Hi Holger,
Does TBC use Named Graphs inside of a TripleStore for AllegoGraph?
This is a question independent of which current version of AG that you
support. My initial assessment is that you don't, which is what
causes all my problems. I believe you just take the default,
"nameless" graph and use that for viewing and also when a model.owl
file (for instance) is exported to an existing AG TripleStore.
Something along the lines of:
("renew" if user selects to overwrite existing triplestore, "access"
otherwise)
AllegroGraph ts = ags.renew("cdmAG", "c:\\AllegroGraph\
\TripleStores\\");
ts.loadRDF("c:\\FileSystem\\Models\\model.owl");
GraphMaker maker = new AllegroGraphGraphMaker(ts);
Graph defaultGraph = maker.getGraph();
Model model = new AllegroGraphModel(defaultGraph);
What is curious/interesting is that there is a mechanic to add named
graphs (namely using the "target base URI" asked for by the export
dialog box). The use of a URI as the name for graphs within a triple
store is supported by the "preferred" method as demonstrated at
"com.franz.agjena.test.SimpleTest.main:352"
