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

Hi Henry,

I think it's a great idea, and you can count me in. Right now, there are a
number of disconnected threads on CT + graph data models and semantics
which I think would benefit from a central place to interact. I know next
to nothing about HoTT, but am interested in learning, and I am also
interested in connecting the work Ryan and I have done on type algebras for
graphs with yours on RDF semantics and modal logics. We can bounce topics
around between the community group and local meetups like this one
<https://www.meetup.com/Category-Theory/>, compare notes on applied CT in
industry, etc.
