We started to articulate and refine the long term vision for ARK identifiers, starting with the ARK specification by releasing a new Project Vision. It states: 

• We provide high-quality and affordable identifiers, supporting today’s and tomorrow’s scholarship

• We collaborate with libraries, archives, museums, publishers, research institutes, data centers, and educational institutions.

• We work openly to help the world to know itself through time by providing long-term access to global cultural and scientific heritage.
