Hierarchical Structure

Store hierarchical structure of texts and use it for references and retrieval of text fragments. Examples: Tanach - book, chapter, verse; Chumash - weekly portion; Chumash - parsha (with type - open/closed); Rashi on Tanach: book, chapter, verse, comment; Mishna: treatise, chapter, mishna; Talmud: treatise, folio, side; Talmud - treatise, chapter, statement; Rambam: [book,] laws of, law, statement; Shulchan Aruch: division, chapter, paragraph, small paragraph…​

Store page (and line) breaks for multiple editions of the same text.

A text can have multiple hierarchical structures, some of which can be incompatible with one another: parsha can end inside a verse, weekly portion - inside a chapter, page break can be inside a sentence…​

Some texts have the same structure, although they are not commentaries on one another, e.g.:

  • original and translation
  • different editions of the same text
  • Shulchan Aruch and Shulchan Aruch HaRav

We need to be able to combine texts with the same structure - e.g., parallel translation. Specific edition gets chosen based on the user preferences: language, presence of vowel points etc.

We need to be able to show differences between different editions of the same text - in a form of a text, with differences highlighted :).
