External Software

Some external software are added in the Data Node to complement Nextcloud.

1. Photoprism

Currently Photoprism is installed in the Data Node to provide an AI driven multimedia album for your Private Cyberspace.

The files on Photoprism are accessed from within Nextcloud under the photoprism directory using via the WebDAV external storage with the following setting by default:

  • Encryption - Disabled
  • Preview - Disabled
  • Sharing - Disabled
  • Check Changes - Once every direct access
  • Mac NFD - Disabled
  • Read Only - Disabled

Note the default processing delays in Photoprism:
PHOTOPRISM_AUTO_INDEX - default 5 minutes.
PHOTOPRISM_AUTO_IMPORT - default 3 minutes.

Further work:

  • turn off requirement for review in order to show image in main view (by default).

1.1. Alternative

The following Nextcloud Memories Plugin Set can be used instead of Photoprism to provide media album function.

  1. Mosquitto

MQTT server for messaging

OCC Commands

Data Node Search

Currently supported data sources:

  2. Calendar
  3. Contacts
  4. Deck
  5. Files
  6. Talk


You can type the following into the search input box:

  • word will try to find posts with that word

  • “exact phrases” will try to find the term inside the quote marks. This allows looking only for direct matches, such as "look at my cluckers" to find posts explicitly telling you to look at someone’s cluckers.

  • -exclude will exclude the term prepended by a minus sign. This allows filtering out certain terms, such as animals -cats to find posts about animals without posts about cats.

  • +include will include the term after the plus sign. This allows searching for multiple terms that must be included, such as cat +dog to find posts about both cats and dogs.

the search syntax is the same as the one used on the hub server.


  • test nextcloud help
    will return all your files containing test OR nextcloud OR help in their path or content.

  • +test nextcloud help
    will return all your files containing the exact word test and that might contains nextcloud OR help in their path or content.
    For example, the file in the folder help/ that contains the string test the opensource project nextcloud or test anything or testing nextcloud but not testing anything.

  • +testing nextcloud -"testing nextcloud"
    will return all your files containing the exact word “testing” and that might contains nextcloud but does not contains the exact string testing nextcloud

  • nextcloud -test
    will return all your files containing nextcloud but does not contains words starting with test

Additional Servers

2. File Server
