From

:

I'm not quite understanding you're implying here.
IANAL (I Am Not A Librarian), just an end user, but
this still seems redundant to me.
Whether or not a work is a single thing, or a part of
a thing (such as an issue of a serial/periodical)
would be covered by a work's termination wouldn't it?

From FRBR (http://www.ifla.org/VII/s13/frbr/frbr.pdf):

It seems to me that WorkTypeTerms would be best used
in libdb_relationships_types.

Here's an example.
Tolkien's LOTR was conceived as a single work, but
published as a trilogy. LOTR:TFOTR is an expression of
LOTR. To map it out in LibDB:

libdb_work: 
title: LOTR
......................................
libdb_expression:
title: TFOTR
......................................
libdb_relationships:

referer_table: libdb_work 
relationship_type_id: ABC  
referent_table: libdb_expression
......................................
libdb_relationships_types:
id: ABC
name: AuthorSeries
subject: author series includes
object: is a part of author series
description: A collection of individual works that
form a series by a single author. Usually conceived of
as a series by the author, but can become a series
after publication. John Marsden's 'Tomorrow Series'
(http://www.austlit.edu.au/run?ex=ShowWork&workId=CoN))
is an example of author definition, while Martin
Boyd's 'The Langton Quartet'
(http://www.austlit.edu.au/run?ex=ShowWork&workId=C6dO)
was defined as a series after all four works were
published.
......................................................

I think this is a handy compromise from casual end
user to librarian and/or cataloger. Any thoughts?
