Hi Jim,

We think it is premature to discuss the details of rule-related standards in event processing in the absence of an agreed upon event processing reference architecture.

Opher Etzion and I co-chair a working group focused on EPRA which was the product of a group of experts who agreed with this position.





Yours sincerely,  Tim

Hi Marco,

It would be great if we could have a working group set up to develop this.  Anybody have any ideas about what that forum would be.  Certainly the OMG would be one place to do this.

        Paul, Jim & Group,
       
        I would be really interested in taking part on working on ECA style of
        rules.
       
        The RuleML group has (had?) a Reaction Rules Technical Group, but there
        is not much action there. I asked on their mail list a while ago if
        anybody had an interest to continue that work, but at that time there
        were no interest, or perhaps lack of time. Maybe this could be a new
        fresh start for that group and the work done in that group.
       
        As I have been working on a rule engine for reactive rule for some years
        now, I think I could hopefully contribute to such work.
       
        To begin with I strongly believe that production and rules and
        reaction/ECA rules should be handled by different groups as you suggest.
