[Evergreen-catalogers] RDA and the future of Evergreen

[Hardy, Elaine]

There isn't as of yet, that I have heard of. One of the problems with a
conversion matching is that not everything would be a one-to-one because
either AACR2 doesn't require it, or one MARC field can have several bits
of information that would be separate entry in RDA. For example, for some
of the carrier types, it is best expressed in an 007; but 007 isn't a
required field so not all records that should have them do. And, the
values in an 007 mean different things depending on the record format --
007 |g for a map is Production/ reproduction details. The same subfield
for video recording is 	Medium for sound.

Given a (non-brief) AACR2 record, is there a set of rules published for
mechanically deducing the RDA carrier type?  If so, a filter potentially
could be expressed in terms of the 338 for RDA records and the calculated
carrier type for AACR2 records.
