One vote here for the latter as well. The first is more about  
presentation then content, that's a client side issue. We could pass  
the latter through XSLT to get the former for some HTML clients...

I'd like to see. I think these discussions also tie into any schema  
changes if needed, etc. I've also pasted some text from an OWL ontology  
(OWL is built on top of RDF). Nice thing there is you can also define  
the relationships between the data. With plants being the basic  
objects, relationships aren't hugely important, but if we plan to move  
on to broader subjects, microfuana, etc, they'd start to come in handy.  
It's also nice that you can layer definitions on top of each other, not  
sure if DTD does this.
