Hdf5JavaLib

Hdf5JavaLib is a pure Java library for reading HDF5 files, currently in beta. It supports reading datasets in the root group, such as compound datasets, scalars, vectors, and multi-dimensional data tested up to 4D, from files generated by the C++ HDF5 library. This library is ideal for developers experimenting with HDF5 file reading in Java without external dependencies.

Getting Started

1. Clone the Repository:

   git clone https://github.com/karlnicholas/Hdf5JavaLib.git

2. Build with Maven:

   cd Hdf5JavaLib
   mvn install

3. Requirements:
   • Java 17+.
   • No external HDF5 libraries needed.

Read Capabilities

The library reads datasets in the root group, including:

• Compound datasets (e.g., structured data with integers, strings).
• Scalar, vector, and multi-dimensional datasets (tested up to 4D).
• Various datatypes (fixed-point, floating-point, strings, etc.).

For detailed usage and examples, see the Read Capabilities Documentation.

Limitations

• Beta Status: Limited to reading datasets in the root group.
• No Subgroups: Groups beyond the root group are not supported.
• No Compression or Chunking: Cannot read compressed or chunked datasets.
• Partial Metadata: Supports SNODs but not attributes or advanced structures.
