The JPG extractor has been introduced to Aperture only last week. It is 
in SVN. We are working on it. Thanks for your email. This will certainly 
be a motivation to finish the JpgExtractor soon.

The examples produce RDF serialized as XML. Currently there is no way to 
  configure this behaviour. You could use the example code as a guide to 
write your own programs that produce output in other formats (Turtle, 
Ntriples etc.). For more information you could consult the RDF2Go Tutorial
