Date monthly (YYYY-MM-01) |
|
Description
:
|
Date of a month (the day is not relevant and set by default to the 1st of the month). The format is YYYY-MM-01.
This format can be used to indicate that values have been aggergated (average, sum, mean, etc) over a month. More details of the aggregation method are annotated in method steps of the individual attribute or in the title or abstract of the dataset.
This format can also be used to indicate that only the month of an event is known. More infromation have to be added to the dataset description. |
