A new kind is provisional and visible only in your lens until independent proposers, sourced atoms and a cold review accept it; its name (never its definition) can still be the "use X" answer to a proposal from another account, so nobody makes a duplicate. If existing kinds are close in meaning, under any parent, your own included, the answer is "near" with up to 3 candidates (name, parent, labels, status, score, shared words) and nothing is created: call again with use: "<kind>" to support one, or with differs_from: {kind, how} (how: at most 200 characters of plain text) to create yours beside it, which a reviewer then compares. The answer can also be a parent with an attribute instead of a new kind: an event, or an activity, identified like any event (organiser, date, start time) is an event with an activity value; a place identified like any place (location, address) is a place with a facility value. Nothing is created then. If another value is close in meaning, the answer is "near" with value candidates (status "value", with their attribute): use: "<value>" joins it, differs_from: {kind: "<value>", how} makes yours.
