Also begin populating values in the intermediate definition.
TODO: Replace the hack in the spec definition with something applicable
RDF-wise (is there anything that permits this RDF wise?).
- Fixed the way indexing nodes were being applied
- Implemented property types in ontologies
- Improved class types in ontologies
- Lots of other stuff
Also adds some placeholders for the schema ontology.
Eliminated some dead code in the RDF manager thing.
Next step is to get mainEntity parsing to ignore the rest of the values,
which should be easier to do, maybe.
