I like the sound of this (the majority of the data is the same
length). I haven't noticed a way yet of adding columns to a matrix, is
this straightforward? If it is, I can store the column names and
numbers in a different dataset and the actual values as a large 2d
matrix.
Pretty much, check for |H5S_UNLIMITED| in the dataspace description:
http://www.hdfgroup.org/HDF5/doc/RM/RM_H5S.html
The dataset needs to be chunked, but is extensible beyond its initial
size if its dimension is set to be unlimited rather than a constant
value at creation.
