use cases: binary XML for scientifc computing

great to hear this. i think we worked in all those areas -it seems XML
became very popular and now wit convergence on Grid Web Services having
efficient binary XML format that can be used between "optimized" peers
seems to be very important ...
what are use cases for nux: what do you plan to use it for?
are use cases related to XML Binary Characterization
i am a bit disappointed that scientific requirements are completely
omitted form XBC use cases - the closest i could find is
http://www.w3.org/TR/xbc-use-cases/#FPenergy but it skips over whole
issue how to transfer array of doubles without changing endianess ...
I have proposed to the group recently that I create one or more use
cases that cover supercomputing, grid processing, and sensor networks.
observation seems to validate that point. I would be happy to
incorporate anything you could provide. My company builds and
maintains Linux supercomputers and I have present and past experience
with grid-like processing, so I have some resources and contacts.
we worked on SOAP parsing and optimization for scientific computing:
we did lot of work in past related to XML
performance (in Indiana University and Binghamton) and are very
concerned that whatever binary XML will be characterized/standardized
in W3C will be of no much use for scientific computing and grids ...
Could you provide links or details to any of this work?

however we never got enough forward momentum to come up with a proposal
for binary XML but still we are willing to work to get use cases
How do you
think that XML, espeically a binary characterized XML, should related
HDF5 looks to me like a separate problem as it defines its own schema
for its own representation so that is a big task how to make HDF5 to
we are more interested in how to transfer scientific data (mostly
arrays of primitive types or simple structs with primitive types that
can be perfectly well expressed in XML Infoset but are also extremely
inefficient including dreaded IEEE float conversion to string and back)
and make it consistent with XML messaging (such as SOAP).
