Hello John,    (01)

I have thought some more about this. I think every n-tuple alternative to RDF
that is not exactly like a RDB system:    (02)

-will be computationally more efficient than triples because tuple elements
 can be stored together    (03)

-cannot be as computationally efficient as a RDB as long as you have indices
 with mixed datatypes    (04)

-may not have a query language as simple as SQL as long as the tuple elements
 do not have fixed names.    (05)

You want n-tuples with a distinguished predicate position, perhaps also with
a distinguished subject position ?    (06)

Should the tuple elements have names or are they referenced by a position
number ? Should the tuple elements have fixed datatypes so that a tuple with
an element of wrong datatype is rejected ?    (07)

Both of these restrictions require a fixed schema that is known in advance or 
looked up from the predicate URI. I don't know if that would be a good idea.    (08)

Regards,    (09)
