HDF5 File Organization

An HDF5 file is a container for storing a variety of scientific data is composed of two primary types of objects: groups and datasets.

Any HDF5 group or dataset may have an associated attribute list. An HDF5 attribute is a user-defined HDF5 structure that provides extra information about an HDF5 object.

Working with groups and datasets is similar in many ways to working with directories and files in UNIX. As with UNIX directories and files, an HDF5 object in an HDF5 file is often referred to by its full path name (also called an absolute path name).
