-The field generation in this case is handled by [inferFromMapping](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-type.js#L129). The first step is to find the type that is mapped to. In this case, `AuthorYaml`. This is known as the `linkedType`. That type will have a field to link by. In this case `name`. If one is not supplied, it defaults to `id`. This field is known as `linkedField`

If one is not supplied, it defaults to `id`. This field is known as `linkedField`
 
 Now we can create a GraphQL Field declaration whose type is `AuthorYaml` (which we look up in list of other `gqlTypes`). The field resolver will get the value for the node (in this case, the author string), and then search through the react nodes until it finds one whose type is `AuthorYaml` and whose `name` field matches the author string.
 
 #### Foreign Key reference (`___NODE`)
 
-If not a mapping field, it might instead end in `___NODE`, signifying that its value is an ID that is a foreign key reference to another node in redux. Check out the [Source Plugin Tutorial](/tutorial/source-plugin-tutorial/) for how this works from a user point of view. Behind the scenes, the field inference is handled by [inferFromFieldName](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-type.js#L204).

 This is actually quite similar to the mapping case above. We remove the `___NODE` part of the field name. E.g. `author___NODE` would become `author`. Then, we find our `linkedNode`. I.e given the example value for `author` (which would be an ID), we find its actual node in redux. Then, we find its type in processed types by its `internal.type`. Note, that also like in mapping fields, we can define the `linkedField` too. This can be specified via `nodeFieldname___NODE___linkedFieldName`. E.g. for `author___NODE___name`, the linkedField would be `name` instead of `id`.

 #### Plain object or value field
 
-If the field was not handled as a mapping or foreign key reference, then it must be a normal every day field. E.g. a scalar, string, or plain object. These cases are handled by [inferGraphQLType](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-type.js#L38).

These cases are handled by [`inferGraphQLType`](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-type.js#L38).
 
 The core of this step creates a GraphQL Field object, where the type is inferred directly via the result of `typeof`. E.g. `typeof(value) === 'boolean'` would result in type `GraphQLBoolean`. Since these are simple values, resolvers are not defined (graphql-js takes care of that for us).
 
-If however, the value is an object or array, we recurse, using [inferObjectStructureFromNodes](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-type.js#L317) to create the GraphQL fields.

 In addition, Gatsby creates custom GraphQL types for `File` ([types/type-file.js](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/types/type-file.js)) and `Date` ([types/type-date.js](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/types/type-file.js)). If the value of our field is a string that looks like a filename or a date (handled by [should-infer](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-type.js#L52) functions), then we return the appropriate custom type.

-This step is handled by [inferInputObjectStrctureFromNodes](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/schema/infer-graphql-input-fields.js#L235). First, we generate an example Value (see [gqlTypes](/docs/schema-gql-type#gqltype-creation)). For each field on the example value (e.g. `author`), we create a [GraphQLInputObjectType](https://graphql.org/graphql-js/type/#graphqlinputobjecttype) with an appropriate name. The fields for Input Objects are predicates that depend on the value's `typeof` result. E.g. for a String, we need to be able to query by `eq`, `regex` etc. If the value is an object itself, then we recurse, building its fields as above.
