One note: OpenCyc just by itself has several different URIs for Amsterdam.
This URI is from the 2008 release of OpenCyc. We recommend using the URIs
without dates for most purposes, in this case:

 http://sw.opencyc.org/concept/Mx4rvViJppwpEbGdrcN5Y29ycA<http://sw.opencyc.org/concept/Mx4rvViJppwpEbGdrcN5Y29ycA>

Hugh Glaser is kindly operating a "Coreference Resolution Service" [1] where
one can enter any OpenCyc URI and see the canonical version as well as
current alternative versions.
