12TA Your advice please... What works?
12TA Let's assume the data should be kept Wiki-side in an events namespace rather than in an external cloud service.
I had the same approach and couldn't find anything out-of-the-box in DokuWiki. I guess, calendars require a lot of webdesign and styling. A good starting point is the yearbox plugin, which provides the backbone for any calendar. For styling and such you can use conf/userscript.js
and conf/userall.css
or (re)write your own plugin on top of yearbox, like I did. Cheers!
