LPFML has been extended to an XML-based format, designated OSiL, for LP/MIP and
other kinds of optimization problems (such as nonlinear optimization).  There's
an updated description of it at
www.optimization-online.org/DB_FILE/2006/03/1353.pdf.

There's a format similar to OSiL -- designated OSrL -- for communicating
optimization results from solvers.  A broader framework, called Optimization
Services, defines a number of other formats relating to optimization.  A start
on a website for it can be seen at www.optimizationservices.org, and it will be
distributed as a project from COIN-OR (www.coin-or.org) within a few months.
