    8 * `Identifier`: this is the standard name that the loading functions require as argument when we set the `standard.vars` argument to `TRUE` (see the [wiki:SpecsEuporias/RPackage/Functions defined functions]).

    99* `Standard_name`: standard name of the variable as defined by the CF convention.

The dictionary also provides additional metadata often not explicitly declared in the datasets, regarding the ''time'' aggregation of the dataset (often referred to as the ''cell method''). This includes the fields `time_step`, which is merely informative, and describes the time interval between two consecutive values, and the `lower_time_bound` and `upper_time_bound`, which are the values that should be summed to each verification time to unequivocally delimit the time span encompassed by each value.

    36 The dictionary is a comma-sepparated text file (csv), that by default is identified with the same name than the dataset, and the extension ''.dic'', and stored in the same directory than the dataset, although its name and location can be other if adequately specified in the loading functions by the argument `dictionary`. The dictionary must be created  ''"by hand"'' by the user, because it requires some ''a priori'' knowledge about the characteristics of the data stored in the dataset, that can be partly obtained using the function [wiki:SpecsEuporias/RPackage/Functions#dataInventory dataInventory]. The columns of the dictionary are next described:

    60 Note that column names matter (not so their relative order), because the data load functions will perform the conversion of the variables to the standard format by finding the corresponding values by the name of the columns. The [https://www.meteo.unican.es/trac/meteo/attachment/wiki/SpecsEuporias/meteoR_v1_0.zip meteoR] package includes some dictionaries, and specific examples are given in the [wiki:SpecsEuporias/RPackage/Examples Examples section]
