CRDT is a general concept, editing text is just one possible application. If you have a stronger datatype, great, you can build operations on top of it to implement a CRDT system, depending on its properties.

It would be a little bit strange to build a CRDT system on top of a more traditional data system. CRDTs solve problems at the network layer at enormous cost basically everything else. If you're not using them there, I can't quite understand what they're doing for you?

What I've read talks about character insertion and concepts that apply to editing text.

Perhaps I just need to find bedrock to build up from about the properties of a stronger datatype that allow CRDTs to work.

https://arxiv.org/pdf/1805.06358.pdf looks like a decent starting point, with references to work on other types.

and pointers to other papers, too - thanks!
