Abstract [en]

Collaborative model-driven software engineering fosters efficient cooperation among stakeholders who collaborate on shared models. Yet, the involvement of multiple parties brings forth valid concerns about the confidentiality and integrity of shared information. Unrestricted access to such information, especially when not pertinent to individual responsibilities, poses significant risks, including unauthorized information exposure and potential harm to information integrity. This work proposes a dual-layered solution implemented as an open-source Eclipse plugin that leverages the role-based access control policy to ensure the confidentiality and integrity of model information in collaborative modeling environments. The first layer limits stakeholders' access to the shared model based on their specific roles, while the second layer refines this access by restricting manipulations to individual model elements. By ensuring that stakeholders access only the information pertinent to their roles and are authorized to manipulate such information in accordance with their expertise and responsibilities, this approach ensures the confidentiality and integrity of shared model information. Furthermore, it alleviates information overload for stakeholders by enabling them to focus only on the model information relevant to their specific roles, thereby enhancing the collaborative efforts.

Abstract [en]

Collaborative model-driven software engineering addresses the complexities of developing software systems by prioritizing models as core artifacts and leveraging the collective expertise of diverse stakeholders. To effectively realize this approach, the employed modeling environments must be equipped with features that support and enhance collaboration. These environments should, among other capabilities, provide support for multiple notation types, enabling stakeholders to engage with models using their preferred notation or the notation most appropriate for their tasks. Additionally, they should offer multiple views and perspectives that allow stakeholders to interact with pertinent information only, and implement access control mechanisms to ensure information security. However, the adoption of these features can be challenging, partly because of their resource-intensive and tedious development nature, as well as the necessity for continuous updates to keep up with the evolution of modeling languages. This doctoral thesis proposes a model-driven approach to address this challenge by facilitating the development of blended modeling environments featuring multiple views and ensuring modeled information security. The proposed framework leverages automation to reduce the manual effort and expertise traditionally required for i) the provision of synchronization mechanisms between graphical and textual notations for blended modeling, ii) the provision of synchronization mechanisms between view models and base model in multi-view modeling, and iii) the consistent definition and enforcement of access permissions. This research, therefore, lowers the barriers to adopting these collaborative features by facilitating their development and evolution in face of changes to underlying modeling languages.
