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.
Unencumbered access to educational resources, the importance of attribution, and limiting proprietary claims on intellectual property, are all matters common to open-source, the free culture movement, and rabbinic Judaism. Open-source Judaism concerns itself with whether works of Jewish culture are shared in accord with Jewish teachings concerning proper stewardship of the Commons and civic responsibilities of property ownership.
The rhetorical virtue of parrhesia appears in Midrashic literature as a condition for the transmission of Torah. Connoting open and public communication, parrhesia appears in combination with the term, (dimus, short for dimosia), translated coram publica, in the public eye, i.e. open to the public As a mode of communication it is repeatedly described in terms analogous to a Commons. Parrhesia is closely associated with an ownerless wilderness of primary mytho-geographic import, the Midbar Sinai in which the Torah was initially received. The dissemination of Torah thus depends on its teachers cultivating a nature which is as open, ownerless, and sharing as that wilderness. Here is the text from the Mekhilta where the term dimus parrhesia appears (see bolded text).
