-`RagConnect` uses the [relast-preprocessor](https://git-st.inf.tu-dresden.de/jastadd/relast-preprocessor) to parse `.relast` grammar files. This results in an ASTNode of type `Program`.
-It further uses a dedicated parser for `.connect` files containing endpoint-, mapping-, and dependency-definitions. This results in an ASTNode of type `RagConnect`.

 The goal is to generate an aspect file containing setters and getters of tokens referred to by endpoint-definitions
-We use [mustache](https://mustache.github.io/) (currently its [Java version](https://github.com/spullara/mustache.java)) making use of partials resulting in a set of `.mustache` files located in `ragconnect.base/src/main/resources`.
-The generation process uses an intermediate NTA of type `MRagConnect` defined in `MustacheNodes.relast` to separate this generation concern from the content of the DSL

+The `.mustache` files are located in `ragconnect.base/src/main/resources`.
+The generation process uses intermediates NTAs (whose types are defined in `Intermediate.relast`) to ease the definition of two main generation "problems".
+Those problems are differentiation on both kinds of an endpoint (send/receive and type/token/list), and attributes depending on position in n-ary relations.
 
-There are aspect files for `Navigation` (mainly isX/asX attributes), `Analysis` (lookup attributes), `Printing`, `backend/Mappings` (default mappings)
-One of the main aspects is `backend/Generation` containing attributes to construct the `MRagConnect` NTA and all necessary attributes used within the mustache templates
-The other main aspect (which is currently not really used) is `backend/MustacheNodesToYAML.jrag` containing the transformation from a `MRagConnect` subtree to a `Document` subtree defined by `YAML.relast`. This is used to generate a YAML file containing the data used by mustache. It can be used by the default mustache implementation together with the templates.

+One of the main aspects is `Intermediate` containing all attributes consumed by `mustache` and other attributes the former depend on.
