Why should there be anything like a so called "home resource" ?

All you needs is a URI (maybe you could see this as a starter URI or 
home URI, so to speak) and RESTful interactions (e.g. over HTTP) that 
enable a user agent deduce what's possible. In the course of such 
interaction, the server is also able to help user agents understand 
what's its capabilities are with regards to specific operations.

An example of a starter (or home) URI is a WebID. A URI that denotes an 
Agent (i.e., person, machine, software etc..). Given a URI one should be 
able to deduce what operations are possible in a given Web accessible 
(addressable) data space, associated with said WebID.

If you go back to Henry's examples, and pretty much his entire 
narrative, you'll see he is demonstrating how this is achieved using RDF 
-- within the constraints of existing Web Architecture.

RDF enables very precise data definition using an entity relationship 
model enhanced with explicit (machine comprehensible) entity 
relationship semantics. Again, none of that has anything to do with a 
specific notation for expressing subject-predicate-object triples (or 
3-tuples).
