None. But that's not the Web.

IMHO, that's the mistake. There doesn't need to be a relational model of
data using URIs as keys.
Humans don't use URIs as keys.
Humans just want to write their information, *maybe* mark it up, *if
you're lucky*, and stick it out there. They don't want to model it. They
don't want to label it. They couldn't care less about URIs.
And that shouldn't (and doesn't!) matter. Search engines and other data
mining tools are quite capable of grabbing the data out of this free-for-
all. No need for any relational model.
Now, sometimes you do want to help the computers a bit, so that you can do
slightly more with it. That's where microformats like hCard and hCalendar
come in; they let you take data from well-known data formats (vCard and
iCalendar here) and publish that data directly in HTML in a way that can
be treated both as simple HTML, and as their original format (via a simple
reverse format translation) -- the latter of which lets you stick the data
straight into existing systems like your address book or calendar program.
But you don't need to go any further than that, IMHO. And certainly humans
don't want to go any further than that.
