Machines currently sup- - ported include the Cray, Convex, HP, Vax, Sun, IBM - RS/6000, Silicon Graphics, Macintosh, and IBM PC comput- - ers. HDF allows self-definitions of data content and easy - extensibility for future enhancements or compatibility - with other standard formats. HDF includes Fortran and C - calling interfaces,and utilities to prepare raw image of - data files or for use with other NCSA software. The HDF - library contains interfaces for storing and retrieving - compressed or uncompressed 8-bit and 24-bit raster images - with palettes, n-Dimensional scientific datasets and - binary tables. An interface is also included that allows - arbitray grouping of other HDF objects. +HDF technologies at present include two data management formats (HDF4 and HDF5) +and libraries, a modular data browser/editor, associated tools and utilities, +and a conversion library. Both HDF4 and HDF5 were designed to be a general +scientific format, adaptable to virtually any scientific or engineering +application, and also have been used successfully in non-technical areas. The +Open Source format is a key technological foundation for HDF core technologies. +It allows users to collaborate with The HDF Group regarding functionality +requirements and permits users' experience and knowledge to be incorporated into +the HDF product when appropriate. It also permits users and organizations +without adequate technology resources to use a sophisticated and robust data +management tool for no charge. WWW: http://www.hdfgroup.org/products/hdf4/ |
