AI's potential is limited by
data that is fragmented, lacks context,
and can't be trusted
We're solving this with the Universal Object Reference (UOR), a shared language framework for all kinds of of data. It helps AI consistently make sense of
and trust the information it processes.
Delivered through PrimeOS, powering the next generation of
AI applications that are context-aware and verifiable.

The UOR Foundation is a non-profit corporation based in Denver, Colorado, focused on advancing open research and building a global community of leaders in data science, AI and technology.
We're dedicated to creating open-source tools and standards that make data more reliable, transparent, and easy to work with. This work lays the foundation for
a trusted and interconnected internet of AI applications.
