Hi! We have been researching CRDTs as underlying data structure for an ActivityPub server in the context of the openEngiadina project.
We have an initial write-up of the ideas: Distributed Mutable Containers.
This should also be very applicable to a service implementing the Linked Data Platform.
There are many implementation details missing (e.g. “How to map ActivityPub to these containers?”). We intend to implement the containers in an ActivityPub server to gain further insight.
Very happy for comments and feedback.
