Item Description

The value of _variant.role specified a role for this variant. Possible roles are null, 'preferred', 'raw data', and 'unsuccessful trial'. A null value for _variant.role leaves the precise role of the variant unspecified. No inference should be made that the variant with the latest time stamp is preferred.

Allowed Value Details
preferred A value of 'preferred' indicates that rows of any categories specifying
this variant should be used in preference to rows with the same key
specifying other variants or the null variant. It is an error to specify
two variants that appear in the same category with the same key as being
preferred, but it is not an error to specify more than one variant as
preferred in other cases.
raw data A value of 'raw data' indicates data prior to any corrections,
calculations or refinements. It is not necessarily an error for raw data
also to be a variant of an earlier variant. It may be replacement raw
data for earlier data believed to be erroneous.
unsuccessful trial A value of 'unsuccessful trial' indicates data that should not be used
for further calculation.
