The Reciprocal Public License (RPL) is a copyleft software license released in 2001.[1] Version 1.5 of the license was published on July 15, 2007,[1] and was approved by the Open Source Initiative as an open-source license.[2]

Description

{{refimprove section|date=November 2016}}

The RPL was authored in 2001[3]{{psi|date=November 2016}} by Scott Shattuck, a software architect for Technical Pursuit Inc. for use with that company's TIBET product line.

The RPL was inspired by the GNU General Public License (GPL) and authored to explicitly remove what the RPL's authors have referred to as the GPL's "privacy loophole". The GPL privacy loopholes allows recipients of GPL'd code to:

  1. make changes to source code which are never released to the open source community (by virtue of not deploying "to a third party"), and
  2. derive financial or other business benefit from that action, violating what some might consider a simple concept of "fairness".

Because of its "viral" nature, the RPL is often found in dual-licensing models in which it is paired with more traditional closed-source licenses. This strategy allows software companies who use this model to present customers with a "pay with cash or pay with code" option, ensuring either the growth of the software directly through code contributions or indirectly through cash which can be used to fund further development.

Reception

The RPL was written to conform to the requirements of the Open Source Initiative to ensure that it met the goals for an Open Source license and is an approved open-source license. However, because of its requirements for reciprocation without exceptions, it is considered to be non-free by the Free Software Foundation.[4] The license is used by Active Agenda, a risk-management web application, and NServiceBus, an asynchronous messaging library for the .NET/Mono platform.[5][6]
