I think we shouldn't underestimate the difficulty in integrating datasets, and David alluded to it.
The difficulty in taking two open datasets and aligning them, figuring out if two records actually refer to the same corporate entity—if the data that they represent is actually consistent with each other, if one is in metric and one is in imperial units—is an incredibly difficult problem. It is one that requires today, with current technology, many human years of intervention in order to really align two datasets. It's a very difficult problem. My advice would be to strategically pick areas where we can see real economic benefit in aligning the data with other G-8 countries.
