Hierarchical Data Format (HDF)

The Hierarchical Data Format (HDF) is a data model, file format and I/O library designed for storing, exchanging, managing and archiving complex data including scientific, engineering, and remote sensing data. The latest version of HDF, HDF5 allows users to read only the data that they need, not the whole file. Data producers can put images, tables, multidimensional arrays, etc into the same file.
