Product configuration of a software product line using a Domain Specific Language

A Software Product Line (SPL) reuses software assets to implement products that share a significant set of their features. When developer needs generate new product, the selection features determines which components and source code are assembled together as product. In recent years, Database Laboratory has been working with SPL tech- nologies in field Geographic Information Systems (GIS). Our creates from specification allows, addition defining data model application, customize specific elements application such maps associated layers. However, during its use real projects we detected this customization was insuf- ficient: since selected included for whole if need feature only element, apply it all same type. paper propose solution that, using Domain Specific Language, allows associate generated order achieve greater GIS improve quality. This way, is possible select (e.g., clustering) element map-viewer), thus limiting functionalities those parts where they really necessary.
