Open Source software is distributed under a variety of licenses each of which usually permits licensee to distribute and modify the software, provided that the licensee complies with a specified set of terms and conditions. A question that can therefore arise, is a licensee legally permitted to create modifications which combine elements of two (or more) different existing works into a single work, and distribute the result?
The answer is that these types of combinations are generally only legally permitted if the licensee can comply with all the pertinent terms and conditions of all the licenses.
