Abstract

We describe a minor change to the interpretation of UType values in VOTables, which helps document UType meanings, and makes it easy to relate UTypes to each other, supporting interoperability while requiring minimal standardisation. This makes possible simple but powerful reasoning capabilities, and we illustrate this with a resolver which makes the necessary capabilities available to applications with minimal cost.
