Computer/software agents used in the download, for example, R 4.3.2, eurostat 4.0
The user who has downloaded the data
If applicable, the permanent URL of the data that was downloaded, if not, the url of the data
If a chain of provenance is provided at source, retain the provenance, for example, some datasets in the Eurostat data warehouse arrive without modification from the European Environmental Agency.
What type of metadata should be preservered
