EMF Views: A View Mechanism for Integrating Heterogeneous Models - ER 2015 @ Stockholm, Sweden
2 likes1,513 views
The document discusses the 'EMF Views' mechanism for integrating heterogeneous models, emphasizing the need for a model view approach that maintains genericity, expressivity, non-intrusiveness, interoperability, modifiability, synchronization, and scalability. It introduces a viewpoint definition language (VPDL) and outlines a conceptual framework for building and managing views at both design and runtime. The authors present future work directions, including enhancements to VPDL and addressing the view update problem.
