It is more or less meaningless to have an explicit type of rdfs:Resource, and
some tools don't like it, since everything (including classes and properties)
is a Resource.  Since this is an individual, owl:Thing is a better type.

This was obviously wrong.  I'm not sure how this happened, probably a
copy/paste mistake.

For consistency, and because clang-tidy can't figure out if a define is an
include guard unless it ends the file.

Not all of these actually show up in the output, but it's unnecessary to use
these in Markdown anyway.
