Why is DPR freely available?
The National Archives of Australia has licensed DPR under the GNU General Public License version 3 (the GPLv3). Under the terms of the GPL, you are permitted to modify and redistribute the DPR code. You are free to copy and re-use both the source code and the finished DPR product.
The task of digital preservation, regardless of the method used, will always involve working with data in ways likely to cause changes. We are confident that the treatment of digital data by DPR is an effective means of digital preservation, but we don't just ask you to take our word for that. Our source code is available for all to see so that anyone may verify the actions of DPR.
We believe that conducting our software development in an open and public way will better serve to demonstrate the transparency and authenticity of our method of digital preservation. In addition, making our code and documentation freely available has made it easy for others to collaborate with us on further development of the software.
