If you have a question about this talk, please contact Paul Levy.

I will discuss where we are, and where we are going, from the perspective of data type definition, also known as initial algebra semantics. I will suggest that our goal is often to define what are known as universes, or functions of the form T:U → D where U is “small” and D is large “D”. Within this program I will suggest three well behaved definitional formats: i) containers which accounts for the case where T is a constant function; ii) indexed containers where U is defined in advance of T; and iii) inductive recursive definitions where U and T are defined simultaneously.
