Question: Most of our data is released under the terms of the CC-BY license, but some data sources have other terms. Is there a good way for us to embed licensing information and show it on the download page?

I think the "We would be happy for you..." would just need to be conditional on source, so by default it would say "under the terms of the Creative Commons Attribution license", but for other sources it would say the data is provided by [some source] under [some terms].

what about adding a field to the signal description at https://docs.google.com/document/d/1RLy4O-gtACVjLEVD_vxyPqvp9nWVhqEjoWAKi68RKpg/edit#heading=h.oxebzdy7nl8w which can cover those cases?

see also new suggestions in the google doc

[sgratzl]

current state:

• renamed Data source to "Cases and Deaths"
• add see also with the links from the description
• incorporate the credit section from the description field in google doc

Do we expect the wget command to work on the existing version?

wget --content-disposition "https://delphi.cmu.edu/csv?signal=doctor-visits:smoothed_adj_cli&start_day=2020-10-24&end_day=2020-11-24&geo_type=county"
