Element	`https://uor.foundation/u/Element`	`http://www.w3.org/2002/07/owl#Thing`		A content-addressable ring element. Each Element uniquely identifies a piece of content via its hash-derived identifier.

Name	Kind	Functional	Domain	Range	Comment
length	Datatype	true	`https://uor.foundation/u/Element`	`http://www.w3.org/2001/XMLSchema#nonNegativeInteger`	The number of Braille glyphs in an address string.
addresses	Object	true	`https://uor.foundation/u/Element`	`http://www.w3.org/2002/07/owl#Thing`	The datum that this address references. Inverse of schema:glyph.
digest	Datatype	true	`https://uor.foundation/u/Element`	`http://www.w3.org/2001/XMLSchema#string`	The content hash of this address. Format: (blake3\|sha256) colon followed by 64 lowercase hex characters. The algorithm prefix must match u:digestAlgorithm.
digestAlgorithm	Datatype	true	`https://uor.foundation/u/Element`	`http://www.w3.org/2001/XMLSchema#string`	The hash algorithm used to produce u:digest. Allowed values: 'blake3' (primary), 'sha256' (secondary).
canonicalBytes	Datatype	true	`https://uor.foundation/u/Element`	`http://www.w3.org/2001/XMLSchema#hexBinary`	The canonical byte serialisation of the addressed datum, per Amendment 43 section 2: header(k) \|\| le_bytes(x, k+1). This is the exact byte string hashed to produce u:digest.
wittLength	Datatype	true	`https://uor.foundation/u/Element`	`http://www.w3.org/2001/XMLSchema#positiveInteger`	The Witt level n of this element. The element encodes a datum in R_n = Z/(2^n)Z.
