| Abstract [eng] |
SysML v2 introduces new challenges in model differencing because of its textual notation, reduced dependence on tool-specific exchange formats, and explicit structural relations between model elements. Existing differencing approaches designed mainly for UML, XMI-based models, or identifier-dependent versioning scenarios are not fully suitable for SysML v2. This paper analyzes the characteristics of SysML v2 relevant to model comparison and reviews existing differencing approaches and tools in order to identify the main requirements for SysML v2 model differencing. Based on this analysis, the main concepts of a graph-based SysML v2 differencing solution are proposed. The proposed process includes transformation of models into abstract syntax trees, matching of model elements, generation of a delta script, and presentation of detected changes in textual and graphical form. In addition, optional summarization of differencing results using a large language model is considered to improve the readability of comparison output. An illustrative example demonstrates how the proposed approach can organize the results according to SysML v2 specific concepts. |
