Who we are

The Open Siddur is an open source project and anyone can join by helping to code, transcribe, translate, scan books and facsimile editions, and compose new work shared with a free culture license. The project is non-denominational and non-prescriptive. What unites us is our intention to share our work on the Siddur and in Jewish spiritual practice. We come from many different backgrounds but share a passion for making the ingredients of the Siddur freely available.

Want to help with this project? We need folks to transcribe, translate, scan books and facsimile editions, code, and share work they’ve already written or illustrated using copyleft and free culture licenses. Communication is key in an Internet-based project like ours, so please take our survey and join our discussion list by first introducing yourself. Please don’t be shy. A table listing volunteer opportunities by skill set is here. We also accept financial donations using Razoo through our fiscal sponsor, the Center for Jewish Culture and Creativity, a registered 501(c)3 nonprofit. A full list of the good people sharing their time and creativity by contributing to the project are listed here.

The Open Siddur Project is part of a growing number of Jewish organizations adopting open source strategies for sharing its creative work under free-culture compatible open content licensing. Regardless of whether you share your content with the Open Siddur, we invite you to share your work with open content licensing. In any case, please contact us so that we can help signal boost your project!

Moshe Ben Maimon

Mosheh ben Maimon (משה בן מימון), called Moses Maimonides (/maɪˈmɒnɪdiːz/ my-mon-i-deez) and also known as Mūsā ibn Maymūn (Arabic: موسى بن ميمون‎), or RaMBaM (רמב"ם – Hebrew acronym for "Rabbeinu Mosheh Ben Maimon" – English translation: "Our Rabbi/Teacher Moses Son [of] Maimon"), was a preeminent medieval Spanish, Sephardic Jewish philosopher, astronomer and one of the most prolific and influential Torah scholars and physicians of the Middle Ages. He was born in Córdoba (present-day Spain), Almoravid Empire on Passover Eve, 1138, and died in Egypt on December 12, 1204. Although his writings on Jewish law and ethics were met with acclaim and gratitude from most Jews, even as far off as Iraq and Yemen, and he rose to be the revered head of the Jewish community in Egypt, there were also vociferous critics of some of his writings, particularly in Spain. Nevertheless, he was posthumously acknowledged to be one of the foremost rabbinical arbiters and philosophers in Jewish history, his copious work comprising a cornerstone of Jewish scholarship. His fourteen-volume Mishneh Torah still carries significant canonical authority as a codification of Talmudic law. In the Yeshiva world he is called sometimes "haNesher haGadol" (the great eagle) in recognition of his outstanding status as a bona fide exponent of the Oral Torah. (from "Maimonides" on wikipedia)
