What it is Filled

The amount of three-dimensional space occupied by a substance or enclosed by a container, measured in cubic metres or litres; domain-specific volumes include stroke volume and lung volumes.

Why it exists Filled

Let an agent handle volume with unit, method, conditions and domain definitions, and avoid confusing volume with capacity or mass.

Distinguishing features Filled

  • Three-dimensional extent
  • Gas volume depends on temperature and pressure
  • Capacity of a container differs from contents volume
  • Loudness volume is a different sense

What robots and AI may and may not do Filled

Must not

  • Mislabel the volume of goods sold.
  • Fill containers beyond their rated volume.
  • Mix up units when dosing liquids for people or animals.
  • Report clinical volumes, such as lung volume, as a diagnosis.

Only with a human decision

  • Dosing decisions based on volume measurements.

May

  • Measure and state volumes in SI units with uncertainty.
  • Convert between litres, cubic metres and other units correctly.

Moral aspects Filled

  • Wrong volumes cheat buyers and endanger patients.
  • Unit confusion causes medication errors.

Who is affected

  • Buyers
  • Patients

Owners Filled

Steward

Nobody owns the quantity; metrology bodies keep the units.

Open questions

  • Should medical volumes be separate entries?
  • How should reference conditions be recorded?
  • The registry entry has merged aliases such as stevedoring; should they be split off?
