I am going to stay on the topic of datasets.
The definition is rather broad. On one hand, we heard from witnesses on Tuesday about the benefits of having a broader definition; they claimed that it would keep agencies from having to play a constant game of catch-up. The pace of technological change is something that comes to mind.
On the other hand, I wonder whether there isn't cause for concern, since we don't know what this type of data collection—which the various agencies need to carry out their mandate—will look like in five or 10 years.
