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

Code

Candidate MARC organization code.

Check a MARC organization code format of up to 16 letters, digits and single interior hyphens with at least one letter, preserving the original case. 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]

Valid

True when the code satisfies the format rules.

Normalized

Trimmed code in its original case.

Issues

Format violations found; empty when valid.

• 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.

• BagIt Profile Required Tag Presence Checker

  Check which bag-info metadata elements required by a BagIt profile are absent, using the case-insensitive element-name comparison required by RFC 8493 while preserving the requested spelling in the result.

• 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.

• Handle URN Namespace Component Builder

  Assemble a Handle identifier from a numeric naming-authority prefix and local suffix, then percent-encode reserved characters in the hdl URI and resolver URL while preserving slash-delimited suffix components.
