Interesting project. Just a word of caution: Note that DBpedia isn't an ontology. From an ontology point of view, DBpedia is just a bunch of instances, without a nice well-engineered class hierarchy. Two different experimental class hierarchies are available for DBpedia (YAGO and CWCC), but both have their flaws, are very complex, and I wouldn't say that they represent the "natural order of things" -- maybe rather the "natural disorder of things" ;-) > I have a query with regards to how I actually should interact with > the system.

Which dumps to choose depends of course on the data that should be available to answer the queries. If you don't need links to images or chinese titles, then you can skip the Images and Titles/zh dumps ... > And what would be the most efficient way to interact with the local > source? You will need to install a triple store that supports SPARQL, then load the dumps into the store, and then you can write your application so that it queries your local store instead of the online DBpedia endpoint. I can't give a recommendation for a specific triple store, but the online DBpedia endpoint runs on OpenLink Virtuoso.
