Subject: Re: [rules-dev] drools spatio-temporal<br>Hi again Marco, yes I&#39;m totally interested, but when you mention spacial operators how are you coding that?<div>I&#39;ve
 already mention to you that we have a couple of very simple accumulate 
functions to do something similar.. but in the jBPM forum you mention 
that you are creating a set of operators. I&#39;m just interested to see how
 you are creating those mechanisms.</div>
Cheers
