An implementation of:
- RCF5545: Internet Calendaring and Scheduling Core Object Specification (iCalendar)
- RFC6868: Parameter Value Encoding in iCalendar and vCard
- RFC7986: New Properties for iCalendar.
This library now covers all of RFC 5545 and some of RFC 7986.
It's already being used in production at https://smos.online and https://social-dance.today.
- Strict RFC Compliance
- Being able to deal with some of other implementors' failures to comply with the spec
