Part of the Information Management Framework; The Reference Data Library is the particular common set of classes and the properties we will want to use to describe our digital twins. In practice, this could take form through a federation of domain-specific libraries, with a single common protocol.
The specifics of particular controlled vocabularies (taxonomies) and how common words are used, providing standardised choices for differences arising from sectoral and disciplinary legacies.
Many of these definitions and properties already exist, and in some cases we can use automated tools, such as semantic data mining, to help to collate them.
Reference libraries do not remove the need for subject-matter experts to interpret the results and extract policy insights or commercial decisions. Furthermore, multidisciplinary skill sets must be fostered to interpret results that span the boundaries of traditional disciplines.
