This paper introduces the graph-based transformation language GReTL. GReTL is an operational transformation language whose operations are either specified in plain Java using the GReTL API or in a simple domain-specific language. GReTL follows the conception of incrementally constructing the target metamodel together with the target graph. When creating a new metamodel element, a set-based semantic expression is specified that describes the set of instances that have to be created in the target graph. This expression is described by a query on the source graph. After a description of the foundations of GReTL, its most important elements are introduced along with a simple example. © 2011 Springer-Verlag.
