KWeatherCore: https://invent.kde.org/libraries/kweathercore is a library for
querying weather forecast data.
During the development of KWeather, we found the need to have a weather library.
KWeatherCore is the result of extracting weather data fetching code from
KWeather.
I think having a dedicated weather library can serve the following propose:
- simplify the KWeather code
- easier to develop a weather daemon
- potentially less code duplication across KDE
Many of you may have already seen my previous email to kde-devel mailing list.
Thank you for your constructive suggestions. Here are something I want to
clarify:

The end goal is a daemon indeed, but we want to build the daemon upon the
library. This would give us flexibility
in the future if we don't want a daemon. At least KWeather and other projects
can still benefit from the code.

I admit there are some overlapped functionalities. But KWeatherCore isn't
designed as a weather data provider as Weather DataEngine.
Instead, it's trying to be the building block of weather related
applications. KWeatherCore saves you the hassle of
dealing with APIs, getting locations and converting timezone. You can build a
daemon with it, or you can
use it in your applications. For example, KItinerary and KWeather use the
same weather API, but don't share code.
That means two code base to maintain. Regarding the dynamic nature of online
APIs, it's better to have one library,
so other applications don't need to be worried about their APIs being
depraved, and they aren't able to update it in time.
Though not currently implemented, KWeatherCore does intend to have weather
alerts added. We hope it can be done in this Sok

With this bit added, then the work on weather daemon can be started.
