I note that AllegroGraph has its own Java API; and I also read this in their Java tutorial:
"This release of AllegroGraph includes interfaces that allow applications to access and manipulate data in AllegroGraph triple stores with Jena or Sesame 2.0 API calls. These interfaces are early releases that may be incomplete and only partly documented."
I don't like the idea of 'incomplete and only partly documented', but Jena does seem to have a following. Which API would you advise me to use with AllegroGraph?
