Does RAGS allow alternative levels of representation, e.g. information structure, topic/comment etc?
RAGS only specifies certain “core” types of representation which we think most NLG systems will want to use. Users of RAGS can use extra levels of representation and don’t need to use all of our levels. As long as you use some RAGS representations, you will be able to exchange datasets with other people and you will be able to use modules other people have written which use those representations. There is no reason why other people should not propose other levels of representation to be incorporated within the general RAGS structure.
