I was unaware of this source of data - I wonder how many data
repositories exist like the one that Ton describes? I maintain a couple
of public data sources but had not really thought of them in these
terms. These are:

ftp.c3d.org/data - approximately 40Mb of example C3D files designed
to enable users and software developers to check that their applications
read C3D files correctly. Most of these files contain biomechanical
data of human gait.

ftp.emgsrus.com/sample - about 25Mb of multichannel EMG recording in
C3D and ASCII formats.

Both of these collections were originally made available for all of
the reasons that Ton lists above. It's worth noting that in both cases
we store data using the C3D file format because it's the nearest thing
to a (non-ASCII) universal storage format for biomechanics data.

I wonder how many other data collections exist on the Internet like
this that are "public" but not publicized at all? Search engines such
as Google and Alta Vista are very good at finding web pages but are
quite poor are locating data repositories unless they are clearly
flagged as such ... and I'll readily admit that our data has never been
set up to be easily indexed by any search engines.

While I hesitate to suggest that Ton and the other folks at BIOMCH-L
add more work to their plate - perhaps we need a web page on the
www.isbweb.org site that just lists public data sources? There may be
more out there than we realize.
