Hello,
1. we wish to make an application that stores relations basically
subject-predicate-object
For example : Force-dependson-mass, Force-dependson-acceleration,
whale-isa-mammal.
2. What we have decided is to make separate persistent class for each
predicate. For example
in the examples given above we have two predicates "dependson" and "isa".
3. (defpclass dependson ()
((subject :accessor subject)
(predicate :accessor predicate)
(object :accessor object)))
4. How do I index a slot so that later if I have a query where I have been
provided with two slot values I should be able to get the third slot value.
For example: Force-dependson-? should return "mass" and "acceleration".
We are refering to the elephant.pdf downloaded from the documentation
section
of the elephant website
Thank you
Arjun Mullick
