# 14 Cypress Lane, Mill Valley (an example)

*A worked example of a JSON article: an invented house whose article carries the card of the invented person who lives in it.*

Everything on this page is drawn from one JSON object. Press **JSON** at the top to see it. Nothing here is real: the house and the person are invented to show how two articles carry each other.

## Who lives here

The line below is an Obsidian transclusion, `![[example-person-dana-reyes|lives here]]`. It draws the person's article as a card, with the facts that article chose to show.

![[example-person-dana-reyes|lives here]]

## One piece of the person

`![[example-person-dana-reyes#facts.work]]` draws one branch of the other article's facts as a JSON widget, read live from that article:

![[example-person-dana-reyes#facts.work|the resident's work, read from her article]]

## The house itself

This is the house's own `facts`, as a widget:

```widget
{
  "type": "json",
  "ref": "#facts",
  "title": "facts of this house",
  "open_depth": 2
}
```

Change one fact without sending the whole article: `PATCH /api/jarticles/example-house-14-cypress-lane` with `{"ops":[{"op":"set","path":"facts.permits[1].status","value":"issued"}]}` and the hash you read in `if-match`.
