Jean Zay: The HDF5 library


HDF signifies Hierarchical Data Format. This format was developed by the National Center for Supercomputing Applications (NCSA) and is now supported by The HDF Group. It facilitates the handling of files containing very large quantities of data through prioritisation in tree hierarchies.
