title: ArangoDB create Vertex REST API without knowing the vertex id's
body: <p>Is there a way to create with ArangoDB an Edge with REST API without knowing the Vertex ids? With a query to find the vertexs and link them?</p>
  
  <p>Like this with OrientDB: create edge Uses from (select from Module where name = 'm2') to (select from Project where name = 'p1')</p>
  
  <p>I don't want to query via REST the two vertex before, and after create the Edge. I don't want to use Foxx also.</p>
  
  <p>Perhaps with AQL?</p>
  
  <p>Thanks.</p>
