Yjs solves many of the current issues for concurrency control and consistency maintenance approaches in collaborative software. In order to achieve this, we created a new approach for optimistic concurrency control, which was formally proven to be reliable and to output the best time complexity (compared to existing dedicated related literature). The approach was designed to support real-time shared editing on linear, tree and graph data structures. A short part of this lightning talk aims to present the core concepts of our approach.

Designed to work on both peer-to-peer and client-server architectures, Yjs can be easily embedded in Web applications in order to foster collaboration. Developed in Javascript, the framework outputs very good scaling capabilities in the number of users and operations in test environments. Yjs currently supports text, JSON and XML data types and was tested using WebRTC and XMPP as an underlying communication protocol.

In this lightning talk, the Yjs framework will be presented to the wider OS community for the first time. We consider our framework to be developer friendly, but given the opportunity of a lightning talk, we would like to invite FOSDEM developers to use Yjs and share with us their experience. Ideally we aim to establish connections and potential collaborations, in order to improve our open source project.
