What was the content of the 20 million gigaquads uploaded to Voyager's computer in the episode entitled "Twisted?"

In Star Trek Voyager, Season 2, Episode 6, "Twisted" there is an alien life form that is trying to communicate with voyager through a distortion ring/energy field. At the end of the episode the alien communicates by uploading 20 million gigaquads of data to Voyager's computer. Is there any record of the actual contents of the data? Is any of it technology based? Do we ever learn in any novels or anything else canon anything about the content of the data or who the aliens were that deposited it?
