  The foundations of Ringel duality for split quasi-hereditary algebras over
commutative Noetherian rings are strengthened. Several descriptions and
properties of the smallest resolving subcategory containing all standard
modules over split quasi-hereditary algebras over commutative Noetherian rings
are provided.
  In particular, given two split quasi-hereditary algebras $A$ and $B$, we
prove that any exact equivalence between the smallest resolving subcategory
containing all standard modules over $A$ and the smallest resolving subcategory
containing all standard modules over $B$ lifts to a Morita equivalence between
$A$ and $B$ which preserves the quasi-hereditary structure.
