Implementation of seasonal calendar "Seasonal Foods Calendar"

[maninthemiddle01]

If it's not already implemented would it be possible to implement the database of the seasonal calendar of this project:
https://github.com/seasoncalendar/seasoncalendar

There the developer states:
The database file assets/db/foods.db contains all food information and their respective sources. You can open the file e.g. with the official SQLite DB Browser. Please note that the data concerning foods' availability partly stems from lebensmittellexikon.de and thus is not subject to the GPL license. I kindly ask you to contact me before re-using the availability data (columns starting with 'av' from the file assets/db/foods.db).

Hmm, I can't import copyrighted data into the app.

Are you missing a specific fruit or vegetable?

Also, when I researched the data for the seasonal calendar I tried to keep it rather general for maximum compatibility with subregions and recipes. I had a look at the lebensmittellexikon.de calendar and they have for example four different kinds of savoy cabbage (that I haven't even heard of yet ;)) I don't think it would be helpful to go into this level of detail since the focus is on cooking and not gardening and these special kinds of veggies would probably never be mentioned in recipes.
