Good Day,
I have several different files that are stored in separate TDB folders. I
want to bring them all together to create a model that is easier to search.
I currently know how to name each of the TDB folders as named graphs, but I
believe my code is extremely inefficient. I would appreciate any advice on
how I can make this more efficient or use some of the statements that are
already available that will make things more straightforward. I have added
what I am doing currently. It works, but seems like a workaround. I
appreciate your time and assistance.
String fileNameOrUri = "TDBStore/Test0/triples0000.nt";
String fileNameOrUri1 = "TDBStore/Test1/triples0001.nt";
String directory0 = "TDBStore/Test0" ;
String directory1 = "TDBStore/Test1" ;
// To read quad
* TDB.getContext().set(TDB.symUnionDefaultGraph, true);*
Dataset dataset0 = TDBFactory.createDataset(directory0) ;
Dataset dataset1 = TDBFactory.createDataset(directory1) ;
* Model model0= dataset0.getNamedModel("urn:x-arq:UnionGraph");
Model model1= dataset1.getNamedModel("urn:x-arq:UnionGraph");*
* //merge the graphs
Model modelf = model0.union(model1);*

Does each TDB dataset contain one single graph or many?
It's only going to be more efficient if you can put all the data into
one database.
If you can, put all the graphs into separate named graphs in one
database and use "urn:x-arq:UnionGraph".
