OpenOLAT calendar events can have links to course elements, library entries or other links. Those links can only be used within OpenOLAT because they are store using an XProperty.
Interestingly there exists also an UrlPropery which is for exactly this purpose. The idea is to move to the UrlProperty so that other ical clients can display the links when having the calendar mounted with external tools.
- Event links are stored using UrlProperty (maybe in addition to the XProperty if this has benefits or is more stable for internal use)
- Testing how it behaves with Mail.app (OSX), Outlook (Windows), iOS calendar App und Android caledar App.
