API Interaction
---------------



1) Using the Tinkerpop Blueprint API's

a) The graph structure


	public static AmilInterpreter getInterpreter() {
		if (interpreter == null) {
			interpreter = new AmilInterpreter(dbName);
		}
		interpreter.index().getNodeAutoIndexer().startAutoIndexingProperty("value");
		return interpreter;
	}


		System.out.println("OWL node properties  = " + getInterpreter().getNodeById(171).getPropertyKeys());
		System.out.println("OWL link name  = " + getInterpreter().getRelationshipById(356).getType().toString());

The test run in SparqlTest.java gives ths:

OWL node properties  = [kind, value]
OWL link name  = http://www.w3.org/1999/02/22-rdf-syntax-ns#type

N.B. I have trid ed to get indexing of "value property" ... see

		interpreter.index().getNodeAutoIndexer().startAutoIndexingProperty("value");

b) loading data:

private static InputStream getOntologyFile(String filename) {
       return SparqlTest.class.getClassLoader().getResourceAsStream(filename);
}

InputStream file1 = getOntologyFile("ontologies/amil.owl");	
sailgraph.loadRDF(file1, "http://projects.baesystems.com/META", "rdf-xml", null);

c) SParql querying

String query1 = "PREFIX cfv: <http://projects.baesystems.com/META/ontology/2011/8/cfv#> SELECT ?engine WHERE {?engine a cml:Engine .}";

		SailGraph sailgraph = getSailGraph();
				try {
			List<Map<String, Vertex>> result1 = sailgraph.executeSparql(query1);
			System.out.println(result1);
				}
				catch (Exception e) {
					System.err.println("Error on query1: " + query1 + ": " + e.getMessage());
				}


Returns

[{engine=v[http://projects.baesystems.com/META/ontology/2011/8/cfv#CFVEngine1]}, {engine=v[http://projects.baesystems.com/META/ontology/2011/8/cfv#CFVEngine2]}]


which is correct

Issues:

THere is a bug in SailGraph.java

https://github.com/tinkerpop/blueprints/blob/master/blueprints-sail-graph/src/main/java/com/tinkerpop/blueprints/pgm/impls/sail/SailGraph.java

to do with processing the results.

d) Committing

see https://github.com/tinkerpop/blueprints/wiki/Graph-Transactions-Helpers

I have not ben able to get this to work. The default is automatic mode transactions which is bad I think.

To set to manual mode do:

getSailGraph().setTransactionMode(TransactionalGraph$Mode/MANUAL)
