Neo Vintage Year Boundary Screen
Screen a production year against explicit collector-supplied neo-vintage boundaries without claiming a universal 1980–2000 definition.
Description
Neo-vintage is a collector category with variable year boundaries.
Neo-vintage is a collector category with variable year boundaries. A caller-selected window makes the intended classification explicit.1
Screen a production year against explicit collector-supplied neo-vintage boundaries without claiming a universal 1980–2000 definition.
When to use Neo Vintage Year Boundary Screen
Use this tool to screen a production year against explicit collector-supplied neo-vintage boundaries without claiming a universal 1980–2000 definition.
Choose a supported lookup focus or prepare the measured values, documented evidence and caller-selected limits requested. Use the exact field names and confirm their units or date format.
How to use Neo Vintage Year Boundary Screen and understand its results
- Choose a supported lookup focus or prepare the measured values, documented evidence and caller-selected limits requested. Use the exact field names and confirm their units or date format.
- Enter earliestYear, latestYear, productionYear using the field table and calculation rules, then run the tool.
- Read classification, definitionCaution, window. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| earliestYear | Caller-defined earliest year | integer | Required |
| latestYear | Caller-defined latest year | integer | Required |
| productionYear | Production year | integer | Required |
Enter safe integer production/earliest/latest years with earliest≤latest. Return beforeWindow, afterWindow or inclusive withinWindow, the two-value window and definition caution. Signed years and equal boundaries are accepted.
before if year<earliest; after if year>latest; otherwise withinWindow Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| classification | Caller-window classification | string; one of "beforeWindow", "withinWindow", "afterWindow" |
| definitionCaution | Neo-vintage definition caution | string |
| window | Caller-defined year window | list of number |
{
"input": {
"earliestYear": 1980,
"latestYear": 2000,
"productionYear": 1990
},
"output": {
"classification": "withinWindow",
"definitionCaution": "Neo-vintage is a collector category without one universal date rule; these boundaries are caller-supplied and production year alone does not establish value or significance.",
"window": [
1980,
2000
]
}
}Limitations and assumptions
No universal era definition, production-date evidence, originality, significance or collector value is determined.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
