Re: Category Theory CG? was: Algebraic Property Graphs and RDF

Hi Henry,

I’m curious about practical implications on software development.

I don’t know anything about CT, but the dependent types and functions in
your blog post read a lot like domains and functions in denotational
semantics:
http://people.cs.ksu.edu/~schmidt/text/DenSem-full-book.pdf#page=27

I have used DS to (attempt to) formalize Linked Data Templates -
SPARQL-based definitions of Linked Data APIs:
https://atomgraph.github.io/Linked-Data-Templates/

Your examples seem to model HTTP interactions. But I think it’s the server
processing of interactions that needs to be modeled, if we are aiming for
formal interoperability on the web.
