Description
Accept exactly one matching suffix whose preceding tail is a positive integer without leading zero, and return folio number and side token.
Historical and public-register references combine repositories, series, titles and local identifiers. A syntactic token or hierarchy count helps organize records without authenticating the source or establishing a document's historical or legal meaning.
Accept exactly one matching suffix whose preceding tail is a positive integer without leading zero, and return folio number and side token.
When to use this tool
Use Public Register Folio Token when you need a literal archival or public-register record operation.
How to use the tool and how it works
- Enter token, prefix, rectoToken, versoToken. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read folio, side. Use the output convention below.
Require nonempty prefix and distinct recto/verso suffixes, with a prefixed token. Accept exactly one matching suffix whose preceding tail is a positive integer without leading zero, and return folio number and side token.1

}Limitations and assumptions
- Ambiguous overlapping suffix matches are rejected. Parsing does not authenticate a manuscript, resolve a catalog reference or infer its foliation convention.
- 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.
Alternative or Complementary methods
Consult the source repository's catalog and description conventions for identity and interpretation. Preserve original references and resolve language, hierarchy and identifier rules before treating a token match as an authenticated record.
