When describing physical carriers, RDA provides data elements for technical details such as Base Material, Generation, Polarity, Sound Characteristic, Video Characteristic, etc.

Previous work on a mapping from RDA to BIBFRAME showed there is no immediately obvious way to treat these technical details in BIBFRAME when mapping directly from RDA. This situation differs from MARC encoding of carrier technical details, where they are part of MARC fields that have a more obvious mapping.

This proposal describes a way to treat carrier technical details in BIBFRAME using existing properties and classes. While it focusses on carrier details in RDA, it should work with other cataloging codes.

The proposal, which was written by Theo Gerontakos and me,  is attached and also available at:
