First, we prove that shallow embedding is injective up to definitional equality, by modelling the embedding as a syntactic translation targeting the metatheory. ...
There are multiple ways to formalise the metatheory of type theory. ...
Compared to a previous formalisation using a deep embedding [3] , it is significantly shorter (322 vs. 1682 lines of code -we only counted the lines of code for the substitution calculus, Π and the universe ...

On the contrary, a deep embedding is better intuitively described as the development of a virtual machine: the syntax and the semantic of the guest logic are formalised as datatypes of the host logic. ...
