so whats the deal with that, im currently using the WaybackMachine to view the pages, is there a reason why they were removed? I cannot find any documentation for either datasource or dataengine on api.kde.org. These two pages are missing, and are available on the internet archive: https://api.kde.org/frameworks/plasma-framework/html/classPlasma_1_1DataEngine.html https://api.kde.org/frameworks/plasma-framework/html/classPlasma_1_1DataSource.html
have these been removed or just moved, and haven't had a redirect set up?
