I'm very confused by the docs

The docs shows this way of definining a schema once

type Person {
  name string
}
type Car {
  regnbr string
  owner Person
}
owner uid @reverse .
regnbr string @index(exact) .
name string @index(exact) .

and most other times it would do something like this

type Person {
  name
}
type Car {
  regnbr
  owner
}
owner: uid @reverse .
regnbr: string @index(exact) .
name: string @index(exact) .

Does it make any difference ? Why are there no other references in predicate types inside types apart from here https://dgraph.io/docs/query-language/schema/# (with no explanation about it)

Why do I have to declare a predicate for every single subtype field ? That’s a lot of duplication

I’m having a hard time trying to understand whats the most common or right way to do stuff with dql, the DQL section starts off with a lot of info on functions/filtering/whatever when I still haven’t understood how am I supposed to correctly make a schema

Some more complex graphql to dql schema comparison would be great as well

Yes, the first example doesn’t exist. Can you point out where did you found it?

same here, the docs are very slim. i am very greateful for the amazing Learn courses. But it wouldn’t be bad to update the docs and explain more things and do more examples (good docs are a very important thing, they are really way to slim), and add a comment section (which is a discourse post just inline linked), and add the 123456 (look at picture) lines so that we can better tell which lines at the docs we mean

also it would be cool to have this feature like googles help sites have, so that we can ask/comment-on-posts more directly about issues. that helps a lot for people like amaster and michel to help quicker and save time
