//! Vocabulary types generated from Fedify's schemas.
//!
//! Do not edit this file. It is written by `cargo run -p ojak-vocab-gen`
//! from *crates/ojak-vocab/schemas*, which are Fedify's work under the MIT
//! license in that directory, and a test fails when it differs from what the
//! generator would write now.
//!
//! Each type reads a document in the form [`crate::read`] produces and writes
//! one in the same spelling. A property that may take several types takes an
//! enum of them, with `Iri` for a reference and `Other` for anything no
//! schema describes.
