Discussion about Concept of Recurrence Rules
By looking for concepts of recurrence rules for the BFR-API I would prefer to use the RRULE concept known from iCal. I started the API deduction here. Here are some examples. This RRULE concept seems to be flexible and common. Also there seem to be Python and Django packages for it:
python3-dateutil/testing,testing,now 2.8.1-4 all [installed,automatic]
powerful extensions to the standard Python 3 datetime module
python3-django-recurrence/testing,testing 1.10.3-1 all
Django utility wrapping dateutil.rrule (Python3 version)
In context of the LOHROthek backend I'm interested, why this RRULE is not used for the airtime templates @prelle? Is it a too complex solution?
