Dear Éamonn, all,
I am currently using a dataset with density and biomass data, and was
wondering within what timeframe the terms organismQuantity and
organismQuantityType would be adopted and whether these terms are
already recognised in the IPT2.2 pre-release version.
If this is not the case, I would appreciate your advise on the best
practice to include such data at the moment. I was either thinking to
(mis)use the inidividualCount field or use the MeasurementOrFact
extension. What would you recommend?
Thanks for your advise!
With best regards,

The value of organismQuantity is a number or enumeration, e.g., “27” for an organismQuantityType “individuals”, “12.5” for an organismQuantityType “%biomass”, or “r” for an organismQuantityType “BraunBlanquetScale”.

The value of organismQuantityType (i.e., the entity being measured) is expected to be drawn from a small controlled vocabulary with terms such as “Individuals”, “%Biomass”, “%Biovolume”, “%Species”, “%Coverage”, “BraunBlanquetScale”, “DominScale”. Examples when combined with organismQuantity values: + on DominScale; 5 on BraunBlanquetScale; 45 for %Biomass.
