Model-driven tools use model queries for many purposes, including validation of well-formedness rules, speci-cation of derived features, and directing rule-based model transformation. Query languages such as graph patterns may facilitate capturing complex structural relationships between model elements. Specifying such queries, however, may prove di-cult for engineers familiar with the concrete syntax only, not with the underlying abstract representation of the modeling language. The current paper presents an extension to the EMF-IncQuery model query tool that lets users point out, using familiar concrete syntax, an example of what the query results should look like, and automatically derive a graph query that -nds other similar results. by example model query graph pattern EMF-IncQuery.
