I finally checked the code of Backstage quickly. The class HostedDatabase (extending Database) seems to be responsible for the creation of the repository. Would that be imaginable to simply create another class (e.g. ExternalDatabase) extending Database that would, instead of creating a native store, connect to an external repository ? Something like :
_repository = new HTTPRepository(url, storeID); _repository.initialize(); _sail = ((SailRepository) _repository).getSail(); That seems like the easiest solution to me but I need the opinion of someone having actually work on this code :) On Jan 4, 2:13 pm, "Martin M." <[email protected]> wrote: > The triple store I'm using is actually Sesame+OWLIM and I've been > using the Sesame Java API to work with it.
