Not a replacement for Outlook or Google Calendar, but a library to manage reservations in the following use cases:
- Manage meeting rooms in a company. Users reserve the rooms themselves without an authority confirming/denying their reservations.
- Manage nursery spots. Parents apply for a spot in the nursery for their kid. Someone at the nursery goes through the applicants and decides who gets the spot. Parents may add an application to the waitinglist.
- Manage community facilities. Citizens see the availability of facilities online and call the municipality to reserve a facility. The management is done internally (maybe through an already existing software). A readonly calendar shows the state on the website.
Libres as such does not provide any user interface for reservations. That is the job of other projects depending on Libres.
