Second Workshop on Software Development at Neutron Scattering Sources
       NIST, Gaithersburg, Maryland, USA (Sept. 1995)

One of the recommendations of the first Workshop on Software Development at
Neutron Scattering Sources (SoftNeSS'94), held last October at Argonne
National Laboratory, was to establish a standard format for the exchange
of neutron data among neutron scattering facilities and the user
community.  The reports containing this and other recommendations are
available as an ASCII postscript file from or by
contacting Ray Osborn (ROsborn at

The meeting recommended that data be stored using HDF, a public
domain network-transparent database format developed by the National
Center for Supercomputing Applications at the University of Illinois -
Urbana-Champaign.  A draft proposal outlining the basic structure of
HDF files has been produced by Przemek Klosowski (NIST), Mark Konnecke
(ISIS) and Jon Tischler (ORNL), and is available as the postscript
file "" in the same subdirectory as the SoftNeSS report.

We propose to hold a second workshop, this time at the National
Institute of Standards and Technology (NIST) near Washington DC,
in September this year, in order to produce a comprehensive
proposal and settle a number of related issues.  Items on the agenda will

---- Discussion of the proposed file structure
---- Application to specific neutron instrumentation and experiments
       (e.g. triple-axis spectrometers, small-angle scattering instruments,
       time-of-flight spectrometers, real-time scans etc.)
---- Naming conventions for neutron scattering parameters
---- Provision of utilities and subroutine libraries for writing and
       reading the HDF files.

If you are interested in contributing to the process of defining the data
format standard, please let us know by sending an E-mail message either
to John Copley (John.Copley at or to Ray Osborn (ROsborn at
We ask that participants cover their own travel and accommodation costs.
The dates of the workshop will be finalized following the response to
this first notice, so please tell us dates in September that you will be
