Semantic Differencing of Domain-Specific Models

点击翻译按钮获取中文摘要

Project Objectives: To investigate approaches to compare domain-specific models and present theidentified differences using effective semantics-aware visualisations. The project will address three keyresearch questions:1. To what extent can the graphical syntax of a domain-specific language be reused to visualisedifferences in models that conform to it in a meaningful way?2. Can bespoke transformations produce more effective semantics-aware visualisations thangeneric abstract-syntax driven differencing algorithms (e.g. such as those implemented in toolslike EMFCompare and EMF Diff/Merge)?3. If so, can commonalities be identified in such bespoke transformations, which could be pulled upto a higher level of abstraction and simplify their development?
