Domain-Specific Modelling Language for Navigation Applications on S60 Mobile Phones

1. Domain-Specific Modelling Language for Navigation Applications on S60 Mobile Phones Janne Merilinna

2. Outline • Motivation for End-User Driven Development • Solution for End-User Driven Development • DSML for Navigation Applications on S60 • Implementation • DSML • Illustration of the use of the language • Summary • Future work

3. End-User Driven Development- Motivation • Open source? • Enables a possibility to modify application • Enables developing multiple variants • Why not? • Modifying requires to study the existing source code • Don't have time and/or interest • Variants not satisfying enough?

4. Background Domain-Specific Modelling Languages (DSMLs) provide a possibility for very rapid, iterative and incremental software development 5-10 times production gains compared to traditional software development means witnessed in industrial setups. Approach Domain-Specific Modelling Languages Code generators Domain-specific frameworks … and release these as open source and/or open models Objectives Languages that enable rapid development of applications/prototypes New business opportunities e.g. in mass customisation Etc. End-User Driven Development- Solution

14. End-User Driven Development and NavApp • Currently, not that straightforward to use • Notation is what it is…☺ • Solution-space elements should be abstracted -> easier to use • However, it is a lot easier and faster to develop applications vs. manually writing the source code • Still, my mom probably wouldn't be interested in it • (actually, she wouldn't be in any case)

15. What Next? • 1.0 version of the framework and language • Support for multi-person positioning • Multi-player positioning games • Social dimension • Open source? • Open models??
