parse verb. resolve (a sentence) into its component parts and describe their syntactic roles.
In computer science what we do is precisely syntax analysis. Determining the meaning of operators.
Mathematicians have the exact same problem with respect to the equality operator.

In that case your former statement that 'The word "is" implies an isomorphism' seems to be wrong.
It may be wrong in your model/interpretation of my words, but it's not wrong in my interpretation of my words.
In what interpretation is it consistent for 'A square is a rectangle" means "A square is a TYPE of rectangle"' and 'The word "is" implies an isomorphism' to be simultaneously true? No matter how I cut it, the latter seems to prevent the former to me.
"A square is a rectangle" means "A square is a TYPE of rectangle" (at least, that is what I am parsing it as).
"Parsing is Validation" means Parsing is isomorphic to Validation.
How do I know? Because that is how I want you to parse it.
