Nested tags

Tags can be nested. For example:

  • #inbox/to-read
  • #life/friends/bob
  • #books/tlp
  • #tech/db

Nested tags will be visualized as a tree in the Graph view.

Global tags


This is an experimental feature.

A global tag is a shared place for a group of people to publish notes. It has the form

Planet relies on DNS to retrieve configuration for global tags. For example, the configuration for the global tag should be stored in the TXT record of The record content is a list of space-separated key-value pairs that looks like:

planet-allow=alice,bob planet-title=VGVzdCBHbG9iYWwgVGFn planet-desc=VGhpcyBpcyBhIGRlc2NyaXB0aW9u
  • planet-allow: A comma-separated list of usernames that can write to this tag.
  • planet-title: Base64-encoded title. VGVzdCBHbG9iYWwgVGFn is encoded from Test Global Tag.
  • planet-desc: Base64-encoded description. VGhpcyBpcyBhIGRlc2NyaXB0aW9u is encoded from This is a description.

Configuring a global tag

Step 1: Enable DNSSEC for your domain

DNSSEC is an extension to DNS that provides cryptographic authentication of records. Planet requires DNSSEC for global tag domains.

Go to your DNS provider and follow their instructions to enable DNSSEC.

Step 2: Add the TXT record

The format of the TXT record is described above. Go to your DNS provider and add the record:

global tag txt record

Wait for a few minutes and the configuration should come into effect.
