Why Simple?
7
RDF gets the declarativity right, but is
losing its chance to get everything else right.
It should be focusing on making simple assertions
dirt simple for folks to sprinkle around, and
only after we get a critical mass of such
assertions should we worry about sophisticated
model issues. I think that in emphasizing a model
that only professors can understand, RDF is
making a similar error to XQuery If they
could just KISS, they'd be no-brainers, but
they're anything but.

Conclusions

• Triples can be used for low-level description
  within applications too
• They can be stored simply in a database
• They offer a flexible, yet controlled means of
  extending your data model
• Topic Maps and RDF are unnecessary for
  machine-consumed semantic data. Prove otherwise!
