RDF study : so far it seems to be a problem of verbosity, and overallocation of significance to the concepts of subject, predicate, and object. Since there are no fixed definitions for { S, P, O }, it follows that there can be no fixed definitions for the relationships { SP, PO, } ( and by extension, SPO ). So the whole thing is just pointers, as binary functions, stacked to the 1st and 4th degrees.
( informal syntax scribling )
- SP and PO are just 1-ary pointers
- SPO is just a 2-ary pointer ( a pointer to a 1-ary pointer )
- SPOG is just a 3-ary pointer ( a pointer to a 2-ary pointer )
- SPOGM... is just a 4...-ary pointer ( ditto, etc. )
OK, back to reading. Now I have to try and falsify my hypothesis about this.
