1. Cross-Platform Blended Modelling with JetBrains MPS and Eclipse Modeling Framework

Modelling tools traditionally focus on one specific editing notation (such as text, diagrams, tables or forms), providing additional visualisation-only notations. For software-intensive systems with heterogeneous components and entailing different domain-specific aspects and different stakeholders, one editing notation is too little and voids many modelling benefits. Seamless blended modelling, which allows stakeholders to freely choose and switch between graphical and textual notations, can greatly contribute to increase productivity as well as decrease costs and time to market. In this paper we describe our work in bridging two powerful (meta) modelling platforms: Eclipse Modeling Framework, for the definition of tree-based and graphical DSMLs and models conforming to them, and JetBrains MPS, for the description of textual DSMLs and the projectional manipulation of textual models via multiple views. The possibility to visualise and edit the same information in these two platforms, otherwise disjoint, can greatly boost communication between stakeholders, who can freely select their preferred notation or switch from one to the other at any time.
