Hi, I'm currently on a R&D project and I try to develop a small program which allow to do : - Load file.rdf - Convert SPARQL construct query to SPIN rule. - Reason the file.rdf with the SPIN rule.
So I already develop 2 java classes (attached). 1. I create Model and read my file.rdf. 2. I convert my construct query which is in a Model. 3. I add my Model which contain my SPIN Rule to my Data Model. 4. I run Inference. 5. Fail :( Could you say me why it fail ?
