# JSON Feed RSVP Extension This extension adds a new, optional `_rsvp` field on each Item in a JSON Feed document, to contain additional metadata fields pertaining to events. ## ## Example ```jsonc { "version": "https://jsonfeed.org/version/1.1", // ... "items": [ { // ... // An RSVP entry MUST contain an `external_url` pointing to the event // the RSVP is in response to "external_url": "https://example.com/example-event-document", // The presence of the `_rsvp` field implies that this Item in the Feed // represents an event, and it contains additional event-related metadata "_rsvp": { // Points to the v1.json file here "$schema": "https://gitea.jbrumond.me/minimal/docs/raw/branch/master/json-schema/json-feed/extensions/rsvps/v1.json", // Points to this readme doc "about": "https://gitea.jbrumond.me/minimal/docs/raw/branch/master/json-schema/json-feed/extensions/rsvps/readme.md", // The type of RSVP response, one of "invite", "yes", "no", "maybe", or "interested" "rsvp": "yes" } } ] } ```
