Targets and thresholds · The target · Element
The history
How the target has been met over time.
The part
What it is
Met every period suggests it is too low; never met suggests it was set without reference to what is possible.
The pattern is more informative than any single period and takes no effort to keep.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
