The PDS4 master schema defines a set of unit classes - related units of measure - to be used for defining label attributes in all dictionaries. Following is a list of these unit classes and the standard values allowed for attributes with that unit type. Case, spacing, and abbreviation all count when it comes to matching values.


As of 2017-01-11, this page has been updated for release 1.7.0.0 of the PDS4 Information Model.
