Attach an explicit calendar determination date and attribution to a herbarium record without verifying an identification.

Description

Label a specimen's recorded determination date and determiner wording.

Botanical observations distinguish specimen provenance, sampling states, germination records, image area and category vocabularies. Excluded observations differ from failed germination, and a pixel-area calibration must use an area ratio rather than a length ratio. Source-qualified labels preserve reported identifications without confirming them.

Label a specimen's recorded determination date and determiner wording.

When to use this tool

Use Herbarium Determination Date Label when you already have specimenId, determinationDate, determinerWording and need to label a specimen's recorded determination date and determiner wording.

How to use the tool and how it works

  1. Enter specimenId, determinationDate, determinerWording. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read label. Use the output convention below.

Require specimenId/determinerWording nonempty and a real UTC date; append the date and wording.1

Limitations and assumptions

  • No specimen, taxonomic determination, person identity, provenance or name usage is authenticated.
  • 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

Inspect the original specimens, observation logs, calibrated images and taxonomic sources. Use the complete survey or experimental method for biological interpretation; local fractions and record checks do not infer unobserved states or mechanisms.
