For established traditions whose canonical works, records of discourse, and inspired artworks reside in the
public domain, keeping these works open and available in the face of proprietary interests has inspired several open-source initiatives. Open access to resources and
adaptive reuse of shared materials under
open content licensing provide a structure by which communities can innovate new religious systems collaboratively under the aegis of copyright law. For some religious movements, however, public access and
literacy, and the potential of adaptive reuse also provide an opportunity for innovation and reform within established traditions. In an interview by
Alan Jacobs in
The Atlantic magazine on open-source religion, Aharon Varady (founding director of the
Open Siddur Project) explained that "cultures breathe creativity like we breathe oxygen" arguing that open-source provides one possible strategy for keeping a tradition vibrant while also preserving historical works as non-proprietary during a period of transition from analog to digital media.
Open-source Judaism Although a work of radical 1960s Jewish counterculture rather than an explicitly religious work, the satirical songbook
Listen to the mocking bird (Times Change Press, 1971) by
the Fugs'
Naphtali "Tuli" Kupferberg contains the earliest explicit mention of "copyleft" in a copyright disclaimer. Later open-source efforts in Judaism begin to appear in 1988 with the
free software code written for calculating the Hebrew calendar included in
Emacs. After the popularization of the term "
open-source" in 1998, essays and manifestos linking open-source and Judaism began appearing in 2002 among Jewish thinkers familiar with trends in new media and open-source software. In August 2002, Aharon Varady proposed the formation of an "
Open Siddur," an open-source licensed
user-generated content project for digitizing liturgical materials and writing the code needed for the
web-to-print publishing of
Siddurim (Jewish prayer books). Meanwhile, media theorist
Douglas Rushkoff began articulating his understanding of open-source in Judaism. "The object of the game, for me," Rushkoff explained, "was to recontextualize Judaism as an entirely Open Source proposition." The term "Open Source Judaism" first appeared in
Douglas Rushkoff's book
Nothing Sacred: The Truth about Judaism (2003). Rushkoff employed the term "Open Source" to describe a democratic organizational model for collaborating in a commonly held source: the
Hebrew Bible and other essential works of
Rabbinic Judaism. Rushkoff conceived of Judaism as essentially an open-source religion which he conceived as, "the contention that religion is not a pre-existing truth but an ongoing project. It may be divinely inspired, but it is a creation of human beings working together. A collaboration." For Rushkoff, open-source offered the promise of enacting change through a new culture of collaboration and improved access to sources. "Anyone who wants to do Judaism should have access to Judaism. Judaism is not just something that you do, it's something you enact. You've got to learn the code in order to alter it." The 2003 publication of Rushkoff's book
Nothing Sacred: The Truth about Judaism and an online forum dedicated to "Open Source Judaism" inspired several online projects in creating web applications for generating custom made
haggadot for
Passover, however neither content nor code for these were shared under
free-culture compatible open content terms. Beginning with the
Open Siddur Project in 2009, open-source projects in Judaism began to publicly share their software code with open-source licenses and their content with
free-culture compatible open content licenses. The explicit objectives of these projects also began to differ from Rushkoff's "Open Source Judaism." Rather than seek reforms in religious practices or doctrines, these projects used Open Content licenses to empower users to access and create their own resources from a common store of canonical texts and associated translations and metadata. By 2012, open-source projects in Judaism were mainly active in facilitating collaboration in sharing resources for transcribing and translating existing works in the Public Domain, and for adaptation and dissemination of works being shared by copyright owners under Open Content licenses. In Open Source Yoga Unity v. Bikram Choudhury (2005), the organization settled out of court, avoiding a federal court hearing to determine whether Bikram Choudhury's copyrighted sequence of 26 poses and two breathing exercises could be legally protected.
Open-source Wicca Concerned with the lack of a source text containing documentation on
Wicca in the tradition of
Gerald Gardner, Dr.
Leo Ruickbie self-published
Open Source Wicca: The Gardnerian Tradition (2007) for "putting you back in control of spirituality." The work, a collection of "the original foundation documents of Wicca" authored between 1949 and 1961, was published digitally and in print under a
