What about inchi? Isn’t that a common way of describing molecules as well?

InChI isn't really meant to be used as a format to store 2D molecules say for rendering but rather serves as a unique descriptive chemical identifier. InChI has many flavors but the Standard InChI yields one unique identifier for multiple forms (tautomers) of the same molecule.
