 prior to owncloud9 there was a sync script which did exactly that. unfortunately it no longer works with oc9 and the developer has posted that he won't fix it, so we need a new solution.

+currently i am using [[https://vdirsyncer.readthedocs.org|vdirsyncer]]. to install in ubuntu 16.04 i did this:
   apt-get install libxml2 libxml2-dev libxslt libxslt-dev zlib1g python python-virtualenv python-pip
-  virtualenv /opt/owncloud/vdirsyncer
+  pip install pipsi
-  export CPLUS_INCLUDE_PATH=/usr/include/libxslt/:/usr/include/libxml2/
+  pipsi --home /opt/owncloud/ install --python python3 vdirsyncer
-  /opt/owncloud/vdirsyncer/bin/pip install vdirsyncer
+now it's time to configure your vdirsyncer.. in my case i wanted to sync a html read-only source (ical format) to owncloud. here is my config file:
+<code>
+[pair photokiste]
+a = photokiste_crm
+b = photokiste_owncloud
+collections = null
+conflict_resolution = a wins
+[storage photokiste_crm]
+type = http
+url = https://www.source-server.com/ical.ics
+[storage photokiste_owncloud]
+type = caldav
+url = https://my.owncloud.server/remote.php/dav/calendars/username/calenarname
+username = myuser
+password = mysecret
+</code>
+the owncloud calendar name can be viewed by hovering over the calendar. it will appear as mouse pointer tooltip.
+one thing on the ical format.. i used a library called ''PHP iCalWriter'' which i generated the ical source file with. as it turns out, PHP iCalWriter writes an different DTSTART and DTEND field for whole-day-events than what owncloud accepts. i have no idea who's write and who's wrong, but since i PHP iCalWriter is open source and it is already quite an old version i am using i decided to simply modify it. make sure, that your ical file contians a DTSTART and DTEND that look like this for whole-day-events (that is, events where the start and end date does not contain a time):
+  DTSTART;VALUE=DATE:20160903
+and a line like this for date + time start and end dates:
+  DTSTART:19701025T030000
+(PHP iCalWriter never added the ;VALUE=DATE: portion).
+this might be an onwcloud problem, as owncloud exports the "wrongly" specified events but it does not show them on the web-interface.. so maybe the web ui is just messing this up..
+once the config file is written, vdirsyncer can be run through cron or manually like this:
+  VDIRSYNCER_CONFIG=/opt/owncloud/vdirsyncer/bin/photokiste.conf /opt/owncloud/vdirsyncer/bin/vdirsyncer sync
+that's it :) .. theoretically vdirsyncer should also support two way sync, but i haven't tried that..  however they seem confident in their solution so it might be worth a try even for two-way syncing :)
