+# Konzept
+
+## Notizen
+
+- Kalender sollen unabhängig von Nutzern bestehen können
+- Zugriffs-Stufen
+  - `none`: kein Zugriff
+  - `view`: nur lesend
+  - `edit`: lesend und schreibend
+  - `admin`: kann alles (auch Kalender löschen)
+- einem Kalender können beliebig viele Nutzer zugeordnet werden, die jeweils bestimmte Zugriffs-Stufen zugewiesen haben
+- Veranstaltungen bilden keine eigene Domäne
+- es gibt verschiedene Arten von Quellen:
+  - lokal
+    - enthält Veranstaltungen
+  - caldav
+    - enthält keine eigenen Veranstaltungen
+    - sollte read-only- und read/write-Modus haben
+- nach dem Anmelden sieht man eine Kalender-Ansicht mit folgenden Kalendern kombiniert angezeigt:
+  - öffentliche Kalender
+  - nicht öffentliche Kalendar, bei welchen man mindestens Lese-Berechtigung hat
+- öffentliche Kalendar können ohne Anmeldung betrachtet werden, jedoch nur mit einem schwer bis gar nicht erratbaren Link
+
+
+## Zugriffssteuerung
+
+Es gibt folgende Zugriffsstufen :
+
+- `none`: kein Zugriff
+- `view`: nur Lese-Zugriff
+- `edit`: Lese- und Schreib-Zugriff
+- `admin`: Lese- und Schreib-Zugriff + Bearbeitung von Kalender-Eigenschaften
+
+Zur Bestimmung welche Zugriffsstufe ein Nutzer auf einen Kalender/Termin hat, werden drei Werte betrachtet:
+
+- Öffentlichkeit des Kalenders (`public`)
+- Standard-Zugriffsstufe des Kalenders (`default_level`)
+- dem Nutzer zugewiesene Zugriffsstufe für den Kalender (`attributed_level`)
+
+Diese Angaben fließen in folgende Formel ein:
+
+```
+access_level = max(
+    (if public then 'view'  else 'none'),
+    (if (attributed = NULL) then default_level else attributed_level)
+)
+```
+
+… wobei die Ordnung der Zugriffsstufen der oben ersichtlichen Reihenfolge entspricht.
+
+Einzeln aufgeführt ergibt das:
+
+| public | default level | attributed level | result |
+|-- |-- |-- |-- |
+| no | none | - | none |
+| no | none | none | none |
+| no | none | view | view |
+| no | none | edit | edit |
+| no | none | admin | admin |
+| no | view | - | view |
+| no | view | none | none |
+| no | view | view | view |
+| no | view | edit | edit |
+| no | view | admin | admin |
