Re: Scientific Measurements

Alex,

Hmm...It looks like we already have QuantitativeValue but that's about it.

http://schema.org/QuantitativeValue

But that Type stems from eCommerce & Trade ... but it's all primarily based
on UNECE codes... and those happen to have Measurements defined even
scientific ones if you dig deep enough in it.

See the "master list" here:
http://www.unece.org/cefact/xml_schemas/index.html  and scroll down and you
will see the UNECE MeasurementUnit sections and others.

Those sections should help you out a bit.

But we probably still need to have someone from the scientific community go
through the "unit of measurement" points to make sure that Schema.org
QuantitativeValue has what it needs or perhaps create additional Types to
handle "measurements" sufficiently enough for SI work and for your purposes
that fall outside the common Trade and eCommerce use cases.
