if you'll notice, i said, "et al", which means that Cole, Shreeves, "and
other people on the DCC IMLS project" have published their analysis of
metadata usage in the OAI-PMH. :-) :-)
in the URL above, under "publications" and
"presentations", you'll see pubs and presentations dated between 2004 and
2008. my study, completed in 2002, examined metadata usage in 2001-2002.
i believe that between the initial experimentation when UPS was developed
==> the OAI-PMH (1999-2001), my study (2001-2002, published 2003), Dushay
& Hillmann's (published 2003) study, and the DCC IMLS study (2004-2008),
among others, we have both anecdotal and formal evaluations of metadata
usage and quality related to the OAI-PMH over a 9 year period.
Margaret Alexander wrote me off list and told me I should cite my study,
so here it is:

do i think the OAI-PMH framework or was dead? no. hence, posting these
emails. but i do think it is going to continue evolving, per OAI-ORE, etc.
the lack of shareable, quality metadata has been a barrier
to using the framework to "its fullest extent", as the lack of quality
metadata has limited the kinds/types/amounts of services that can be built
on it. yes, there have been hurdles to overcome, but it has been 5-6 years
since the first formal studies came out on the lack of shareable quality
metadata, and that has given some time to improve on what is out
there...and that hasn't happened. Rachael Heery mentioned to me at the
JCDL in 2003 that she had done an an informal study at some point in the
1990s (unpublished) in which she found similar results to my study
published in 2003. in other words, this has been a known problem for a
while, even if the results have been more informal and anecdotal.
does that mean i think metadata is dead? no. just that there is a known
need for improvement, but given the limited resources of libraries, that
is not likely to happen in an optimal manner.

whether or not one "implements" the OAI-PMH depends on what software
you use; not everyone uses ePrints/DSpace/Fedora. in which case, they
"implement" the protocol b/c it is not built-in, unlike SMTP in mail
servers, to work w/their specific dl/digital archive software. while use
of the word, "implement" may be a misnomer, it has long been used in the
protocol specs and the tutorials and forums on use of the OAI-PMH.

yes, i did in this email:

(rather than repost what i have already written.)
