code independently present, title independently present, creator independently assessed, dates independently present, extent/medium independently present, level of description independently present. Known missing and unknown evidence stay distinct; not approval, compliance, readiness, authenticity or safety certification.

Description

ISAD(G) describes archival units using defined information elements.

ISAD(G) describes archival units using defined information elements.^{[1, 2]}

This checklist records six essential elements as independently observed evidence rather than parsing a description. Use this tool to record known present, known missing and unknown checklist evidence.

When to use ISAD(G) Required Field Presence Checker

Use this tool to record known present, known missing and unknown checklist evidence. Establish the institution, collection/material context, applicable standards or authority, reference date and measurement units.

How to use ISAD(G) Required Field Presence Checker and understand its results

Establish the institution, collection/material context, applicable standards or authority, reference date and measurement units.
Enter observedCriterionFlags, criterionKnownFlags, using the field meanings and rules below, then run the tool.
Read result.witnessedCriteria, result.knownMissingCriteria, result.unknownCriteria. Interpret each field using the units, signs and evidence rules below.
If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.

Input field	Meaning	Value type	Requirement
observedCriterionFlags	Observed criterion flags; binary 0/1 in the order documented below	list of number	Required
criterionKnownFlags	Criterion known flags; 1 means known and 0 means unknown; keep the same item order	list of number	Required

Supply exactly 6 binary criterion flags and matched binary known flags in the listed order. Return witnessed labels where both flags are 1, known missing labels where known=1 and observed=0, and unknown labels wherever known=0, regardless of the placeholder observed flag. No overall diagnosis, pass or approval is inferred.

Zero-based column	Criterion
0	reference code independently present
1	title independently present
2	creator independently assessed
3	dates independently present
4	extent/medium independently present
5	level of description independently present

witnessed={label_i:known_i=1 and observed_i=1}; missing={label_i:known_i=1 and observed_i=0}; unknown={label_i:known_i=0}

Apply the field units and exact ordering, boundary and evidence rules above.

Output field	Meaning	Value type
result	Structured result containing the calculation or selected reference fields below	object
result.witnessedCriteria	Criterion labels observed present with known evidence	list of string
result.knownMissingCriteria	Criterion labels known to be absent	list of values
result.unknownCriteria	Criterion labels whose evidence is unknown	list of values

Limitations and assumptions

Feature and criterion flags are independent annotations. Unknown evidence remains unknown; matching rules do not establish a diagnosis, cause, prediction or approval.

Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.
