// Create an empty graph database

graph = TinkerGraph.open()

// Create the TraversalSource

g = graph.traversal()

// Create the "person" vertex and assign it to "v1"

v1 = g.addV('person')\
      .property(id, 1)\
      .property('name', 'marko')\
      .property('age', 29)\
      .next()

// Create the "software" vertex and assign it to "v2"

v2 = g.addV('software')\
      .property(id, 3)\
      .property('name', 'lop')\
      .property('lang', 'java')\
      .next()

// Create the "created" edge from "v1" to "v2"

g.addE('created')\
 .from(v1)\
 .to(v2)\
 .property(id, 9)\
 .property('weight', 0.4)

// Get the name of the software created by "marko"

g.V()\
 .has('person', 'name', 'marko')\
 .out('created')\
 .values('name')
