Hi, David! I haven't caught up on the mailing list yet, so apologies if
I'm repeating what's been said.

I understood this to mean that they were adopting the RDF philosophy
(flexible data structures, pervasive URIs, fully-extendible
descriptions of everything); I certainly hope they aren't planning to
store it as RDF/XML.
RDF is sort of a natural way to think of this data, but that doesn't
mean the APIs need look like addTriple, getTriples (indeed, my TRAMP
library for Python makes RDF look like regular objects) nor that the
storage format encode things in RDF. There are many APIs and backends
that can be used without sacrificing the flexibility of the philosophy.
The important features to me are that everything is intertwingled, with
links from mail to address book to recent messages to calendar appoints
everywhere, and that I can always add more attributes and values to
nodes. In this sense, the RDF philosophy is that we make simple
statements (this email is about the Chandler project; this folder
should show all messages about the Chandler project) rather than
placing things in some sort of hierarchy (new folder with name
Chandler; move this email to the Chandler folder).
