Get lastUpdated date of a dataset

[Davide Marcon]

Good morning,
via Python and with the pandasdmx library I am trying to access the metadata of the dataset https://esploradati.istat.it/databrowser/#/it/dw/categories/IT1,Z0920ENV,1.0/ENV_WATER/DCCV_CONSACQUA/IT1,12_60_DF_DCCV_CONSACQUA_1,1.0

Specifically, the date of the last survey does not seem to be present in the metadata. For app development I would need to know if I need to download the updated dataset before downloading it entirely. In fact, I would only download it if it contains new data.

Specifically this is what I find

{'header': <Header>
  id: 'IDREF211'
  prepared: '2024-08-20T19:40:02.543637+02:00'

Does anyone have more information about this?

Many thanks
