Karen:

I agree, and these horizontal relationships are represented in MARC
records, if there at all, as textual notes.  This means that we can't rely
on legacy data as it exists now to be much help.  But the relationships
represented in this empty horizontal space are probably the best thing RDA
brings to the table, and we'd better figure out how to supply them ex post
facto, or we'll miss the real benefit of all this.
