I consider a DSL something that has its own lexer/parser, like SQL. Since Rama's dataflow API is just Java (there's also a Clojure API, btw), that means you never leave the realm of a general purpose programming language. So you can do things higher-order things like generate dataflow code dynamically, factor reusable code into normal Java functions, and so on. And all these are done without the complexity and risks of doing so by generating strings for a separate DSL, like you get when generating SQL (e.g. injection attacks).
