HI Craig,
	Thanks for your reply.
	Our goal is to have an XML based materials format we can use to

exchange data between the various applications that the ESI group  
develops and with services such as MatWeb.  I am approaching MatML  
from the point of view of finite-element based simulation  ( think   
Nastran), rather than material science.
	I was hoping that MatML would have been widely adopted and that
a  
standard glossary would have evolved, but that does not seem to be  
the case.  I believe ANSYS has a flavor of MatML to exchange data ,  
but the ANSYS XSD is not published, so adopting their format would be  
a matter of reverse engineering. The generality=complexity and lack  
of a standardized glossary of MatML is definitely a barrier to adoption.

	I would be happy to discuss this with a Committee member.

Andrew
