=== Add Units to the Mix
As mentioned earlier, parameter catalogs should be able to represent quantities, not just bare numbers.
See https://onlinelibrary.wiley.com/doi/full/10.1002/spe.2926[Unit of measurement libraries, their popularity and suitability] for a systematic account of open source solutions in the this area.
Java provides an extensive framework to deal with quantities and their units defined in https://docs.google.com/document/d/12KhosAFriGCczBs6gwtJJDfg_QlANT92_lhxUWO2gCY/edit#heading=h.6698n7erex5o[Java Specification Request (JSR) 385].
The reference implementation for this framework is https://unitsofmeasurement.github.io/indriya/[Indriya]. Demos of its usage can be found at https://unitsofmeasurement.github.io/uom-demos/[].

The symbols for defining units follow SI and other standards, including decimal prefixes like `m` for Milli or `G` for Giga as well as derived units, that is: `mV`, `GV` or `kW·h/m³` are all valid unit definitions. This is all documented well in the resources mentioned at the top of this section, but for convenience, a table with valid units, including some specific units for urban simulation, is compiled in link:UnitsExamples.md[].
If a unit symbol cannot be interpreted, this error is not already detected while generating and compiling code from model, but not before runt time when the application tries to create the default value. In that case, you will see an error message like this:
