Get your Bearings with HDF Compass

John Readey, The HDF Group

We’ve recently announced a new viewer application for HDF5 files: HDF Compass. In this blog post we’ll explore the motivations for providing this tool, review its features, and speculate a bit about future direction for Compass.

HDF Compass is a desktop viewer application for HDF5 and other file formats. A free and open source software product, it runs on Mac OS X, Windows, and Linux.

Letter to the HDF User Community

Lindsay Powers – The HDF Group

The HDF Group provides free, open-source software that is widely used in government, academia and industry. The goal of The HDF Group is to ensure the sustainable development of HDF (Hierarchical Data Format) technologies and the ongoing accessibility of HDF-stored data because users and organizations have mission-critical systems and archives relying on these technologies. These users and organizations are a critical element of the HDF community and an important source of new and innovative uses of, and sustainability for, the HDF platforms, libraries and tools.

We want to create a sustainability model for the open access platforms and libraries that can serve these diverse communities in the future use and preservation of their data. As a step towards engaging this community, we are seeking partners for a National Science Foundation Research Coordination Network (RCN).

The National Science Foundation supports RCNs in order to foster collaboration and communication among scientists and technologists in the areas of research coordination, education and training, collaborative technologies, and standards development. Our vision of this RCN is to develop a core community of experienced and dedicated HDF users to:

  1. Foster education and training of new and existing users through development of teaching modules, workshops and other mechanisms for sharing knowledge and experience,
  2. Provide a forum for sharing tools and techniques related to HDF technologies,
  3. Convene diverse users to foster interdisciplinary collaboration, and
  4. Formalize a community of committed HDF users invested in the sustainability of HDF products.

America Runs on Excel and HDF5*

* With Python’s Help

Gerd Heber, The HDF Group

Before the recent release of our PyHexad Excel add-in for HDF5 [1], the title might have sounded like the slogan of a global coffee and baked goods chain. That was then. Today, it is an expression of hope for the spreadsheet users who run this country and who either felt neglected by the HDF5 community or who might suffer from a medical condition known as data-bulging workbook stress disorder. In this article, I would like to give you a quick overview of the novel PyHexad therapy and invite you to get involved (after consulting with your doctor).

To access the data in HDF5 files from Excel is a frontrunner among the all-time TOP 10 most frequently asked for features. A spreadsheet tool might be a convenient window into, and user interface for, certain data stored in HDF5 files. Such a tool could help overcome Excel storage and performance limitations, and allow data to be freely “shuttled” between worksheets and HDF5 data containers. PyHexad ([4],[5],[6],[7]) is an attempt to further explore this concept.   Continue reading
