From the Open Source Definition: > 9. License Must Not Restrict Other Software > The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.

Does the MondoDB license run afoul of that? My limited understanding is that the problematic part of the new MondoDB license is a clause that says that if you offer MongoDB as a service, you have to make source for it and all software involved in that offering (such as control panels, management interfaces, and so on) available for download. That doesn't sound like it would be incompatible with section 9 of the OSD, as section 9 covers software whose distribution imposes restrictions on other software. MondoDB's license is imposing a condition based on usage, not distribution, of MongoDB. If MongoDB's license does not satisfy the OSD, I think it is probably section 6 that it conflicts with: > 6. No Discrimination Against Fields of Endeavor > The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

  "Other software" also includes "control panels, management interfaces, and so on".
