I’ve been looking into the Drools Fusion Complex Event Processing component and the WSO2 Complex Event Processor/Siddhi and I was wondering if one/both of these components are capable to handle spatial events for 2D and 3D events.
I’m interested in creating triggers such as:
Are these triggers such as these possible to create or do I need to write extensions/ custom functions?
If spatial event are possible, where can I find some documentation that I can look into.
What I’ve found so far:
Drools Fusion: http://blog.athico.com/2009/10/secret-sauce.html | Indicating that spatial based questions should be possible (It’s an old source however).
Rules engine for spatial and temporal reasoning? | Similar question but it’s very old
WSO2 Complex Event Processor/Siddhi: [link]: wso2.com/about/news/wso2-vp-of-platform-evangelism-to-lead-workshop-on-improving-team-performance-with-big-data-streamin/ & [link]: prweb.com/releases/2014_WSO2/03_StructureData/prweb11661730.htm | “spatial and temporal processing” are talked about.

(Sorry for the [Link]: part, i can't seem to post more than 2 links since I'm new here.)
Thank you for your time and effort!
Best regards,

I won't be able to answer regarding support in Drools Fusion since am not much aware of Drools. Regarding WSO2 CEP, you can find some articles in [1,2]. More functionalities are being added to Siddhi as extensions by using external libraries as discussed in the architecture@wso2.org mail thread pointed out by you in the question.
Also there is some work for a geo dashboard done in [3]. There are no publicly available articles/ tutorials as yet on these, but you can drop a mail to dev@wso2.org to get more info on the implementation details, capabilities, if you are interested.. :-)
