Reverse References

In both FlureeQL and GraphQL, you can follow a reference both forwards and backwards. For example, in previous lessons, we saw that chat/person is a ref type. In order to see information about a person when we start from the chat collection, we would issue a query like the following:

{
  graph {
    chat {
      message
      person {
        handle
        fullName
      }
    }
  }
}

We can also see information about chats when we start from the person collection. In order to do this, we need to include a predicate chat_Via_person, and within the curly braces following chat_Via_person, we specify any chat predicates we want displayed:

{
  graph {
    person {
      chat_Via_person {
        _id
        instant
        message
      }
    }
  }
}

Write a Query!

Write a GraphQL query selecting `person/handle` and `person/fullName` starting from the `artist` collection.

Use the above query for reference.
