Adding Mobilizon (events) as a source: multiple potential fields for the same attribute ?
First of all, thank you for this extension !
We met a few days back and as I told you I'd like to add Mobilizon as a kind of source, which should hopefully convince more people to use Mobilizon. Discoverability is, to me, the biggest problem of the decentralized web and I feel like Meta-press.es can be hacked to tackle this problem.
Mobilizon is using GraphQL for its API. This means POSTing a body with a specific structure, and the reply is a JSON.
Here's the blurb in the request:
```
{"query":"query SearchEventsAndGroups($location: String, $radius: Float, $tags: String, $term: String, $type: EventType, $category: String, $beginsOn: DateTime, $endsOn: DateTime, $eventPage: Int, $limit: Int) {\n searchEvents(location: $location, radius: $radius, tags: $tags, term: $term, type: $type, category: $category, beginsOn: $beginsOn, endsOn: $endsOn, page: $eventPage, limit: $limit) {\n total\n elements {\n title\n url\n beginsOn\n attributedTo {\n name\n }\n organizerActor {\n name\n }\n }\n }\n}\n","variables":{"term":"concert"},"operationName":"SearchEventsAndGroups"}
```
Basically, a JSON object with a `query` field and `variables`. The query looks like this when formatted:
```
query SearchEventsAndGroups($location: String, $radius: Float, $tags: String, $term: String, $type: EventType, $category: String, $beginsOn: DateTime, $endsOn: DateTime, $eventPage: Int, $limit: Int) {
searchEvents(location: $location, radius: $radius, tags: $tags, term: $term, type: $type, category: $category, beginsOn: $beginsOn, endsOn: $endsOn, page: $eventPage, limit: $limit) {
total
elements {
title
url
beginsOn
attributedTo {
name
}
organizerActor {
name
}
}
}
}
```
(Note: this is not the query used by the actual frontend, which is waaaaaay more complicated. It includes stuff like location, events options etc that might not be relevant for Meta-Press.es)
The reply is a standard JSON:

To play with the API, here's a very helpful link targeting the main instance directly: https://mobilizon.fr/graphiql
So, it seems to be pretty straightforward, but there's an issue: as you can see we need to include both `organizerActor` and `attributedTo` because sometimes one is null and we must use the other. Hence the question: is it possible to indicate two fields and take the first one that is not null ?
