The first release of h5check is now available. This tool is a validation tool for verifying that an HDF5 file is encoded according to the HDF5 File Format Specification. The purpose of this tool is to ensure data model integrity and long-term compatibility between evolving versions of the HDF5 library.
The h5check tool can be obtained from the following location:
ftp://ftp.hdfgroup.org/HDF5/special_tools/h5check/
For information on how to use it, please refer to the PDF documentation that comes with it, and which can be accessed from:
ftp://ftp.hdfgroup.org/HDF5/special_tools/h5check/h5check.pdf
The HDF5-OPeNDAP handler version 1.2.2 has been released through the OPeNDAP website at:
http://opendap.org/download/hdf5_handler.html
This is a source-only beta release.
The OPeNDAP software is a software framework that allows simple access to remote data. The HDF5-OPeNDAP handler allows remote HDF5 files and subsets of HDF5 files to be accessed locally.
A second release of the HDF5 .NET APIs is now available. Following are the new features in this release:
This software can be obtained from the HDF5 home page at:
https://support.hdfgroup.org/products/hdf5/index.html
The location of the software is:
https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/HDF5dotNetEnv/
Download and unzip the file: hdf5DotNet18.zip
The release notes can be found with the software and in:
https://gamma.hdfgroup.org/ftp/pub/outgoing/hdf5/HDF5dotNetEnv/ReleaseNotes18.pdf
Please note that this version was built and tested with HDF5 1.8.0. The original prototype, which supports HDF5 1.6 is still accessible from the ftp server location.
This software is not complete and therefore still considered a prototype. If your organization is interested in providing the resources to make this a fully supported and integrated product, just let us know!
THG will be conducting a pilot study on the feasibility of applying user-defined transform operations to data being read from an HDF5 file. This will be done using a dynamic programming language, initially with Python. An RFC outlining the work and seeking feedback is available at:
