Kevin, yes, I agree, although it gets even more ridiculous when the work
title is a URI, which then must be resolved to a string (except when the
work title is a string). The question, then, is what is the use case for
title as URI?

I'm not clear on what you mean here by the bf:Title construct. There is
a bf:Title class, which could help matters in some circumstances, since
one can search using rdf:type and therefore retrieve all predicates that
are sub-classes of bf:Title. At that point, however, the next step in
the SPARQL query would need to be the same for all titles to work
easily. Not knowing up front if the title will be a URI or a string
could make a difference in formulating a query.

It seems to me that the question is a bit different (or perhaps there is
yet another question) which is:

3) Do we need say things about the title? If so, it must be a "thing"
with a URI. If not, then it can be a literal string.

And an even bigger question:

4) Is there any of our data that can be a literal string, or must there
always be the option of saying something about the data itself? If so,
then our vocabulary becomes quite complex, and that will be evident in
the searches that can be run against it.

I wonder if we aren't imposing our closed world needs (e.g. the innards
of library systems, and of the library-to-library catalog data exchange)
with what will instead work best in a more open environment. If I wish
to link my authors or titles with, say, Wikipedia, what are my "data
about data" needs? Are they as detailed as the ones I would use to make
decisions about copy cataloging?
