# Are Mathematica's datasets valid?

I, being an avid Mma user, sometimes use its many datasets (such as ElementData) for golfing purposes. However, these require the Wolfram Research servers to have the data. As I'm not directly connecting to the Internet, I am wondering if this would be considered a loophole.

Whether built-ins are allowed or not depends on the particular challenge in question. Using built-ins is no longer an accepted standard loophole, so unless the challenge rules them out explicitly, any of the *Data functions should be fair game.
