jup. have a look at www.gnowsis.org
we used CBD's to write simpler adapters than full graph implementations.
(ie http://www.wiwiss.fu-berlin.de/suhl/bizer/d2rq/)

if you download the latest release
http://www.gnowsis.org/statisch/download/gnowsis_0.8.1.zip
http://www.gnowsis.org/statisch/download/gnowsisSetup_0.8.1.exe

you find the source to many so called "CBD adapters"
we did an interface CBDEnhanced and used it throughout the whole 
application.
at the end, most of the system is somehow CBD enhanced and a single 
URIQA server on the side gives access to
* MSOutlook
* IMAP emails & folders
* filesystem
...
by the consequent use of CBDs and URL/URIs for identifying resources.

I am actually in writing a paper right now for ISWC about this topic, it 
is quite obvious from our view that writing adapters can be done in many 
ways and we have tested most of them, cbd is quite a quick start for it.

cheers
Leo
