Hi Alex, Yes, in most EPA types this is possible (not in aggregate or absent EPA types). When you define the derived event of the EPA, you can open a table that contains all the attributes of the derived event. You can assign the attributes values. For example, you can set value of an attribute named "triggerEventID" (any attribute name that you defined in e2) to e1.ID (assuming e1 has an attribute named ID, make sure both attributes in e1, e2 have the same type). See example here: Hope it helped, Tali Regards, Tali Tali Yatzkar Haham Event-based Middleware & Solutions IBM Haifa Research Lab, Israel tali at il.ibm.com 972-4-8296320 From: Theologos Zacharopoulos <alex at konnektid.com> To: Tali Yatzkar-Haham/Haifa/IBM at IBMIL Date: 25/03/2015 12:42 PM Subject: Re: Complex Event Processing, help Dear Tali I have one more question about the Complex Event Processor, I trigger an event (e1) from my system with an ID, after that there is some processing in the CEP and if the conditions I set are true I derive a "command" event (e2) that through an adapter I get it back to my system. The thing is how can I understand from which trigger event (e1) the command event (e2) was triggered? In a perfect solution I would like in the EPA my derived event (e2) get the ID from the participant events. Is that possible? set a value on a field of an event during the derivation in the EPA?

What you can do: 1. Have one EPA, lets call it EPA1, that uses the temporal context you defined, lets call it TC1, (initiator Event_X, terminated after 24 hours). Make EPA1 of type Aggregate, that uses TC1. Set the evaluation policy of EPA1 to be deferred and don't set it conditions or input event. Make it generate a new type of event (that you need to define), lets call it E2. The purpose of EPA1 is to generate E2 24 hours after Event_X arrives. (If you don't want to have a warning on empty input events you can put Event_X as an input event of EPA1) 2. Now you can define another temporal context, lets call it TC2 that uses E2 as initiator. Hope this is what you wanted. I cc the FIWARE help, so this corresponding will be documented in the FIWARE issue tracking system. Please cc it as well in future correspondence. Thanks.

I created a temporal context that starts the time that an Event_X is fired and it expires after 24hours, but I want a second temporal context start after 24hours of the event creation, can you please provide me some help on this? I tried to set the condition: Event_x.duration == 86400000, but that didn't work for me. Thanks in advance!
