The two crucial properties for this are:
stratification_flag: a string, allowing us to identify the stratification
stratification_timestamp: timestamp indicating when the sample was selected for stratification
These properties should be exposed both via OGC Features API, and in Parquet files.
As elaborated here: https://worldcereal.github.io/worldcereal-documentation/design/reference_data_module.html#sample-stratification-in-the-rdm we would like to add properties that allow to mark a sample as being selected by a specific run of a stratification algorithm.
