- KonferenzbeitragA flexible operation-based infrastructure for collaborative model-driven engineering(Modellierung 2024, 2024) Herac, Edvin; Marchezan, Luciano; Assunção, Wesley; Haas, Rainer; Egyed, AlexanderCurrent engineering practices to create complex systems rely on highly interdisciplinary teams, potentially globally distributed, working with heterogeneous artifacts. For instance, in a robotics project, collaboration from multiple engineers across different domains such as mechanical, electronic, and software is required. However, achieving proper collaboration to correctly and efficiently develop complex systems is not a trivial activity. The artifacts developed in each domain, usually represented as models, use different structures (e.g., metamodels) and are managed in different tools, but somehow related to each other.
- KonferenzbeitragTransaction validation for XML documents based on XPath(Informatik bewegt: Informatik 2002 - 32. Jahrestagung der Gesellschaft für Informatik e.v. (GI), 2002) Böttcher, Stefan; Türling, AdelhardWhenever mobile devices modify copies of common XML data, then synchronization of multiple user transactions accessing this data is a key problem. However compared to standard XML database systems, transaction synchronization has to solve new problems, i.e. it has to manage lost connections and it furthermore should reduce data exchange over small bandwidth client connections for the purpose of synchronization. In order to avoid locks that are assigned to transactions of "lost" clients, we suggest to use an optimistic approach to synchronization. In order to reduce the data exchange for synchronization, we furthermore suggest to exchange XPath expressions instead of larger XML fragments wherever possible. This allows us not only to treat lost connections more flexible but also to operate efficiently on mobile devices with small bandwidth connections to a server.
