> Make the DataSchema and QuerySchema classes agnostic of their potential persistent representations,
then have 'providers' that applications can use to load/store in a variety of formats.
> For example, in LoadDataSchemas, the data schema XML file is parsed to create a DataSchema
object (one for each data schema specified). The DataSchema object could be created from other
sources.
> Perhaps JSON representation would be a good starting place.
