+#### Resolving
+
+Resolving data is a major part of any GraphQL implementation. We spent quite a lot of time planning how we would solve
+this issue in a way that is easy to build on. The current plan is to use the Front Controller pattern and a front 
+resolver which maps each operation to a corresponding resolver class, very much like a modern router would.
+
+The way this work in practice is that we need to resolve the result for an operation we call the resolver method on
+the front resolver after which it finds the correct resolver, calls it resolver and returns the result. This approach
+also allows us to support middleware for resolver, which is very handy for e.g. transformation or authorization checks.
