This project is funded (likely 04 - 10/2018, two persons) via the [prototype
fund](https://prototypefund.de/project/robur-io/).

[Wikipedia](https://en.wikipedia.org/wiki/Calendaring_software) says:
calendaring software is software  that minimally provides users with an
electronic version of a calendar. Additionally, the software may provide an
appointment book, address book, and/or contact list.

[CalDAV](https://en.wikipedia.org/wiki/CalDAV) are the calendaring extension to
WebDAV (a HTTP-based protocol for data manipulation).

We plan to implement a CalDAV server based on MirageOS.  The data is stored in a
git repository by using [irmin](https://github.com/mirage/irmin).  We will do
interoperability testing with widely used clients (Android, Thunderbird, Apple
iCal).

Expect more updates of this project once it starts.
