Graham, I'd advocate using WorldCat Identities to get to the appropriate url for dbpedia. Each Identity record has a wikipedia element in it that you could use to link to either Wikipedia or dbpedia. If you want to see an example of this in action you can check out the Author Info demo I did for code4lib 2010 here - http://www.librarywebchic.net/mashups/author_info/info_about_this_author.php?OCLCNum=32939031 The code for this demo is available for download at - http://www.worldcat.org/devnet/code/devnetDemos/trunk/ You'll want the author_info folder and identity_info.php Karen Karen A.
