---+ Using the <code>{is property of}</code> syntactic sugar to express inverse relations in Turtle


---++What?
Virtuoso parser supports using <code>{is property of}</code> syntactic sugar to express inverse relations in Turtle.

---++Why?
Virtuoso's Turtle parser tries to handle as much N3 and NTriples syntactic sugar as possible, to maximize convenience for human Turtle writers. 


---++How?

---++Example

   1 Assume the following statements about <b>Alice</b> are true:
      * Alice has two children, <b>Bob</b> and <b>Charlie</b>.
      * In 1999 Alice has written a <b>book</b> titled as <b>"My Life"</b>.
      * Alice lives near <b>London</b>.
      * Alice's parents are <b>Edna</b> and <b>Fred</b>.

   1 Upload the Turtle file to [[https://s3.amazonaws.com/webid-sandbox/Enhanced-Turtle-Example.ttl][https://s3.amazonaws.com/webid-sandbox/Enhanced-Turtle-Example.ttl]].
   1 Load the Turtle file into Virtuoso using any of the following methods and the file's URL:
      * [[VirtTipsAndTricksIsPropertyOfSyntaxInTurtleLOAD][Example using SPARQL 1.1 LOAD feature]];
      * [[VirtTipsAndTricksIsPropertyOfSyntaxInTurtleConductor][Example using Virtuoso Conductor]];
      * [[VirtTipsAndTricksIsPropertyOfSyntaxInTurtleSponger][Example using Virtuoso Sponger]];
      * [[VirtTipsAndTricksIsPropertyOfSyntaxInTurtleCMD][Example using Command-line Turtle Loader]] .
