Description

We describe an effort by representatives from the metadata standards groups of HAPI, SPASE, and ISTP Metadata Guidelines to develop a recommendation for the representation of scientific units in metadata. The recommendation is “Some metadata models in Heliophysics do not have a constraint on unit strings (that is, a standard has not been chosen). Our recommendation is that if a standard is used, it should be VOUnits.”
