Schema

Schemas

Each dataset consists of the relevant metrics tied to the primary keys describing location and time. Those metrics are described in more detail here.

Location details are delivered as a file/table on the side or optionally embedded on any dataset. For bulk deliveries we recommend receiving this on the side, while for smaller extracts it can be handy to receive further location details inline. See the different Location schemas here.
