Hello > Which implementations implement graphs (aka models) > as sets of statements (i.e. a graph may contain a > statement only once) and which implement graphs as > bags (i.e. a graph may contain a statement more > than once). RDFStore implements graphs/models as a mathematical set of statements. It associates a unique key to each statement by using a Skolem function carried out from the subject, predicate and object [1] (see URI generation for triples). Statements and model can be targeted by other statements [2] Yours Alberto [1] http://nestroy.wi-inf.uni-essen.de/rdf/sum_rdf_api/#K31 [2] http://lists.w3.org/Archives/Public/www-rdf-interest/2000Oct/0180.html
