Yes, OSmL will be open source under the CPL.

There is very little of it right now, and there is not even an alpha 
version.  This is really on the back burner right now.

However, I don't think OSmL will solve your problem. OSmL does not avoid 
the problem of representing the problem instance in XML format. OSmL is 
designed to produce the problem instance in OSiL format. Hence you still 
have to deal with an instance in OSiL format. OSmL is not a high level 
XML representation -- it generates the instance using XQuery and XPath.

I am curious, why do you think users will shy away from XML more than 
say, MPS or nl formats?  Indeed I would argue that the XML is a lot more 
readable than MPS or nl formats.

Here is a link to a talk I gave on OSmL
