Now as a part of RDA processing performed during authorities processing, we have the ability to create fields that can assist with formulating format facets, and prepare for linked data.    These new 34X fields provide consistency in describing the characteristics of various formats.  They are:

340      Physical Medium
344      Sound Characteristics
345      Projection Characteristics of Moving Image
346      Video Characteristics
347      Digital File Characteristics
348      Format of Notated Music

The conversion is only as good as the data elements that typically are already present in the MARC record in various fields and subfields.  Our processing looks at the LDR, 007, 008, 300, 533, and 538 fields to accurately create the new 34X fields.

Libraries looking to do authorities processing and RDA conversion on their legacy cataloging records can have this new processing included.  Existing customers can request that we add this option to any new bibliographic records sent for processing.  And even better yet—Comprehensive Notification customers can have this option applied with their next processing run—essentially having the entire backfile performed to include new RDA tags.  There is no additional charge for this option.

Here are some examples.
