I wonder if the unit should be controlled by a predefined code list. Otherwise we will have a multitude of units for the same quantity type, e.g. W, kW, MW etc. for power.

Alternatively, in stead of unity type, allowing selection of a quantity type like "time", "length", "area", "power", "currency" etc. where the unit is predefined to a non-prefixed unit, correspondingly to "s", "m", "m2", "W", "unspecified".

I saw a RFC. Is someone working on that?
Semantic annotation of formulae that contain units is part of my PhD topic... therefore I'm very interested in that topic and open for potential contributions.

Status update: We have just released the first version of the quantities data type on It does not yet support units.

@Physikerwelt: feel free to get in touch with me via email :)
