Metaphorically speaking, this blog post is about a frog trying to climb out of a well, a damp and unsightly corner of the HDF5 ecosystem called HDF5.NET. People who know more about its genesis tell us that it was never intended as what it became to be perceived as, an “aspirational” .NET interface for HDF5 that would one day be complete and fully supported. Be that as it may, it’s important to ask, “What can we do today to better serve the needs of the .NET community?” We believe, as the title suggests, we need to take a step back to move forward.

The first week of January brought leaders of the Earth Science informatics community together in Washington DC for the winter meeting of the Federation of Earth Science Information Partners (ESIP Federation). This year NOAA’s Environmental Data Management Workshop was co-located with ESIP for five exciting days of data management ideas and discussions. The HDF Group was well represented at both of these meetings with presentations on metadata and data containers.
The ESIP Federation comes together twice each year to discuss topics around changing technology, data, information and knowledge in support of society. ESIP meetings are interdisciplinary and inclusive. Among the attendees are Earth science data and information technology practitioners; researchers representing a variety of scientific domains that include land, atmosphere, ocean, solid earth, ecology, data and social sciences; science educators; and anyone working in science and technology-related fields who is interested in advancing Earth science information best practices in an open and transparent fashion.

The Single Writer/Multiple Reader and Virtual Data Set features, below, are both contained in this alpha release as are scalable chunk indexing and persistent free file space tracking. More features, such as enhancements to parallel HDF5 and support for compressing contiguous datasets will be added in upcoming alpha releases.
Here are the highlights: Continue reading
