The opening as it read in 2015
A community generated logo for open-source Judaism (credit: Dan "Moebius" Sieradski). Open-source Judaism is a name given to initiatives within the Jewish community employing Open Content and open-source licensing strategies for collaboratively creating and sharing works about or inspired by Judaism. Open-source efforts in Judaism utilize licensing strategies by which contemporary products of Jewish culture under copyright may be adopted, adapted, and redistributed with credit and attribution accorded to the creators of these works. Often collaborative, these efforts are comparable to those of other open-source religious initiatives inspired by the free culture movement to openly share and broadly disseminate seminal texts and techniques under the aegis of Copyright law . Combined, these initiatives describe an open-source movement in Judaism that values correct attribution of sources, creative sharing in an intellectual Commons , adaptable future-proof technologies, open technological standards, open access to primary and secondary sources and their translations, and personal autonomy in the study and craft of works of Torah. Douglas Rushkoff, who originated the term, consistently capitalized Open Source Judaism (see the citations in later sections). Open Source may be capitalized in recognition of the usage of The Open Source Definition as a trademark of the Open Source Initiative , although open source itself is not a trademark. When not referring specifically to Rushkoff's ideas, this article generally employs the lowercase, hyphenated form open-source Judaism , similar to the usual form for analogous movements such as open-source software and open-source religion .
