Joe, as stated, the RDA rules are "technology neutral." I don't think 
that they say that a string can't be represented by an identifier so 
that one doesn't have to write "Penguin Classics" over and over again 
when recording the series, any more than it would state that one 
couldn't select a series title from a list of existing series titles. 
Any string that is likely to be repeated could be assigned an 
identifier. In fact, this is often what happens inside a database 
management system for repeated strings, especially those that are 
indexed, so it is already a fact of our existing systems.

One thing I think that we have failed to do (as a profession) is to 
bridge the gap between the intent of the cataloging rules and the actual 
functioning of the technology that will manage the data that is created 
in the cataloging workflow. If the cataloging rules require "recording 
series information", does that mean that the information is intended for 
display? for search? what kind of search? "Recording" doesn't answer 
those questions, but they do need to be answered. A lot happens, or 
should happen, after the cataloging data is created, and we don't seem 
to have a clear specification of what that is.
