. . . . "This is a data-related requirement that is a pre-requisite for the 'accuracy' of metadata that FAIR principle (R1) refers to. This requirement is borrowed from one of the key Tidy Data Principles, which states that each column/field should be a single variable. This prevents the often seen scenario in structured data whereby a single column header might carry values for more than one variable. For example, 'temperature_screening', 'temperature_followup', each column implicitly carries the value for a visit variable and a value for an observation temperature in this case. This indicator therefore requires the data manager to split these variables into two fields: One per variable that is a field for temperature and a field for visit. This is a pre-requisite to DSM-2-C5 and DSM-2-C6 since each Dataset Field is expected to control its terms and create a local dictionary. Unless individual concepts are reported per Dataset Field it will not be possible to find suitable terms that can later be standardised for level 3." . . . .
