Description
Check literal endings, reject if both match, strip the recognized suffix and return recto, verso or unspecified with a recognized flag.
Historical and regional records connect source vintages, era coordinates, folio sides, time coverage and locally defined units. Literal tokens and supplied offsets can organize metadata without authenticating an archive or establishing historical calendar equivalence. Preserve the original source and its conventions.
Check literal endings, reject if both match, strip the recognized suffix and return recto, verso or unspecified with a recognized flag.
When to use this tool
Use Archive Reference Folio Side when checking the stated regional archival, chronology, coverage or unit convention.
How to use the tool and how it works
- Enter reference, 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 folioToken, side, recognized. Inspect recognized before interpreting the associated values.
Require distinct nonempty recto/verso suffix tokens. Check literal endings, reject if both match, strip the recognized suffix and return recto, verso or unspecified with a recognized flag.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| reference | Reference | Required. Text; maximum UTF-16 length 8192. |
| rectoToken | Recto Token | Required. Text; maximum UTF-16 length 8192. |
| versoToken | Verso Token | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|

{
"input": {
"reference": "f12v",
"rectoToken": "r",
"versoToken": "v"
},
"output": {
"folioToken": "f12",
"side": "verso",
"recognized": true
}
}Limitations and assumptions
- The remaining folio token is not parsed as a number or authenticated against an archive; overlapping suffix matches are rejected.
- 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 original archive and appropriate historical/calendar/unit authorities for provenance and substantive interpretation.
