Markus,
This subject has indeed come up several
times before. I know Bill has suggested that, when looked at from an RDF graph standpoint,
every XDI document can be represented as the set of RDF statements that appear
in the document. This would include all those whose object is a literal.
However when we refer to “the set of
XRIs” represented by an XDI RDF document, I have proposed that if the
object of an XDI RDF statement is a literal, the literal is NOT part of the
XRI. In other words, if you have the XDI RDF statement…
=markus
+email
""
…the XRI that identifies the literal
object of this statement (using direct concatenation syntax) is:
=markus/+email
That’s as far as we’ve gone
discussing it.
Is there any reason that rule will not
work?

Subject: [xdi] XDI graph as XRIs
Hey Bill,
I'm sitting together with Nat and Tatsuki, talking about various XDI topics.
One issue that came up was the following: I think it was you who suggested a
few times that every XDI document can be expressed as a simple list of XRIs,
right?
For example, if I have this XDI graph:
=markus
+friend
=bill.barnhill
=drummond
I could just express it using these XRIs:
=markus/+friend/=bill.barnhill
=markus/+friend/=drummond
Right?
Now the question is, how does that work with literals? If I have this:
=markus
+email
""
Then what's the XRI that represents this statement? I'm sure someone has
thought about that before, but I don't really remember how it works or if it
works at all?
Markus
