In addition to text that we carefully transcribe and proofread from works in the Public Domain, our community of contributors make their own copyrighted work available for your adaptive reuse under their choice of Open Content license. We posit that the resources and technologies necessary to engage in the most fundamental activities of Judaism be accessible, gratis (without cost) and libré (without restriction), for all its voluntary participants and educators. Thus, we believe that everyone engaged in the practice of Jewish prayer should be empowered to craft their own prayerbooks with open-source publishing technologies and open content licensed prayers (and not be limited by proprietary technologies or content). One committed at heart to the craft of their own prayerbook should really only be limited by their knowledge of prayers and liturgical customs.

We envision a world where prayerbooks are not only treated as containers of Jewish identity and spiritual heritage, but also as open-source repositories of effective exercises, prompts, and methods – shared praxes – for growing the creative and emotional intelligence in the individuals and communities who choose to utilize them in their committed practice. Our commitment to collaboration and sharing is why we call our siddur project 'OPEN.' We aspire to be a resource of Jewish prayer as freely shared as the Torah of Kindness (תּוֹרָת חֶסֶד) described in Sukkah 49b:11-13, transmitted as openly and earnestly as the Torah was shared in the Midbar Sinai, as free a resource for all who enter into the world as fire, water, and wilderness (cf. Mekhilta de Rebbi Yishmael on Shemot 20:2, §Baḥodesh). Just as the otherwise ephemeral world of scholarship and creativity is sustained by the acknowledgment implicit in proper credit and attribution, so too is the vitality of this heartfelt collective. All these offerings of words, insight, and ritual praxis graciously shared by those "whose hearts have been stirred" (cf. Exodus 36:2) have been made with the expectation of attribution as explicitly stated in the rabbinic Jewish requirement concerning the proper transmission of oral teachings: they must be shared in the name of the one from whom they were received (cf. Avot 6:6, Megillah 15a:20). In this way, the lineage of the source is preserved, the creator is honored, and the lattice of kindness supporting the selfless creative act is reinforced.

For these reasons, our project values are also aligned with the definition of open content and open data maintained by the Open Knowledge Foundation, the definition of open-source maintained by the Open Source Initiative, and the four values of libré/free culture maintained by the Free Culture Foundation. ☞ Read more in our copyright policy.
