Set item datetime or start_datetime/end_datetime fields #35

Description

@Hneuschmidt

The STAC best practices document mentions that data in datacube format should set the start_datetime and end_datetime fields to the start and end of the period the cube is covering. The datetime field should be set to a representative date, if possible.

Currently (as of 0d108ad):

  • start_datetime nor end_datetime are not set
  • datetime is set to the processing date

To set start/end_datetime we would need to implement some logic to extract this information from the cube, as it is only implicitly encoded in the asset file name metadata.

The datetime should likely be set to null. I don't see an obvious candidate for a representative date for FORCE datacubes. This is only possible, when start and end datetime are set.
