Manuscript Shelfmark Validator (library-collection-folio format)
Screen explicitly declared library / collection / item shape only; institutions do not share a universal shelfmark grammar.
Description
Manuscript Shelfmark Validator (library-collection-folio format): return matches explicit three part shape, catalog existence verified.
A shelfmark identifies an item within a repository's cataloging system. This tool validates one explicit three-part written shape.
This tool returns matches explicit three part shape, catalog existence verified. 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.
Match library, collection and final reference components separated by space-slash-space. Apply the permitted ASCII character and length rules to each part.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| shelfmark | Shelfmark. | Text |
| Output field | Interpretation |
|---|---|
| result | Object containing the following named result fields. |
| result.matchesExplicitThreePartShape | Whether the supplied shelfmark matches the one supported three-part syntax. |
| result.catalogExistenceVerified | Always false; no catalog is queried. |
{
"input": {
"shelfmark": "Library / Collection / MS 12"
},
"output": {
"result": {
"matchesExplicitThreePartShape": true,
"catalogExistenceVerified": false
}
}
}Limitations and assumptions
- catalogExistenceVerified is false. A library using a different valid shelfmark syntax may fail this particular shape check.
- 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.
