Use the result while planning ingest, digitization, quality control, reporting, or preservation work where the stated rule needs to be repeatable and reviewable.

Transparency

Document uses transparency groups.

JPEG 2000

Document uses JPEG 2000 image compression.

Embedded files

Document embeds other files.

Non-PDF attachments

Embedded attachments include non-PDF formats.

Select the lowest ISO 19005 conformance part (PDF/A-1, -2 or -3) that supports the declared document features such as transparency or non-PDF attachments. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Part

Lowest sufficient ISO 19005 part number (1, 2 or 3).

Label

Conformance label such as PDF/A-2.

Rationale

Reason the selected part was required.

• Repository policies, format profiles, equipment capabilities, and descriptive standards vary. Preserve the source value and record the rule version instead of treating this utility as an authority-record or preservation-system validator.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Complement the calculation with format validation, fixity checks, provenance records, and human review. For policy decisions, apply the profile adopted by the repository rather than an undocumented local convention.

• ISO 8601 Date Interval Format Validator

  Validate a practical ISO 8601 interval subset of the form start/end. It checks Gregorian calendar dates (including leap years), clock and UTC-offset ranges, reduced-precision dates, and non-mixed calendar or week durations; it does not compare endpoint chronology.

• Annual Report Output Metrics Rollup Aggregator

  Roll up periodic output metrics such as quarterly accessions or reference counts into a count, total, mean, minimum and maximum for annual reporting.

• Country Code ISO 3166 Alpha-2 Validator

  Validate whether a normalized two-letter value is a currently assigned ISO 3166-1 alpha-2 country code. Reserved and user-assigned letter pairs are not accepted.
