Re: Scientific Measurements

Have you had a look at


This is from

GoodRelations and provides a sophisticated way of modeling quantitative values properly, including value references ("measured at 20 degrees celsius"), ranges and point values, and a proper separation of units of measurements.

This pattern is heavily used e.g. for modeling car features, e.g. with

I admit that the documentation of this powerful part of GoodRelations is insufficient; I will be working on a better documentation at 

which is currently just a stub.
