This extension adds a read and write operator for HDF5 files. The reader transforms the data sets from an HDF5 file to RapidMiner example sets, making use of the random access possibilites of the HDF format. Not all formats can be mapped to RapidMiner, thus those are not supported and will not be visible in RapidMiner (although they still exist in the file). The write operator transforms RapidMiner example sets to HDF5 compound data sets and writes them to a specified file.

Formats not supported are:

• Compound (tables in tables)
• No Class
• Opaque
• Reference
• Bitfield

HDF is a widely used big data format developed by The HDF Group.
