Conversion to DataSets and WellKnown files milestone

Users have not yet been converted to WellKnown files, but ultimately they need to be. The good news is that Web access is working again. The bad news is that at the moment, none of the potential of DataSets and WellKnown files is being used--Web access is the same as it was before. Web can currently only access the contents of the Main dataset.

So there's still a great deal of work left.
