Description

Greedily subtract standard Roman values including subtractive pairs and prefix the resulting uppercase numeral with Plate.

An artwork record can distinguish an edition, proof, accession, attribution, or display note. These labels preserve a stated catalog convention; they do not authenticate an object or establish ownership.

Greedily subtract standard Roman values including subtractive pairs and prefix the resulting uppercase numeral with Plate.

When to use this tool

Use Catalogue Plate Roman Number Token when you need to format a supplied art-record detail consistently while retaining its source and qualifiers.

Limitations and assumptions

  • This is a modern canonical formatting convention, not a parser or verification of a source's actual plate numbering.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Compare the resulting label with the collection catalog and the institution's documentation conventions.
