+# TypeSchema
+
+## Tests
+
+This directory contains test TypeSchema specifications using different features of the specification.
+If you want to build a generator or parser it is recommended to test your library against these tests.
+Your generator is level 5 compliant in case it can work with all levels of the specification.
+
+## Level 1
+
+Tests whether it is possible to work with a simple structures. It tests also that it is possible to
+reference a different struct. This is the most basic feature which every processor should support.
+
+## Level 2
+
+Tests whether it is possible to use array and map data types. Inline means that the native array/map
+data types are used. Array and map definition types result in a custom array or map implementation.
+
+## Level 3
+
+Tests whether it is possible to extend a struct. If supported a generator should produce two classes
+with an actual extend.
+
+## Level 4
+
+Tests whether it is possible to use generics. Generic placeholder at a struct can be replaced on usage
+with actual types. A generator should produce actual generics if the language supports this.
+
+## Level 5
+
+Tests whether it is possible to use discriminated union. Through a discriminated union it is possible
+to use different schemas depending on a discriminated type value.
