Jeff, now that you mention this I am struck with grave doubts. ;-) The Wikipedia URI may be considered to represent the work, as would be dbpedia URI, but the Wikipedia page is not a commonEndeavor with the work. This is where we get back to your arguments about 303's -- but I'm not convinced they save us in this case. The Wikipedia URI represents the topic AND the page, but can you say that a book is an "instance" of a Wikipedia URI? Too philosophically difficult for Sunday a.m. kc On 1/26/13 7:30 PM, Young,Jeff (OR) wrote: > Karen, > > The thought that a Wikipedia page could be considered to represent the > Work has been bugging me for awhile too.
