Registered Third-Party Filters (Compression)
Members of the HDF5 users community can register Third-Party compression filters for use with HDF5.
To register a filter please contact The HDF Helpdesk with the following information:
- Contact information for the developer requesting a new identifier
- Short description of the new filter
- Links to any relevant information including licensing information
Here is the current policy regarding filter identifier assignment:
The filter identifier is designed to be a unique identifier for the filter. Values from zero through 32,767 are reserved for filters supported by The HDF Group in the HDF5 library and for filters requested and supported by the 3rd party.
Values from 32768 to 65535 are reserved for non-distributed uses (e.g., internal company usage) or for application usage when testing a feature. The HDF Group does not track or document the usage of filters with identifiers from this range.
Please contact the maintainer of a filter for help with the filter/compression support in HDF5.
