WebAbstract. We prove that the isomorphism relation for separable C∗-algebras, the rela-tions of complete and n-isometry for operator spaces, and the relations of unital n-order isomorphisms of operator systems, are Borel reducible to the orbit equivalence relation of a Polish group action on a standard Borel space. 1.
