Add metadata to columns
It could be handy to add meta information to the columns of the DataFrame
s passed through the system. Think of information like:
- measurement frequency, important if different time series are merged
- variable type (precipitation, soil moisture)
I can think of several approaches to solve this:
- add the meta data to a columns
MultiIndex
- store meta data in a separate dictionary and pass that around
- store meta data as part of the column name
