Just as an FYI...
The VIVO project (www.vivoweb.org) uses SDB by default for its triple store.
The latest version of the software makes that someone configurable but I doubt
that many (if any) of the 80 something institutions that have deployed or are
developing a site using VIVO have used anything other than the default
configuration. Many of the organizations using it are major universities but
it also includes organizations such as the USDA, the Food and Agriculture
Organization of the UN, and the American Psychological Association.
