Sam,
Don't confuse two things. -1- A measument is a measurement. It is raw data. -2- An interpretation of raw data by a human or agent or Archetype transforms this in Information. Any interpretation is a view on raw data plus a (subjective) interpretation. And systems should show this and the author of this subjective interpretation. Boundary problem: A radiologist interterprets a complex x-ray. The x-ray is the raw data. The radiology note is the attributable view on raw data plus the subjective interpretation. Now this note is sent to a GP. At the receiving GP system this note is treated as raw data. Measurement. After acceptation by the GP and submission this raw data to the record it can be used to interterpret it. Etc, etc. The delta-flag is not an attribute to data but a subjective interpretation recorded in a subjective view.
