Two lines of Stardog

StardogExample.groovy

def stardog = new Stardog([embedded:true, createIfNotPresent:true, home:"test/stardog", to:"testgroovy", username:"admin", password:"admin"])
stardog.query("select ?x ?y ?z WHERE { ?x ?y ?z } LIMIT 2", { println it } )
// in this case, it is a BindingSet, ie TupleQueryResult.next() called until exhausted and closure executed

// as of Stardog-Groovy 0.2, there is now a projection of the results into the closure's binding
// if x, y, or z are not populated in the answer, then they are still valid binidng but are null
stardog.each("select ?x ?y ?z WHERE { ?x ?y ?z } LIMIT 2", { 
  println x
  println y
  println z // may be a LiteralImpl, so you get full access to manipulate Value objects
  } 
)

// Variables retain their  types from however the query results were populated, so URIImpls, Value,
// Literals, etc are all preserved in one heterogeneous Groovy map serving as the closure's delegate

// insert and remove
stardog.insert([["urn:test3", "urn:test:predicate", "hello world"],
		["urn:test4", "urn:test:predicate", "hello world2"]])
stardog.remove(["urn:test3", "urn:test:predicate", "hello world"])
stardog.remove(["urn:test4", "urn:test:predicate", "hello world2"])

// withConnection
stardog.withConnection { con ->
  	def queryString = """
		SELECT ?s ?p ?o
		{ 
		  ?s ?p ?o
		}
	"""
	TupleQueryResult result = null;
	try {
		Query query = con.query(queryString);
		result = query.executeSelect();
		while (result.hasNext()) {
			println result.next();
		}
				
		result.close();
						
	} catch (Exception e) {
		println "Caught exception ${e}"
	}
}

Hi Al, is it possible to load a DB already created by using stardog command line client or a OWL file stored in my filesystem?

I'm trying with this syntax:

def stardog = new Stardog([embedded:true, createIfNotPresent:true, home:"", to:"", username:"admin", password:"admin"])
