About UOR Foundation

The UOR Foundation develops the Universal Object Reference specification — a formal ontology for content-addressed, symmetric, multi-metric object spaces.

Mission

To provide a rigorous, open, machine-verifiable specification for the algebraic structure of digital information, enabling interoperability across systems that represent, resolve, and transform computable objects.

What Is UOR?

UOR is a mathematical framework built on ring theory. Every computable object lives in the ring Z/(2^n)Z — integers modulo a power of 2. The framework specifies how objects are uniquely identified (content-addressed), decomposed (factorized under the dihedral group), and verified (certified by algebraic proofs).

The framework is encoded as an OWL 2 DL ontology with 34 namespaces, 474 classes, 948 properties, and 3601 named individuals. It is published in 7 serialization formats and as a Rust trait crate (uor-foundation on crates.io).

Conformance-First Design

Every claim this website makes is validated by the conformance suite — a set of automated checks that verify the ontology's structure, the website's content, and the generated artifacts. The website itself is generated directly from the ontology source, ensuring perfect alignment between specification and documentation.
