hi=2C paul=2C
I would like to say=2C in my vision=2C the ideal rdf store will:=20
(1 )will differentiate with ontologies and instances of ontologies=2C
(2) all we have to do is to maintain ontologies to make them keeping up wi=
th continuously changing application requirement.
(3)the rdf store will do the synchronization between changed ontologies and=
instances almost automatically.=20
(4)solve the performance and scalable problem in large scale web applicatio=
n.
(5)light weight reasoning(optional) =20
if there is a rdf store fulfill above characters =2C i absolutely will make=
all my web development shift to it :-). =20
