The proliferation of content in electronic format and other emerging technologies was a chief impetus in the creation of the Functional Requirements for Bibliographic Records, the ISBD Area 0, and the development of RDA: Resource Description and Access. RDA in particular relies upon extensive sets of small vocabularies used in bibliographic data elements to describe carriers and content. These vocabularies provide a foundation for universal bibliographic control that supports Linked Data. However, some established technologies do not have appropriate vocabulary terms in RDA, relegating these resources to an undocumented area of description that inhibits universal bibliographic control. In conclusion, there are some methods for updating data element vocabularies in RDA. Review of emerging technologies by a committee designated for such oversight may aid universal bibliographic control as technologies are introduced and adopted.
