This sounds like great work; been playing with graph dbs lately and it makes things easier. I was hoping though that there would be an effortless offline component to it though; maybe I missed it but there seems to be none? We have been trying to find a replacement for couch/pouch which gives the same convenience as that combo (besides setting up the right filters and permissions, everything works automatically). I see many people rolling (usually very hacky ‘cache invalidation’) solutions which require a lot of domain knowledge where pouch just works and querying server and client (mostly) the same way also lightens the load a lot. Couch is old and works very well, but, besides being very good at synching, it has a lot of downsides which we just ignored (which worked for us for a decade and very well at that), but with we are not good with couch (erlang) as rust/go/ts team and with the advances in webasm and anything-to-js, as well as having bucketloads of memory and storage on most non-iot (but even some of those if done with care) edge devices these days, you would think there would be a solution that allows me to do this outside couch/pouch. Of course here I forget to mention; although we would not mind paying for it, it needs to have an actual OSS license (not open core but apache/mit/bsd or whatnot). And yes, we might have a go at it ourselves but we are swamped at the moment.
Edit; the project has ‘eventual FOSS’ which I like as a concept and thought of doing myself; put milestones in place which can be externally verified which will trigger the license of the (semi) closed product to become fully foss.
