Markus, yes, this all makes sense to me, and it seems like a sensible

optimization. Let's discuss on today's call.

Subject: [xdi] new XDI operation $set ?

Hi,

Sometimes I find myself in situations in which I want to either add or

update a statement in an XDI graph.

E.g. I want to put the following statement into a graph

=markus

   +name

      "Markus Sabadello"

Today $add and $mod behave like this:

If I use $add, and the statement exists already in the graph, I get an

error.

If I use $mod, and the statement doesn't exist in the graph, I get an error.

Right?

I'd like to have an operation ($set) that always works, i.e. that behaves

like $add if the statement doesn't exists, and like $mod if the statement

exists.

So I could just do

=markus

   $set

      /

         =markus

            +name

              
"Markus Sabadello"

And I wouldn't have to worry if it exists already or not.

Does that make sense?

Markus
