Add domains and subtopics

Add your own domains and subtopics, on top of the platform’s built-in ones, so your questions can target them. Today only questions can use a custom domain or subtopic — decisions, pools, acts, missions and AI generation accept platform domains and subtopics only.

Only your dimension’s owner can add or delete a domain or subtopic (not an organisation admin — this is one of the few authoring actions reserved to the owner alone). For a dimension owned by an organisation, that’s the owning organisation’s owner. Admins don’t see the TAXONOMY tab at all.

  1. Open your dimension and go to the TAXONOMY tab.
  2. Under ADD DOMAIN, type a name (2–40 characters, up to 20 domains per dimension), pick a colour, and click + ADD DOMAIN.
  3. The name can’t match a reserved word — a platform domain’s own name, display name or short code, a platform subtopic’s name or id, or one of admin, system, platform, official, dimension, org. The check is case-insensitive and also matches on the slugified form. A duplicate name (yours or the platform’s) is also rejected.
  4. Under your new domain, type a subtopic name (2–40 characters, up to 15 subtopics per domain) and click + SUBTOPIC. The same reserved-word check applies, and the name must be unique across your whole dimension, not just within this domain.
  5. Delete a domain to delete all of its subtopics with it. Deleting a subtopic doesn’t delete the questions or decisions that reference it — they keep the old value, which will no longer resolve as valid.
