Hi!
I am a particle physicists, so I'm interested in using the Wikidata
project in order to keep physical constants, like the mass or lifetime
of the neutron, in sync between different articles. In this use case it
will be important to have not only the possibility to store and retrieve
the value of this constant, together with the reference to the data
source, but also the uncertainty. Would it be possible to include a
special data type for such constants where the value, the total
uncertainty and the unit of measurement can be stored together with the
reference (the additional storage of statistical and systematic
uncertainty would be nice, but not necessary).
Best regards,
Alexander
