Appendix — Compound Unit Labels (Informative)
AEON GP Measurement v1 permits compound unit labels in the unit attribute.
Compound unit labels are treated as opaque identifiers and are not parsed or interpreted by AEON.
Example:
speed@{unit="m/s"} = 12
acceleration@{unit="m/s^2"} = 9.81
density@{unit="kg/m^3"} = 1000
bandwidth@{unit="Mb/s"} = 100Interpretation
Compound unit labels may describe derived measurements such as:
| Unit | Meaning |
|---|---|
m/s | meters per second |
m/s^2 | meters per second squared |
kg/m^3 | kilograms per cubic meter |
Mb/s | megabits per second |
AEON does not interpret or validate these expressions.
They are treated as plain unit identifiers.
No Grammar Requirement
AEON GP Measurement v1 does not define a formal grammar for compound units.
Characters such as the following may appear within unit labels:
/
*
^
-Example:
power@{unit="kg*m^2/s^3"} = 120Processors, schemas, or profiles may optionally define stricter rules if needed.
Recommended Practice
When compound units are used, they should follow widely recognized conventions (such as SI notation) to improve interoperability.
Example:
flow_rate@{unit="m^3/s"} = 4Summary
Compound units are allowed because:
they are common in scientific and engineering data
they require no additional language features
they remain consistent with AEON’s rule of opaque value labeling
AEON therefore preserves compound unit labels exactly as written.
