Consists of a scheme $X$, satisfying the following properties:
$X$ normal, connected, irreducible, dimension 1, reduced, not noetherian, pure dimension 1, regular, locally noetherian, integral, not separated, not quasi-compact, cohen-macaulay, not affine, all stalks of the structure sheaf are domains
By the theorems, we also have {"X": {"quasi-separated": true}}
