Ownpad — Etherpad and Ethercalc links in Nextcloud
Ownpad is a Nextcloud application that allows to create and open Etherpad and Ethercalc documents. This application requires to have access to an instance of Etherpad and/or Ethercalc to work properly.
Note that the documents are only stored with your Etherpad/Ethercalc service provider; no copy is kept on Nextcloud. As documents are created this way Nextcloud is not responsible for the documents security, e.g. anyone with access to the Etherpad/Ethercalc service can access your document.
In order to make Ownpad work, go to the configuration panel (Settings / Admininstration / Additional Settings) and fill in the necessary data within the “Ownpad (collaborative documents)” section.
Set a Etherpad Host:
To be able to process the document, a must configure a Host. Additional public host provider more public Host-Provider
Afterwards, the “pad” and/or “calc” items will be available in the “+” menu from the “File” app.
Unfortunately, apps can’t declare new mimetypes on the fly. To make
Ownpad work properly, you need to add two new mimetypes in the
mimetypemapping.json file (at Nextcloud level).
To proceed, just copy
/config/mimetypemapping.json (in the
config/ folder at Nextcloud’s
root directory; the file should be stored next to the
file). Afterwards add the two following lines just after the “_comment”
"pad": ["application/x-ownpad"], "calc": ["application/x-ownpad"],
If all other mimetypes are not working properly, just run the following command:
sudo -u www-data php occ files:scan --all
Create access restricted pads
Ownpad supports communication with the Etherpad API for access restriction (so called protected pads). This support is considered experimental due to work in progress; some features are still missing. See the TODO.md for details.
Protected pads need to be accessed via Nextcloud in order to gain access privileges.
In order for this to work, you’ll need to enter your Etherpad API key
within the Ownpad settings. You can find your API key in the
APIKEY.txt file of your Etherpad instance.
In addition you’ll need to host your Etherpad and Nextcloud instances
under the same domain. For example, you can host your Etherpad in
pad.example.org and your Nextcloud in
cloud.example.org. For this
example, you’ll have to set the cookie domain to
the Ownpad settings.
If you want to create truly private pads, you have to dedicate an
Etherpad instance for Nextcloud running both with HTTPS. You will then configure Etherpad to
restrict pad access via sessions and pad creation via the API.
For this, you have to adjust your Etherpad configuration file
settings.json) as following:
"requireSession" : true, "editOnly" : true,
