RDA 3.0

RDA 3.0: GMD to CMC Conversion

This phase of RDA processing comprises a series of routines that compare existing GMDs (245 $h) as well as specific positions of the leader and fixed fields to determine the best RDA Content Type RDA 6.9 (RDA), Media Type RDA 3.2 (RDA), and Carrier Type RDA 3.3 (RDA) types to add to the 33X fields in your records.

Sample GMD to CMC conversion table

Here is a sample GMD to CMC conversion table. The full table consists of over 600 different variations. Fields taken into account in adding the 33X include the Leader, 007, 008, 245 $h and 300 $a.

If your local practices for assigning GMD or CMC differ from MARS 2.0 processing, please contact your project manager to discuss options for altering the way GMDs and CMCs are processed in your records.

Note: Custom mappings can also be generated upon request.
