 # Terminology
 
 * **Flow context**/**Context** - just a map with all data needed for processing.
-* **Data function** - is everything matching ***Function<Map, Map>***.
+* **Data function** - is everything matching ***Function< Map, Map >***.
 * **Action** - **data function** with a name.
 * **Flow** - sequence of **actions** and a way of their execution and composition. Implements **action**.
 * **Selector** - extension point, that is responsible for based on **context** data selection of concrete extension implementation. Implements **action**.
 * **Extension** - **action** and configuration map, that helps **selector** implementation to match this **extension**. Implements **action**.
 * **Feature** - responsible for registration of **extensions** in **selectors**, stores **extension** to **selector** mapping.
 * **Actor** - performs some **action** upon **context** with provided data and then deduces result of concrete type ***T***. 
-* **Middleware** - named ***BiFunction<Map<String, Object>, Function<Map, Map>, Function<Map, Map>>***,
+* **Middleware** - named ***BiFunction< Map< String, Object >, Function< Map, Map >, Function< Map, Map >>***,
 where second argument is **data-function** to modify, first argument is any kind of meta-data about that **data function**
 and return value is modified **data-function**
 * **Method converter** - converts supplied object into **data function**
