  We describe how to formulate Khovanov's functor-valued invariant of tangles
in the language of bordered Heegaard Floer homology. We then give an alternate
construction of Lawrence Roberts' Type D and Type A structures in Khovanov
homology, and his algebra $\mathcal{B}\Gamma_n$, in terms of Khovanov's theory
of modules over the ring $H^n$. We reprove invariance and pairing properties of
Roberts' bordered modules in this language. Along the way, we obtain an
explicit generators-and-relations description of $H^n$ which may be of
independent interest.
