Provides for importing data to and exporting data from VisAD. The VisAD data backend subsystem is implemented as a heirarchy of data forms. A data form is the form in which the data is contained. I could be, for example, a netCDF or HDF-EOS dataset, or a FITS file. It could also be local or remote. The term form is used rather than format to encompase both data access methodologies (e.g. the netCDF API) and the more traditional data file formats.
