Open CASCADE license

Hi,

Maybe this is a faq, but I wasn't able to find this info in this forum, nor at usenet, nor at www.opencascade.org/com. If this question has already been answered, please point me to the right place.

How does the Open CASCADE license (MDPL) compare with the licenses at http://www.opensource.org/licenses/ such as the GPL, the LGPL, BSD, MIT, etc...?

In particular, I'm specially interested in how the license affects applications built using Open CASCADE. The license cares a lot about the development of Open CASCADE itself, and says very little about applications which use the software.

There's a paragraph about derivative programs, but it's written just as a clarification and I feel it's a bit ambiguous. For example, it doesn't specify whether an application that uses the software at runtime is a derivative program or not.

Any help greatly appreciated,

César Blecua.
