Folio Reference Recto-Verso Notation Normalizer (r/v)
Normalize a single positive folio recto/verso notation; no foliation/pagination conversion or damaged-number inference.
Description
Folio Reference Recto-Verso Notation Normalizer (r/v): return normalized reference.
A folio is a leaf; recto and verso identify its two sides. Normalizing a reference preserves that distinction in a compact form.
This tool returns normalized reference. Use the stated units and model convention when interpreting these fields.
When to use this tool
Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.
- Check the supported input and output contract against an existing calculation or observation.
- Use the complete example to confirm units, selector spelling and result interpretation.
How to use the tool and how it works
- Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
- Run the tool. Correct input errors before interpreting an output.
- Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.
Trim the input, accept an f or fol prefix, a positive folio number and r/v/recto/verso, then emit f. followed by the number and r or v.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| folioReference | Folio reference. | Text |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.normalizedReference | Normalized reference; use the stated units and sign convention. |

"input": {
"folioReference": "fol. 12 verso"

"output": {

"normalizedReference": "f. 12v"
}
}
}Limitations and assumptions
- The tool checks this notation only; it does not verify a manuscript's foliation or catalog identity.
- Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
- Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.
Alternative or Complementary methods
Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
