Fop

FOP stands for “Free and Open Source Software”. It is a type of software that is available for anyone to download and use at no cost. It is made by developers who share their code for free, so anyone can use it for whatever purpose they see fit. FOP is usually built to be used for educational and research purposes and often has open source code. Open source means that the source code (the instructions on how the software was made) are available for anyone to view, read, and modify. Because of this, anyone can learn from it, fix it, customize it, and even share it with other people. FOP is becoming more popular because it is often easier to develop and maintain and can provide a great opportunity for collaboration in development.
