RFCs (Requests For Comments) are documents posted by developers, requesting feedback regarding new features or changes being proposed for the HDF software.
Following are three new RFCs for HDF5, which may be of interest to users (Please note that the location of the RFCs listed below is different than the location of the HDF Group home page.):
Provides an indexing scheme to enable scientists to efficiently extract information from large, complex datasets.
Uses journaling to provide periodic rollback points, so as to minimize file corruption in HDF5.
Provides performance improvements for unlimited 1-dimensional chunked datasets, by use of Skip Lists.
h5import is an HDF5 tool that converts floating point or integer data stored in ASCII or binary files into the HDF5 format. Currently h5import only processes numeric data. The HDF Group plans to add support for importing text data into HDF5 using h5import.
We are now soliciting use cases that will guide the design of the text import feature in h5import. Please consider text you might want to import and how you would want to access that text once it is in the HDF5 file, and send your use cases to pvn@hdfgroup.org before September 17, 2007.
Thank you for your help as we strive to improve our tools.
