Answer 1

1) Netcdf-4 C library is a layer on top of HDF-5 C library. The API is considered simpler than the HDF5 library, but in the end you have pretty much the same functionality. Netcdf does not support graphs, but HDF5 does. In fact, HDF does not prevent cycles in your graph i think.

2) the HDF group has a Java API on top of HDF-5 C library.

3) Unidata has Netcdf-Java library which is pure Java, but can only read HDF-5.
