Hierarchical Data Format
<file format, data> (HDF) A library and multi-object file format for the
transfer of graphical and numerical data between computeres. The freely
available HDF distribution consists of the library, command line utilities, test
suite source, Java interface, and the Java-based HDF Viewer (JHV).
HDF supports several different data models, including multidimensional arrays,
raster images, and tables. Each defines a specific aggregate data type and
provides an API for reading, writing, and organising the data and metadata. New
data models can be added by the HDF developers or users.
HDF is self-describing, allowing an application to interpret the structure and
contents of a file without any outside information.
One HDF file can hold a mixture of related objects which can be accessed as a
group or as individual objects. Users can create their own grouping structures
called "vgroups".
HDF files can be shared across most common platforms, including many
workstations and high performance computers. An HDF file created on one computer
can be read on a different system without modification.
