C17 · Reference edition 2026.11
Temporal notes — Layout and sequence
An impression can change during an observation. Record onset, development and persistence as separate descriptions where useful.
Scope and purpose
Place the relevant elements in a visible order before completing the record. A diagram should distinguish position from sequence and should preserve the orientation used in the written notes. Review the example for a practical way to make the relationship explicit.
Working notes
This atlas connects descriptive vocabulary, observation context and reference-sheet design. All example records are synthetic and exist to explain a method of documentation; they do not represent tested batches, product ratings or scientific results. The diagrams are original editorial graphics. Descriptions of perceived character are kept separate from ingredient, origin, health and certification claims. Read definitions and scale anchors before comparing records.
Practical example
Use a three-stage timeline rather than a single unexplained duration value.
