I think this is all fine. The important bit is: http://www.jmodelica.org/page/24 which says that JModelica is available under GPLv3, which is OK for Sage. Almost any software is going to be the property of somebody; that's fine. > from http://www.jmodelica.org/page/14 > """ > JModelica.org is an open source project maintained and owned by > Modelon AB.

It doesn't restrict your freedom to fork the project, which is the important bit. (The Free Software Foundation also requires copyright assignment to submit code to any of their projects, like gcc or emacs.)
