The Structure of a Book in the Sefaria Library

Quick Notes on Indexes and Versions in the Sefaria Library

Each book in the Sefaria Library is represented by a unique Index. Each book has one, and only one, Index associated with it.

Each version of a text (a translation, a different edition, etc.) is represented by a Version object. While it's possible for an Index to have no Version objects associated with it, this is not generally the case. More commonly, each Index will have at least one Version object associated with it.

For more information about the Index and Version structures, see Index and Versions.

Each Index is supported by a schema which represents the structure of the book in question and provides important relevant metadata and structural information.
