# GraphQL endpoint generation for Weaviate
-The point of external access is in graphql_schema.go (CreateSchema()). The schema is assembled in its entirety in assembleFullSchema() in build_schema.go
+The point of external access is in `graphql_schema.go` (`CreateSchema()`). The schema is assembled in its entirety in `assembleFullSchema()` in `build_schema.go`.
## The schema
-The schema is based on GraphQLObjects. These GraphQLObjects have a property that contains a GraphQL.Fields{} object, which is a hashmap. This map contains one or more GraphQL.Field objects. These Field objects have Scalar values or other objects as Type.
+The schema is based on `GraphQLObjects`. These `GraphQLObjects` have a property that contains a `GraphQL.Fields{}` object, which is a hashmap. This map contains one or more `GraphQL.Field` objects. These `Field` objects have `Scalar` values or other `GraphQLObjects` as value.
## The code
-The code is divided in functions that return a single GraphQLObject and its properties (including the Fields property, which can contain Field objects with GraphQLObject types). The aim of this is to make the code easier to read. The code for schema generation is divided in a statically generated part, a dynamically generated part and filter functionality.

-Both filters and Things/Actions can contain cyclical relationships; these cases are solved by using thunks.
