Renato Javier MarroquĂ­n Mogrovejo commented on SAMZA-390:
---------------------------------------------------------

I find this paper very comprehensive when defining temporal features over

Another interesting open source project is Esper, it has a very good SQLish 
syntax. It is worth looking at it for sure.
