Helloo, I'm having a hard time understanding the use of each of the user-schema's attribute keys. Like in the section

"<http://ory.sh/kratos|ory.sh/kratos>": {
        "credentials": {
          "password": {
            "identifier": true
          }
        }
      }

how is the "ory.sh/kratos" section is used, what it means and same for "credentials" section, what we can put here other than password, also what does the boolean of "identifier" means, or such questions. Do you know what I can look at to understand everything in this ? (There is a lot of documentation by examples, but can't find much for each of those keys, maybe i'm missing something)

Hi! The whole identity schema is based on JSON schema, a language to define the schema of JSON documents. “ory.sh/kratos” is an ory specific extension. Read more here: https://www.ory.sh/docs/kratos/manage-identities/identity-schema#identity-schema-vocabulary-extensions
