Reference Data

Reference Data - overview - ISO 15926 is modeled in a data-driven fashion, using templates that have "Roles", and where those Roles make reference to the URI of objects that have been declared as instances of the Part 2 entity types. The Reference Data Library, based on ISO 15926-4, stores concepts that are widely used in the user community.
