RDA/ONIX Framework

The RDA/ONIX Framework for Resource Categorization provides sets of defined attributes of resource content and resource carriers and specified primary values for a subset of the defined attributes.

The Framework is used to derive content and carrier categories specified in RDA.

The Framework attributes and values are represented in the RDA Registry as:

The Framework is the basis of the RDA value vocabularies:

More specific RDA types use RDA refinements to RDA/ONIX value vocabularies:

The Framework is intended for use in a hub-and-spoke mapping architecture. Categories from each schema are mapped to concepts in the ROF value vocabularies, instead of directly to each other. Categories from two different schema can be mapped by matching the values of their ROF concepts.
