-/* DataSource*/
-/* */
-/* A DataSource is an object that is unique throughout the system.  DataSources*/
-/* commonly have external and/or persistent representations, hence they have a notion of being*/
-/* destroyed (versus removed or freed).  Several DataViews may exist that reference a single*/
-/* DataSource.  Note that DataSources MUST be destroyed (rather than simply removed) from their*/
-/* SourceCollection, and that they MUST be destroyed via their SourceCollection (rather than*/
-/* calling DataSource.destroy() directly.)*/
-/**/
-/* Destroying a DataSource indicates it should remove all secondary and tertiary structures (such*/
-/* as thumbnails) and any records pointing to its backing store.  SourceCollection.destroy_marked()*/
-/* has a parameter indicating if the backing should be destroyed as well; that is when*/
-/* internal_delete_backing() is called.*/
-/**/
-/* There are no provisions (currently) for a DataSource to be removed from its SourceCollection*/
-/* without destroying its backing and/or secondary and tertiary structures.  DataSources are intended*/
-/* to go to the grave with their SourceCollection otherwise.  If a need arises for a DataSource to*/
-/* be peaceably removed from its SourceCollection, code will need to be written.  SourceSnapshots*/
-/* may be one solution to this problem.*/
-/**/
-/* Some DataSources cannot be reconstituted (for example, if its backing file is deleted).  In*/
-/* that case, dehydrate() should return null.  When reconstituted, it is the responsibility of the*/
-/* implementation to ensure an exact clone is produced, minus any details that are not relevant or*/
-/* exposed (such as a database ID).*/
-/**/
-/* If other DataSources refer to this DataSource, their state will *not* be */
-/* saved/restored.  This must be achieved via other means.  However, implementations *should**/
-/* track when changes to external state would break the proxy and call notify_broken();*/
