What Else in HDF5?

What else is there in HDF5?

Plenty. I have skipped the whole issue of accessing HDF5 objects by references (or addresses, or locations). This is useful if you want to create a list of certain objects, store the list on a special dataset, then use it to iterate, for example, over the objects. The objects collected this way don't have to live in the same group, otherwise you could simply use H5Giterate to pick them up. Once you have an object you can obtain its address, within the file, by calling function  H5Rcreate. You can also create lists of references to specific regions within the datasets, also by calling the same function H5Rcreate.

I have only showed you three HDF5 tools, h5dump, h5ls and h5cc, but there are more:

h5diff

  identifies and locates differences between two HDF5 files

h5repart

  lets you re-partition an HDF5 file and create a file family out of it

h5import

  lets you import data into an existing or a new HDF5 file

gif2h5

  lets you convert a GIF file to an HDF5 file

h52gif

  lets you extract images from an HDF5 file onto GIF files

h5perf

  lets you measure performance of HDF5 programs

h5fc

  lets you compile Fortran90 programs that call HDF5 functions

H5c++

  lets you compile C++ programs that call HDF5 functions

h4toh5

  lets you convert an HDF4 file to an HDF5 file

h5toh4

  lets you convert an HDF5 file to an HDF4 file

JHI5

  is the Java  package that wraps around HDF5

H5View

  is a Java-based tool for browsing and editing HDF5 files

H5gen

  is a Java utility that reads an XML description of an HDF5 file and generates the corresponding HDF5 file

VisAD

  is a Java toolkit for constructing interactive and collaborative visualization and analysis of numerical data
