Description
Split shelfmark by nonempty delimiter and return the valid zero-based componentIndex plus componentCount.
Catalog identifiers and labels follow local formatting conventions. Splitting or recognizing a token's shape preserves structure without establishing that its identifier or classification is valid.
Split shelfmark by nonempty delimiter and return the valid zero-based componentIndex plus componentCount.
When to use this tool
Use Shelfmark Sort Component when you need one explicit catalog-label parsing or formatting step.
How to use the tool and how it works
- Enter shelfmark, delimiter, componentIndex. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read component, componentCount. Use the output convention below.

}Limitations and assumptions
- Empty components are retained; no classification scheme or numeric sorting is inferred.
- 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
Consult the cataloging scheme and source record before assigning semantic meaning or a filing order.
