### Required
- [`name`](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-name): The events title.
- [`attributedTo`](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-attributedTo) or [`actor`](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-actor): Mobilizon uses actor for the user profile and attributedTo for the group. But as `actor` being part of an object is not part of the ActivityPub spec, solely using `attributedTo` might preferred if they are similar.
- `id`: This is also used for the `url`.
- [`name`](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-name): The events title.

### Attachment/Banner-image handling
Mobilizon currently expects all images to by within `attachment` and to be an `Object` of type `Document`. It first looks for an object where the `name` is equal to `Banner`. If that is not found it uses ´attachment[0]`.

- [`location`](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-location): The subkey [`address`](https://schema.org/address) is accepted, both as [`PostalAddress`](https://schema.org/PostalAddress) and pure text.

- [`summary`](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-summary) The summary is only used when no content is supplied.
### Not used
- `attributedTo`/`actor`: Gancio does not support fetching event other than by receiving a `Create` or `Update` activity (TODO: what about `Announce`), the actor is always just fetched from the activity, not the object within.
### Handling of visibility
Currently Gancio does not seem to handle any visibility or replies-policy options. It sets all remote events it received to the internal `is_visible` to `true`.
