Tired of manually maintaining collections of similar-but-yet-not-the-same meta-models? Frustrated for having to develop yet-another-transformation-variant for these meta-models? Then you are in the right place: Merlin is a tool to engineer and analyse meta-model product lines, and their associated transformation product lines.
Merlin extends FeatureIDE to create feature models and build meta-model products. Meta-model product lines can be analysed syntactically for well-formedness, including the associated OCL constraints. It is also possible to analyse instance level properties (i.e., properties of the instance models of the meta-models of the product line), using constraint solving techniques. Merlin uses the USE validator for this purpose.
On top of meta-model product lines, Merlin also supports the creation and analysis of transformation product lines using the Epsilon model management languages. While we provide built-in support for OCL and Epsilon, Merlin is open to other transformation languages.
