The UCAR Research Applications Laboratory (RAL) has released version 1.4 of Nujan, a pure Java library for writing HDF5 and NetCDF4 files. Nujan is 100% open source and is released under the MIT license. Nujan is intended to be useful in situations where portability and a simplified development process are more important than access to the complete HDF5 feature set.
Nujan creates files compatible with:
- HDF5 1.8.5 and later
- NetCDF 4.1.1 and later
The primary differences between the Nujan writer and other NetCDF or HDF5 writers are:
- Nujan is pure Java. It does not depend on any non-Java code or use the JNI (Java Native Interface).
- The Nujan writer only writes new files. It does not update existing files.
Nujan supports most of the commonly used features of NetCDF4 and HDF5, but does not implement all features. For details and to download Nujan:
