Hi Pat,

We're definitely interested in improving the quality of our owl:sameAs links
to DBpedia and other datasets. In this case, however, I believe the
owl:sameAs link is good -- it's the OpenCyc comment that's bad. The URI
opencyc:Carbon <http://sw.opencyc.org/concept/Mx4rvVjIQpwpEbGdrcN5Y29ycA>denotes
an owl:Class representing the element carbon. Its instances are
individual pieces of carbon, including diamonds and lumps of coal. We'll get
the comment fixed.
