[chef] Sharing Variables across Recipies

[Kamesh Sampath < >]

I have situation in my cookbook where i extract some values form data_bags 
and put them onto local variables on recipes after some manipulation of them. 
 I am running on to a situation where i need to repeat this logic across many 
cookbooks as i see that when i do it in “default.rb” and then use them in 
include_recipe’s I see chef complaining that the variable is undefined, am 
not sure why so ideally when if I understand correctly all the recipes are 
compiled on to a single class by chef during converge so conceptually they 
should be visible.

Is there a way how i can share the variables declared in a recipe?
