Survey on usage of Reified Statements?

Has anyone done a survey on how RDF reified statements
are used in practice?  I'm looking for answers to the
following questions:

Assuming that your application/model/knowledge base makes
systematic use of reified statements (its not just an
example for a primer or a test application):

Do you attach metadata repeatedly to each statement, or
do you put groups of statements into an RDF container (or other
collection) and attach metadata to the container?

How many metadata statements on the average are attached
to each reified statement?

If you do group reified statements into containers/collections/contexts,
how many statements per container are there, and how many containers
per model?

If people reply only to me (rather than rdf-interest) that will
reduce e-mail traffic (assuming I get some responses).  I will
broadcast the results I get after a few days of waiting.  If
someone has already done such a survey, please let me know.

Cheers, Bob
