Dynamic views on heterogeneous models are an important part of a scalable, agile development process. Current solutions provide, as yet, only limited expressiveness for complex view (type) operations or only partial combination of view type and transformation syntaxes. In this paper, we present our idea of NeoJoin, an easy-to-use view definition language with a combined syntax for view types and complex, incremental transformations. While a prototype is still work-in-progress, we explain the language concepts, we give examples of model queries in our preliminary syntax, and we provide valuable insights into technical challenges, such as the generation of triple graph grammars for the transformations.
