caBIGDomainObject_attribute_valueDomain

A critical notion in the caBIG metadata model is that “any concept represented by a data element must have an explicit definition that is independent of any particular representation”.  In order to achieve this in the model, the ISO/IEC 11179 standard specifies a ConceptDomain which is a set of all indended meanings for the possible values of an associated DataElementConcept and the ValueDomain is a set of accepted representations for these meanings.  See: https://cabig.nci.nih.gov- /guidelines_documentation- /caGRIDWhitepaper.pdf
