HDF (Hierarchical Data Format) is a multi-object file format, developed at NCSA, that facilitates the transfer of various types of data between machines and operating systems
The hierarchical data format supports the storage of many different data types, including images and tables Tools for using HDFs are available for most higher-end machines, including most UNIX systems, Macs with a PowerPC processor, and Windows NT & Windows '95 systems that possess at least a Pentium processor There is also a Java interface for handling HDFs
A flexible, standard, public-domain file format designed for sharing graphical and floating point data among different programs and machines
NCSA's Hierarchical Data Format Unlike FITS, this data format is defined by a particular implementation and subroutine library interface The format is in wide use in the physical sciences, and NCSA provides a number of sophisticated data browsing tools
Hierarchical Data Format - a network-transparent and self-describing data format developed at NCSA
