1.0.0-rc1: Please add relations of ISQBaseQuantites to the corresponding SIBaseUnits

[markdoerr]

Dear @jesper-friis and @emanueleghedini,

in the current 1.0.0 release candidate there is no relation between the ISQBaseQuantites to the corresponding SIBaseUnits,
which is unfortunate, since it would allow a lot of applications, which are currently not easy to realise.

Why would that be important ?

If the quantities of a measurement are known (which is the common case), one could derive / query the corresponding SIBaseUnit.
This extra linkage would make the unit definitions much more useful in practical applications, since it allows direct access to (standard) units from measurement descriptions without the need to specify in which standard unit the measurement would be expressed.

How could this look like ?

Example:

emmo:Length emmo:hasSIBaseUnit emmo:metre

etc.

Dear @markdoerr
In the the current version of EMMO is the quantity length is related to the unit metre via the following relations:

emmo:Length emmo:hasMeasurementUnit some emmo:LengthUnit
emmo:Metre rdfs:subClassOf emmo:LengthUnit

This kind of relations between quantities and units are general and not restricted to base quantities.

Doesn't this catch the relation you are asking for?

When the quantity is a ISQ base quantity, there will only be one subclass of the general unit class (emmo:LengthUnit in this case) that is a SI base unit.
