Description
Record the declared source tier of a birthdate used in a longevity study.
Aging research distinguishes participant and informant identities, calendar-month coordinates, time-use exposure and event/censoring status. Proxy responses and missing codes carry different meanings from direct observations. Local record summaries do not establish lifespan, legal status, accessibility or appropriate care.
Record the declared source tier of a birthdate used in a longevity study.
When to use this tool
Use Longevity Record Birthdate Source Tier when checking the stated aging-study record, timing, censoring or support convention.
How to use the tool and how it works
- Enter recordId, birthDateText, suppliedEvidenceTier. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read token. Use the output convention below.
Require nonempty record ID, birth-date text and evidence-tier wording. Encode the ordered triple as JSON text.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| recordId | Nonempty caller-supplied record label; not independently resolved. | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| birthDateText | Nonempty unparsed date wording; no age or chronology calculated. | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| suppliedEvidenceTier | Supplied Evidence Tier | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| token | JSON-encoded ordered tuple or literal token under the convention above; not a database lookup or authentication result. | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"recordId": "R17",
"birthDateText": "1900-01-02",
"suppliedEvidenceTier": "source tier A"
},
"output": {
"token": "[\"R17\",\"1900-01-02\",\"source tier A\"]"
}
}Limitations and assumptions
- Birth date is not parsed, tier not ranked and evidence not authenticated; no actual age or longevity claim 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
Use verified original records and suitable complete research methods; involve qualified health, accessibility or legal professionals for actual care or rights decisions.
