11. Goals of DC-Lib Redux Serve as interchange format Use for harvesting metadata Support simple creation of catalog records Expose MARC data to other communities Enable import of non-MARC resource discovery metadata

12. Can DC-Lib meet its goals? Does its complexity inhibit its usefulness? Does it provide an adequate middle-level of access between MARC/AACR2 and unqualified Dublin Core? Does it “dumb down” successfully? Are there other concerns regarding DC-Lib?
