[Pellet-users] Using Jess API and Pellet OWL-API, possible?

[Koh Shu Lin]

Hi all, Please mind me for my ignorance. I'm also wondering whether is there any possibility of creating my own builtins (swrlb: add, swrlb:multiply etc.) that can be supported by Pellet. If so, what should I take note to allow Pellet to support them when creating my builtins? If to use Pellet solely can't help in dealing with the unsupported builtins, what other suggestions (besides waiting for the release of Pellet 1.6) would you guys recommend based on your experience? Thanks in advance.
