Can I use MapGuide Open Source to create my own proprietary applications?
Yes. Unlike the GNU General Public License (GPL), the LGPL does not force you to open source your application just because you integrate it with code from MapGuide Open Source. If your application merely links dynamically to MapGuide Open Source software at runtime, and does not include a changed version of MapGuide Open Source, you have created what the license refers to as a “work that uses the library” and you need only comply with the requirements in Section 6 of the LGPL. Broadly speaking, this section requires you simply to give notice that your application contains LGPL code and pass along a copy of the license and a copyright notice for MapGuide Open Source.
