As chronicled in your researcher's journal as I researched my history of early lifestyles in South Asia...
An Indian archaeological journal mentions that someone was given training in the rudiments of archaeology which included not only excavation but displaying the finds in museums and keeping them from falling apart. That wasn't surprising. But they also were careful to teach the "layout of gardens." (A lot of archaeological sites here after the excavation are covered over with gardens.)
