[rules-users] Checking facts between them

[Delaunay Gaetan]

Hi all,

I was wondering if  it was possible to create a rule which checks if a 
fact is equal to another one. For example in my case i'd like to compare 
the date of fact with the date of fact +1. I hope you understand what i 
mean.

What kind of rule will be suitable to do that?

Thanks
Gaetan
