5 years ago To start, we need a function comp_map that, given
m1 :: Mapping var ty sym en fk att en’ fk’ att’ m2 :: Mapping var ty sym en’ fk’ att' en’' fk’' att’’
Such that dst m1 = src m2, returns
comp_map m1 m2 :: Mapping var ty sym en fk att en’' fk’' att’’
Such that src (comp_map m1 m2) = src m1 and dst (comp_map m1 m2) = dst m2.
The entity mappings compose directly. Composing the term mappings requires substitution.
