"WebJul 1, 2024 · XDMF file format is used to describe the data model of the data stored in the HDF5 file. This makes it easy for the end-user to read and understand the hierarchy of data stored in an HDF5 file. In addition to HDF5, XDMF can also store data in XML itself. Thus it is advisable to store heavy data (GB or TB) in XDMF and light data (KB or MB) in XML. " - Fenics ale example
