We call our Siddur Project "open" because we adhere to the definition of open content and open data as maintained by the Open Knowledge Foundation.
Project contributors make their copyrighted work available for adaptive reuse in other open-source siddurim, curricular resources, and Torah databases under any one of these three Open Content licenses:
תלמוד ירושלמי ברכות (ב:ד): רבי בון ב״ר חייא אמר אנא מנית דימוסיא.
Sefer Yetsirah (40):
Two stones build two houses;
three build six houses;
four build twenty-four houses;
five build one hundred and twenty houses;
six build seven hundred and twenty houses;
seven build five thousand and forty houses.
From here on go out and ponder
what the mouth cannot speak,
and what the ear cannot hear.
The Open Siddur is an expression of open-source Judaism. We are a G'MaḤ (lending society) for tefilot (prayers) and related text and art. Transcribe or translate a prayer and share it. Help us develop our software. If you can't share a text or code, then please help us by telling others about this project or by donating some money to help us pay someone else to pick up the slack. Every shekel, drachma, or dollar you contribute helps to liberate the ingredients of Jewish spiritual practice for all collaborating free/libre and open source initiatives. Your tax deductible donation will help us afford to maintain this website, grow this project, and complete our web application.
The Open Siddur is a program of the Jewish Free Culture Society and is crowdsource funded through small donations through our fiscal sponsor, the Center for Jewish Culture & Creativity, a 501(3)c registered non-profit organization. Additionally funding is provided by Dimus Parrhesia Press, a publisher of Jewish theurgy smuggled from across the River Sambatyon.
The views expressed in contributed works represent the views of their creator(s) and do not necessarily represent the views of the Open Siddur Project's developers, its diverse community of contributors, the Jewish Free Culture Society, or the Center for Jewish Culture & Creativity.
