Re: [RDA-L] RDA promoting the work entity?

2012-10-18 Thread Jonathan Rochkind
The title statement has never been that optimal for collocating works, 
because even when it's not been left to cataloger judgement but has been 
recorded according to very specific rules -- they were rules based on 
how the title was printed on the item-in-hand (manifestation), which 
isn't neccesarily uniform accross works. Still, some algorithms try to 
make use of the 'title proper' in collocating works anyway, but it's 
very imperfect. I don't think allowing more cataloger judgement in 
manifestation 'title proper' will make things much worse for work 
collocation based on title proper (although i could be wrong).


I think you're exactly right that some kind of 'authority file' (which 
contemporarily might be called simply a 'work identifier' instead) is 
the key to collocating works. But I am also not quite sure how 'we' get 
from here to there. But I don't see changing standards for title proper 
probably being an impediment.

The current NAF does include records for expressions, and those include 
much, much more than literary works.  Two of the most obvious are sacred 
religious texts and musical works (including operas and ballets). 
Scientific texts also have different expressions: the Latin and 
vernacular expressions may have significant differences while successive 
editions of texts might be better treated as expressions rather than 
separate works.


I'm not going to say that providing ways of distinguishing expressions is 
THE most urgent task, but it is one of the things that RDA will do better 
than our current very mixed system of authority records for works and some 
expressions.

Certainly compared to just being able to collocate works, and present a 
search results where manifestations of the same work are grouped together 
under one entry -- that's something most of our systems still can't do, and I 
think a LOT higher priority.

 Once you've collocated by work, simply displaying a list of items under
 that work grouped by _format_ is probably more useful than by expression
 (the majority of works will only have one expression, but many of these
 will still have multiple formats; print, audiobook, online, etc.)


Print and audiobook would constitute different expressions, each of which could 
be found in different manifestations.

With print, revisions and different language versions would constitute 
different expressions, and with audiobook, different narrators would constitute 
different expressions.

Solving the problem with grouping works shouldn't mean ignoring the problem 
with grouping expressions-- one would think solutions for consistent data 
should apply across the board.

It seems to me we need to be flexible about expressions in our data models.

Some cases warrant a record (or data) that identifies a specific expression; 
but others (like, for example the expression that results from a translation of 
another expression into a different language) it may be sufficient just to 
identify a category of expression.

VIAF already contains records for Works and Expressions. Search for Nachtmusik 
for some examples. A catalog with entries for Works and Expressions is feasible 
and would remove the need for computers to comb through data. The research by 
OCLC proved that based on current records, computers are not able to 
distinguish between Expressions, which is the biggest added value to Identify 
and Select.
