In the course of our work at sones GraphDB 2.1 we refac­tored our index inter­faces to make them more suit­able for our needs. Fur­ther­more, we wanted to make it eas­ier for the com­mu­nity to imple­ment cus­tom index struc­tures for their spe­cial needs. For the lat­ter rea­son we set up a tuto­r­ial and pub­lished a sam­ple imple­men­ta­tion on github.

The inter­faces are explained in our devel­oper wiki, the tuto­r­ial can also be found there. The source code regard­ing the tuto­r­ial is located at github.
