WebHDF5 dataspaces describe the shape of datasets in memory or in HDF5 files. Dataspaces can be empty ( H5S_NULL ), a singleton ( H5S_SCALAR ), or a multi-dimensional, regular grid ( H5S_SIMPLE ). Dataspaces can be re-shaped. Subsets of dataspaces can be "book-marked" or used to restrict I/O operations using selections. http://web.mit.edu/fwtools_v3.1.0/www/H5.intro.html
