If I read the documentation correctly, one needs to create "JSON0 OT Type" records for any change in the target data-model and send these to the ShareDB backend for transformation and forwarding to other clients. There also seems to be a newer "JSON1 OT Type".
Since I have a libray which already produces JSON-Patch records, I was wondering if it is possible to use this JSON-Patch (CRF-6902) standard to specify the changes to the ShareDB backend.
