Hello EuAndreh,

I read your blog post with excitement because I'm currently on a very
similar quest. My goal is to bring back application data into the hands
of the users (and onto their devices) to replace centralized,
cloud-based data stores. I wrote down what I wanted in this blog post
[1].

Like you, I didn't find anything that seemed to work like I wanted, so I
decided to start exploring the problem myself. While you go for the
Git-like approach of three-way-merges, I am trying to model conflict
situations with completed categories.

I can't say that I've come very far yet. I realized that properly
modelling conflicts with completed categories is a hard problem and
while I had some progress already, there isn't anything that I would
consider ready to be shared just yet (if you're curious you can look at
the source [2]).

But through discussions on lobste.rs [3] and further research I built a
list of references, prior work and concepts in this space [4]. From your
blog post I even got a few more references that I just added :) Perhaps
this list is also useful for you.

I wish you the best of luck with your endeavor and I hope to see further
posts about your progress on the blog :) When I have more time I will
also write more about what I've found and what's next.

Cordially, Jonas Schürmann

Hmmm, I haven't heard this term before. Are these [0] the complete
categories that you mean?

Thanks for all the links, I'll try to use them to enrich my
understanding on the subject.

Yes, exactly. The idea is pretty abstract and while I know a little bit
about category theory I'm by no means an expert on the subject. This
blog post [1] is a very down-to-earth, practical explanation how the
concept of (co)completed categories can be applied to conflict
representation in version control systems.

This sounds interesting, thanks for the link.
