Overview
...
The unit conversions id to convert from the (internal) units to the display units. This id should be available in the UnitConversionsDescriptors. Only required when a displayUnit is specified for a parameter group
...
The unit conversions id to convert from the units specified in config files to the internal units for this parameter. This id should be available in the UnitConversionsDescriptors. Only required when a user unit is specified for a thresholdValuesSet, validationRuleSet or ratingCurve
...
Optional cell method (for time dimension) as defined in the netcdf CF convention. This is currently only used for export to netcdf files. See http://cfconventions.org/Data/cf-conventions/cf-conventions-1.6/build/cf-conventions.html#cell-methods
tideNumberParameterId
SINCE 2022.02. The parameter of a time series (set) is replaced (behind the screens) with this parameter to find the tide number

In case there is no timeseriesset for the combination of parameter and location, the nodes will be grayed out:
Enumerations
Parameters can also be defined as enumerations. Then there will be a set number of possible values with a specific label. The value will be stored in the database, the label will be shown in the GUI.

Parameters in csv format
It is possible to define parameters in a csv file. By using %% can be referred to the content of the columns in the csv file. For example:
