What are licensing restrictions of open source software?
There is a range of open source licenses, and the Open Source Initiative is a good source for information on this topic. Two common open source licenses include: Apache Software License – allows free use and distribution of the software and documentation. This is preferred by ISVs that incorporate open source software in their commercially available products. GNU general Public license (GPL) / GNU Lesser general Public license (LGPL) – allows free use of the software and documentation, but users cannot redistribute it in their own products.
