I don't know how to ask my question correctly so I'll try to give you an example of what situation I'm unsure about.
An Organizer is holding an event (e.g. a conference) and distributes tickets (maybe for free) but available to the public. He also publishes a timetable for the event on his website so everybody could check what is going on at the event.
- Am I allowed to use this information in my application along with the name of the event (just the information not the given representation) or do I have to ask the organizer if I can show my users this information?
- What if I sell the access to view this information in my application?
By "information" I mean dates/calendar entries (e.g. Event "A" is happening on dd/mm/yyyy at hh:mm:ss in "City"), not editorial content.
I'm located in Germany but the app would be accessible "worldwide".
