Description
Split a name token from a year and optional one-letter suffix.
Taxonomic names, authorship strings, nomenclatural types and source-defined taxon concepts are related but distinct records. A literal token parser or source-label comparison can preserve a stated convention without resolving accepted taxonomy or establishing compliance with the applicable nomenclatural code.
Split a name token from a year and optional one-letter suffix.
When to use this tool
Use Taxon Name Year Suffix Token when checking the stated taxonomic source, name-token, date or concept-support convention.
How to use the tool and how it works
- Enter token, separator. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nameToken, year, suffix. Use the output convention below.
Split a name token from a year and optional one-letter suffix. Require nonempty separator, text before its last occurrence and exactly four digits plus optional lowercase letter after it; return numeric year and suffix.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| token | Token | Required. Text; maximum UTF-16 length 8192. |
| separator | Separator | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nameToken | Name Token | Required. Text; maximum UTF-16 length 8192. |
| year | Four-digit lexical year including 0000 under this parser; not a validated publication history. | Required. Safe integer. |
| suffix | Suffix | Required. Text; maximum UTF-16 length 8192. |

"input": {
"token": "Name|1901a",
"separator": "|"
},
"output": {
"nameToken": "Name",
"year": 1901,
"suffix": "a"
}
}Limitations and assumptions
- Year zero is permitted by the lexical grammar; no publication date, author disambiguation or nomenclatural priority is verified.
- 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 taxonomic treatment and applicable nomenclatural code, and use source-aware taxonomic resolution for accepted names, priority or type status.
