Open Web Calendar Stack
Aggregate public and private web calendars
The Open Web Calendar stack is an open-source set of Python libraries and programs which read and write calendars based on the iCalendar standard. The Open Web Calendar displays a highly configurable website that can be embedded to show a calendar. Currently, ICS URLs are supported and a goal is to also support CalDAV.
Amongst the used libraries is the popular icalendar library to parse and write iCalendar (RFC5545) information. This cornerstone of Python's ecosystem requires some work to be up-to-date with common practice such as updating the timezone implementation. The updates to the icalendar library will be tested and also pushed up the stack to the Open Web Calendar.
The recurrence calculation of events is done by the python-recurring-ical-events library. Changes to icalendar will be tested against this library to find compatibility issues. As the iCalendar standard has been updated, recurrence calculation is affected, too. These updates need to be evaluated and possibly implemented for both icalendar and the recurrence calculation.
By implementing changes at the base, the whole stack is improved. We can use the Open Web Calendar project to make sure that possible transitions and updates are mapped out and communicated to other projects in the ecosystem. Improving a FOSS solution thus spreads the accessibility of iCalendar.
