jena - Assigning labels to triples -


i trying stream reasoning using jena, want able reason on set of triples have occurred in particular window of time, taking account background static knowledge.

my problem have ontology read several files, wish triples obtain have time stamps when receive them, thought applying labels triples (i giving them random time stamps moment test).

while didn't think problem, struggling @ initial step of applying label existing triple , selecting it. cannot not seem able access triples ontmodel without having transform graph, , while create quads value being literal time, can't find way reason on graph.

any light people can shed on issue help. hope being clear.

i'm not sure how you're putting labels on triples, can statements ontmodel, , statement implements frontstriple through can access corresponding triple.
