Hi Kingsley, Pat and all,

> Chris/Anja: I believe this data set was touched on your end, right?

Yes, Anja will fix the file and will send an updated version.

Pat: Your comment seems to imply that you see the Semantic Web as something
consistent that can be broken by individual information providers publishing
false information. If this is the case, the Semantic Web will never fly!

Everything on the Web is a claim by somebody. There are no facts, there is
no truth, there are only opinions.

Semantic Web applications must take this into account and therefore always
assess data quality and trustworthiness before they do something with the
data. If you build applications that brake once somebody publishes false
information, you are obviously doomed.

As I thought this would be generally understood, I'm very surprised by your
comment.

Cheers,

Chris
