I'm interested in using Jena to build a fault diagnostic, ontology-based expert system. Is it possible to perform i/o from within forward- or backward-chaining rules? For example to prompt the user for further facts? Or to access a database?

Sure, you just write a built-in that does some I/O. There are already built-ins that do output (like printing). Did something not work about this approach? – Joshua Taylor Jun 15 '16 at 18:18

Thanks! I am just researching which tool to use and have struggled with I/O in other tools, so just wanted to check its feasibility in Jena. – Martin Lambert Jun 17 '16 at 10:31
