Abstract: Data mapping languages allow users to create knowledge graphs with lower cost and time. Some challenges cannot be solved with state-of-the-art languages and tools, though. Thus, in this paper we use and modify ShExML to deal with some of them. We see how some challenges were already solved, which modifications we had to perform to cover others, and how the rest of them could be covered in future versions. Then, we establish a demonstration on language integrity after changes and a discussion on performed and upcoming changes. These solutions, alongside the discussion and join analysis of other languages and tools solutions, will drive us to effective techniques to solve all proposed challenges.
