Hi Alberto,
I'm merging this request.  

After it has deployed to Development, please load the collection data into 
the Development instance via Jenkins so that the Product Owners can review.

After the data load, please "deliver" [the story](https://www.pivotaltracker.com/story/show/78583656) in Pivotal Tracker.
