Following http://doc.silverstripe.org/doku.php?id=recipes:extending_the_event_calendar and Uncle Cheese advices we extended event_calendar to fit our needs as seminars module. So, each seminar is described by SeminarEvent [extends CalendarEvent] (say "Analysis Seminar") contains many talks, each talk described by SeminarDateTime [extends CalendarDateTime] contains datetime, location, title of the talk, .... SeminarEvent also has a general content describing purpose of seminar, organizers, blah blah. So far so good.
Our problem is that feed from seminar lists this general info rather than talks specifics. So question:
How extending event_calendar we can customize feed?
Thank you in advance. What we have and 99% happy with
