Recently, we have introduced a novel operator for our model transformation language GReAT that  allows the concise specification of complex model (graph) rewriting operations that manipulate entire subgraphs. 

In this paper we show how the new operator can be used to implement non-trivial model manipulations with fewer and simpler rules, while  maintaining efficiency. The examples were motivated by problems encountered in real-life model transformations.</style></abstract></record></records></xml>
