How can I glue/identify inclusions in two structures in MMT?
问题 I'd like to formalize formal languages and their semantics in MMT and define a general notion of semantics equivalence of two semantics wrt. one syntax. Precisely, encoding the latter turns out to be an identification/glueing that I have no idea on how to do in MMT. Let me elaborate on my concrete formalization setup next. Below is a simplified formalization showing my approach. Based on a theory Meta aggregating both the logical framework LF and some logic, I start in Syntax defining a
