Umm, I don' think the RDF above is well-formed because it contains
many occurrences two undefined entities (&xsd; and &owl;). I suppose
someone will want to declare these entities at the top of the RDF
file, but I don't know how to do that. (Sigh.) Alternatively, maybe
these entities were really suppose to be namespaces? In which case
xsd was not defined and all the of the occurrences of &owl; should be
changed to owl:.
I find that a pair of tools called xmllint and xsltproc are VERY good
for validating and transforming XML, respectively. These utilities
run on Windows as well as Unix (Linux/Macintosh) computers. I also
find the RDF Validator to be a useful tool. [1] When the RDF is
valid, it outputs cool graphs literally illustrating how things are
related to each other.
